Do you really want the code exit the main function? As far as I know, Keil compilers cross-compile for microcontrollers...

Solution 1

the correct statement is

C

return;

For instance:

C

if (onevalue()==1)
    {
        printf ("Error");
        // what is the experssion here to stop this function (main function)  
        return; //<-- it's return!
    }

Solution 2

You can have more than one return in a function. Since this is main(), you may wish, instead, to consider an exit function, instead.

There should be no reason, however, that you cannot use:

if (onevalue()==1)  {
        printf ("Error")
        return;
}

or, wrap the whole thing up as:

void main() {
 if (onevalue()==1)  {
   printf ("Error")
 }
 else {
   for (int i = 0; i<3; i++)
   printf ("here :%d \n" ,  i);
 }
 return;
}
