Programming Language Questions and Answer

Programming Language Questions and Answer

What is a Program?

Ans: Instruction set that a computer can understand.

What is an Algorithm?

Ans: Solving a specific problem in a logical and sequential way.


What is a Flow chart?

Ans: A diagram base process that solves a specific problem with some special symbol.

What is a C program?

Ans: A high-level and general-purpose programing language.


What is Data type?

Ans: An extensive system used for declaring variables or functions of different types, integer, float, character, string, etc are data types used in C.


What is a compiler?

Ans: A type of translator that converts high-level programming language to machine language. In other words, it converts the source program into an object program.

What is an Interpreter?

Ans: It converts high-level language into machine language just like a compiler. However, the interpreter executes the line and shows the immediate result.


What is Structured programming?

Ans: Edgar D Costa first gave the idea of structured programming for developing a large program. In the structure model, the whole problem is divided into different parts or modules.


What is Expression?

Ans: Combination of the different signs is called expression. An expression is created by using different signs or symbols. This sign or symbol is called an operator.

What is a keyword?

Ans: There are some reserved words called keywords in every programming language that are used while writing programs.


What is Function?

Ans: If the value of a variable is dependent on another variable it is called a function. Function means mathematical relationship.

What is a Variable?

The name used to store the data in memory.


What is Constant?

Ans: If the value of an expression remains unchanged, then it is called constant.

What is an operator?

Ans: The sign or symbol used in an expression is called an operator.


What is Array?

Ans: Array is a collection of the same type of data.


What is Looping?

Ans: Looping is a sequence of instructions that is continually repeated until a certain condition is reached.

What is biological coin?

What is a biological coin? ATP is called the energy coin of the cell because it can store energy and can supply that energy to the cell's demand. ATP (Adenosine triphosphate) is known as 'biological currency' or energy coin, where energy is stored and can be used whenever the cell demands it.  Energy is released from the photosynthesis process to generate foods through respiration. Usually, this energy is stored within ATP in the bond of the terminal phosphate group. When this bond is broken, energy is released, which can be used in different physiochemical reactions. The basic mechanism of production and utilization of energy in the body of a living organism is its bio-energy. This is not very different from the definition of energy given in physics. The energy we get from making and breaking chemical bonds in the molecules found in biological organisms is called by this name. Living organisms continuously collect energy from the environment, transform them one from on

Development of physics

Modern civilization is the product of science. Behind this development of science, there are untiring efforts, discoveries, and innovations of scientists. Science has no national or political boundaries. The growth, development, and benefit of science are enjoyed by all people of all nations. From ancient times scientists have been contributing to the development of science. In this lesson, we will try to mention the contributions of physicists.  Thales (624-569 B.C) is famous for his predictions regarding solar eclipse. He also knew about the magnetic properties of the loadstone. Pythagoras (527-497 B.C) is a memorable name in the history of science. Besides the invention of several Geometric theorems, he made a longer-lasting contribution through his works on vibrating string. He was given several Geometric theorems. Moreover, he made long-lasting contributions through his works on vibrating strings. The present scales of musical instruments and music are partially the contribu

When you open the gas cylinder used for cooking, which action takes place first diffusion or effusion?

When you open the gas cylinder used for cooking, which action takes place first diffusion or effusion? The pressures of the ingredients of body spray inside and outside of the container are not the same. The pressure is greater inside the container. When the molecules of the gas come out through small pores into a low-pressure zone from a high-pressure zone, effusion happens. Due to the application of pressure, the molecules present in body spray come out through the small pores. The spontaneous movement is blocked by the pore of the container. The bigger the pore size, the more spontaneous the movement is. When the condition becomes absolutely pressure-less, it becomes diffusion. So in the case of a body spray, first effusion takes place, then diffusion happens. You may like Do I need car insurance? What is car insurance? How could I get cheaper car insurance?

Meaning of Concept, Law, Principle, Postulates, Hypothesis and Theory in Physics

Meaning of Concept, Law, Principle, Postulates, Hypothesis and Theory in Physics What is Concept? The correct realisation or understanding of a subject is to have a clear idea about that subject. Or, concept is an idea or thought or a general opinion. For example, the idea of heat is a form of energy which when applied to a body or if the body is heated, then temperature increases and on releasing heat temperature decreases. What is Law? When a theory is proved by different experiments and its important facts are expressed by a statement then it is called a scientific law. For example, Ohm's law, Boyle's law and sometimes on the subject matter, e.g., conservation law of energy, thermodynamic law and sometimes on both e.g., Newton's laws of motion, Galileo's laws of falling body. What is Principle? The natural truth which can be proved directly and by the help of that truth many natural phenomena can be established, is called a principle. For example, Doppler's princ

What is a purple alert?

What is a purple alert? A Purple Alert is for missing adults with mental, cognitive, intellectual or developmental disabilities, not related to substance abuse or Alzheimer's or dementia-related disorders, which are in the Silver Alert section. Notifications go to the media, road signs, lottery terminals and those who have signed up. "It's like bringing it home a bit more, because I know what it feels like when your loved one goes missing." With Purple Alert, local law enforcement must decide that the matter is at risk of bodily harm and can only return safely through their intervention.

RUTHERFORD’S MODEL OF AN ATOM

Image
Ernest Rutherford was interested in knowing how the electrons are arranged within an atom. Rutherford designed an experiment for this. In this experiment, fast moving alpha (α)-particles were made to fall on a thin gold foil. He selected a gold foil because he wanted as thin a layer as possible. This gold foil was about 1000 atoms thick. α-particles are doubly-charged helium ions. Since they have a mass of 4 u, the fast-moving α- particles have a considerable amount of energy. It was expected that α-particles would be deflected by the sub-atomic particles in the gold atoms. Since the α-particles were much heavier than the protons, he did not expect to see large deflections. Scattering of α-particles by a gold foil But, the α-particle scattering experiment gave totally unexpected results. The following observations were made: Most of the fast moving α-particles passed straight through the gold foil. Some of the α-particles were deflected by the foil by small angles.

What is physics?

What is physics? The branch of science which deals with matter and energy is called physics. The main objectives of physics are to establish the relation between matter and energy and to express it quantitatively on the basis of observation, experimentation, and analysis. Physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. Physics is concerned with all aspects of nature on both the macroscopic and submicroscopic levels. Its scope of study encompasses not only the behavior of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields. Physics is basic physical science. Until rather recent times physics and natural philosophy were used interchangeably for the science whose aim is the discovery and formulation of the fundamental laws of nature. Physics plays an important role in all the natural sciences. However such fields hav
