 Posted: Tue Nov 27, 2012 5:42 am Post subject: Printing from inside a function with SCC? |
 |
|
I drew a simple function, intended to print out a single line (with several carriage-returns). But for some reason it doesn't.
First the main program should print out a carriage return followed by "Hello, world! Value =" followed by an integer value, then a couple carriage returns. Then it should print "Function writstat has been entered" with a couple more carriage returns, and then a single integer value.
I expected to get a garbage value (actually a pointer value) back, and I did. No surprise there.
But why it doesn't print out "Function writstat has been entered" with the carriage-returns?
---------------------------------------------
#include "stdio.h"
int writstat()
{
int i;
i=13;
printf("\nFunction writstat has been entered.\n\n");
return(i);
}
main()
{
printf("Hello, world! Value = %d\n\n",writstat);
}
--------------------------------------------------- |

It's simply because you never call the function writstat in your code, you are missing () after the function name.
There are other errors in your code:
- standard headers should be included as:
- main function should return a integer value. Old compiler assumes this and let's your code compile without nagging, but it's still a good habit. |

That was it! Thank you!

I have now corrected my code to include these. Thanks for your help! |
