Thread: I have...another question.

In my homework, my teacher gave us a piece of code asking,

"What would be the output of the following piece of code?"

The code is this:

Code:

include <stdio.h>
main() {
     int x;

     x=5;
     while (x < 7);
     {
          printf("value of x is %d\n", x);
          x = x + 1;
     }
     printf("final value of x is %d\n", x);
}

But when I run that, NOTHING happens! There is absolutely nothing on the screen. Not even "press any key to continue" or whatever. And "nothing" is not a choice...

I'm not asking for the answer, I'm just confused as to why nothing happens when apparently my teacher thinks it should. Am I doing something wrong?

check the faq: http://faq.cprogramming.com/cgi-bin/...&id=1043284385
you probably want to run the program from the console/command prompt. also, this is a c program not c++.

The code above will run forever without any output. Did your teacher actually say there would be output? If so, double-check that you copied it properly. BTW, it's good practice to specify the return type of main explicitly:

Code:

int main(void) {

You should normally also have "return 0;" at the end of main() in a C program, which this is, though here it doesn't matter since it never gets reached.

ah good eye, robatino. didnt see that semi colon!
