Jump Statements

The are used to make the flow of your statements from one point to another. break, continue, goto and return come under this statements.

# return Statement

return is a jump statement. Return statement has a special property that it can return a value with it to the calling function if the function is declared non - void. Void functions are the one which are explicitly declared not to return a value and hence a return statement with value when encountered in such a function leads to an error by compiler. Also a function declared non-void should always return a value of the respective type.

return expression;
Example of return
#include <stdio.h>
int function (void)
{
	int b;
	b = scanf ("%d", &b);
	return b; // returns the value of b to the calling function.
}
int main ()
{
	printf ("\n%d", function ());
	return 0;
}
