return

Causes execution to exit a function or program and go back to caller.

Statement Description
return Causes immediate termination of a function. Can pass a value back to the caller when a value is placed as its argument.

Example

int foo_1()
{
   a = 10;
   while(a)
   {
      if(a == 5)
         return a;
   }
}

foo_2()
{
   switch(a)
   {
      case 1:
         printf("1");
      case 2:
         printf("2");
      case 3:
         printf("3");
         break;
      case 4:
         printf("4");
