  1. What is a Programming language and What is a Program?

-> A procedure expressed in a programming language is known as a COMPUTER PROGRAM.


What is a Program?

A computer program is a collection of instructions that can be executed by a computer to perform a specific task.

A computer program is usually written by a computer programmer in the programming language. From the program in its human-readable form of source code, a compiler, or assembler can derive machine code—a form consisting of instructions that the computer can directly execute. Alternatively, a computer program may be executed with the aid of an interpreter.

A collection of computer programs, libraries, and related data are referred to as Software. Computer programs may be categorized along functional lines, such as application software and system software. The underlying method used for some calculation or manipulation is known as an algorithm.

Programming languages can be divided into two categories:-

  • LOW-LEVEL LANGUAGE- The language whose design is governed by the circuitry and the structure of the machine is known as the MACHINE LANGUAGE. This language is difficult to learn and use. (it's only for machine to understand).
  • HIGH-LEVEL LANGUAGE-These languages are particularly oriented towards describing the procedures for solving the problem in a concise. Precise and Unambiguous Manner languages falling in this category are FORTRAN, BASIC, PASCAL, etc. It is also known as PROBLEM ORIENTED LANGUAGE.(easy to understand for humans).
INTRODUCTION:-
C- C is a programming language developed by AT&T's Bell Laboratory of The USA in 1972. It was designed and written by Dennis Ritchie.

FEATURES:-
  • Portable
  • Powerful Processor
  • Modular Programming language

"A program Written in LOW-LEVEL LANGUAGE is FASTER". Why?

A program written in a low-level language is faster to execute since it needs no conversions while a high-level language program needs to be converted into low-level language.

I hope, now you have a better understanding of program. Comments and suggestions regarding this article are welcome.

 What is a String? Write a function in C for string concatenation. Without the use of an inbuilt string function. String A string is a data type used in programmings, such as an integer and floating-point unit, but is used to represent text rather than numbers. It is comprised of a set of characters  that can also contain spaces and numbers. For example, the word "hamburger" and the phrase "I ate 3 hamburgers" are both strings. Even "12345" could be considered a string, if specified correctly. Typically, programmers must enclose strings in quotation marks for the data to recognized as a string and not a number or variable name . String concatenation in C C program to concatenate two strings, for example, if the two input strings are "C programming," and " language" (note the space  before language), then the output will be "C programming language." To concatenate the strings, we use strcat function of string.h, to concatenate ...

 What is the scope of a Variable? Explain the difference between global and local variables with example programs. A scope in any programming is a region of the program where a defined variable can have its existence and beyond that variable, it cannot be accessed. There are three places where variables can be declared in C programming language − Inside a function or a block which is called  local  variables. Outside of all functions which are called  global  variables. In the definition of function parameters which are called  formal  parameters. Let us understand what are  local  and  global  variables, and  formal  parameters. Local Variables Variables that are declared inside a function or block are called local variables. They can be used only by statements that are inside that function or block of code. Local variables are not known to functions outside their own. The following example shows how local variables are u...

What is a Pointer? Write a C program using a pointer to print the name and price of the items sold in a retail shop on a specific date.  Pointers in C are easy and fun to learn. Some C programming tasks are performed more easily with pointers, and other tasks, such as dynamic memory allocation, cannot be performed without using pointers. So it becomes necessary to learn pointers to become a perfect C programmer. Let's start learning them in simple and easy steps. #include <stdio.h> int main () { int var1 ; char var2 [ 10 ]; printf ( "Address of var1 variable: %x\n" , & var1 ); printf ( "Address of var2 variable: %x\n" , & var2 ); return 0 ; } What are Pointers? A  pointer  is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address. The general form of a pointer v...
