Hello all, my latest assignment was to find the sum of 2 numbers using functions which I managed to do. I decided to try and get the multiplication tables of x up to 12 using functions. I get the error code: "undefined reference to xyz". XYZ is just a random name for the function. Any help would be greatly appreciated, thank you.
int xyz(int x);
printf("Enter the number for which you want a multipication table for: ");
int xyz(int x)
