Which of the following statements are correct about the below C-program?
int main()
{
int x = 10, y = 100%90, i;
for(i=1; i<10; i++)
if(x != y);
printf("x = %d y = %d\n", x, y);
return 0;
}
|
The printf() function is called 10 times.
|
The program will produce the output x = 10 y = 10
|
The ; after the if(x!=y) will NOT produce an error.
|
The program will not produce output.
