return in c

In computer programming, a return statement causes execution to leave the 
current subroutine and resume at the point in the code immediately after the 
instruction which called the subroutine, known as its return address. Return 
statements in many languages allow a function to specify a return value to be 
passed back to the code that called the function.

The return statement returns the flow of the execution to the function from 
where it is called. This statement does not mandatorily need any conditional 
statements. As soon as the statement is executed, the flow of the program 
stops immediately and returns the control from where it was called. The return 
statement may or may not return anything for a void function, but for a 
non-void function, a return value must be returned.
