Introduction Of C Language

C is high level programming language with some low level features.

C developed by Dennis Ritchie in 1972 at AT&T bell Laboratories (usa).
C is case sensitive language.

Rules Of C Language

Start the program with void main () function.

Write the program in lower case.

You must type (  ) end-of statement.
Save the program .c OR .cpp extension.Write all statement in carly breaks {}.
