C Programming

In 1972 Dennis Ritchie developed C language from ALGOL, BCPL and B, added the concept of data types and other powerful features at Bell Laboratory. To ensure that the C language remains standard, in 1983, American National Standards Institute (ANSI) appointed the technical committee, approved a version of C in December 1989 known as ANSI C. It is machine independent and is easy to learn and implement. It is concise and provides efficient translator for machine codes. 

Structure of a C program

Every C program consists of one or more functions. A function is nothing but a group or sequence of C statements that are executed together. Each C program function performs a specific task. The “main()” function is the most important function and must be present in every C program. The execution of C program begins in the main () function.

The figure below shows the structure of a C program.

main()                       function1()                 function2() {                      {                              {         statement1;                statement1;                        statement1;         statement2;                statement2;                        statement2;                ……;                   ……..;                         ……;         ……;                   ……..;                         ……; }                      }                              }
