Thread: Program to show a multiplication table

This program crashes. It allows me to enter a number that I want to multiply but then it just crashes instead of doing the multiplication.

Code:

#include <stdio.h>


int main()
{
    int sum, num1, count; /*Variable to hold count*/
    count=1; /*Count set to 0*/
    printf("Enter the number you wish to multiply:\n");
    scanf("%d" ,num1);
    
    while (count < 13) /*While count is less than 5 program loops*/
    {
    sum = num1*count;
    printf("Multiplying %d by %d is %d\n", num1, count, sum); /*Prints sum*/ 
    count = count+1; /*count adds one*/
   } /*End of while loop*/
    
    return 0; /*Exits the program*/
}

If I was next to you I'd give you a hug! I was trying to work it out for ages!

In all those ages, did it ever once occur to you to look up the descriptions for the functions in your program to see what the proper syntax is?

Even if your compiler doesn't have help files for it's library, all this stuff is out there...

Like.... THIS

And no, I'm not just being rude...
Checking function syntax is a routine task for every programmer. We do this dozens, sometimes hundreds of times a day.
There's no way you can remember all of it (there are hundreds of functions in the standard lbrary alone) so you either get
the help files for your compiler's library or you spend time bookmarking helpful sites...
