Procedural Programming:

 

1.  Tasks are divided into smaller procedures, functions or subroutines.
2.  A procedural program is largely a single file with many procedures and a function named main ()
3.  main () function integrates procedures by  making calls to them.
4.  When a procedure is called the control jumps to the called procedure or function.

Ex:  Fortran , ALGOL, COBOL,BASIC and C.
