May be a printf within a printf would do the trick.Because the inner printf doesn't require the semicolon.

Here the statement finishes with a comma, not a semicolon:

#include <iostream>
 
int main() {
  printf("Hello"),
  getchar();
  return 0;
}
#include <iostream>

int main() {
  printf("Hello"),
  getchar();
  return 0;
}

Ahh, that's C+ code, didn't realize which forum this was. Try this:

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
#include <stdio.h>
 
int main() {
  printf("Hello"),
  getchar();
  return 0;
}
#include <stdio.h>

int main() {
  printf("Hello"),
  getchar();
  return 0;
}

You can also try this.

That's not correct, that just turns into:

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
#include <stdio.h>
 
int main() {
    printf("%s","string");
    return (0);
}
#include <stdio.h>

int main() {
    printf("%s","string");
    return (0);
}

Once the preprocessor's done.

Well what I meant was something like this :

 Help with Code Tags 
 c++ Syntax (Toggle Plain Text) 
#include<stdio.h>
int main()
{
       printf("%d%d",printf("Hello Daniweb"),printf("I am new here"));
       return 0;
}
#include<stdio.h>
int main()
{
       printf("%d%d",printf("Hello Daniweb"),printf("I am new here"));
       return 0;
}

You would get an output as
I am new hereHello Daniweb1313
The inner printf's are not using a semicolon as you can see.

"printf" function returns the count of characters it has successfully output on the console and it processes from right to left internally hence first it print I am new here and then Hello Daniweb and then count of the successfully output characters of each string which in this case is 13 13.
