    im not to sure what you mean but as for dividing the 2 numbers here is an example

    Code:
    #include <stdio.h>
    #include <conio.h>
    
    int main(void)
    {
    	float num1 , num2;
    
    	printf("Enter 2 Numbers : ");
    	scanf("%f %f" , &num1 , &num2);
    	printf("%.2f Divided by %.2f is %.2f\n" , num1 , num2 , num1 / num2);
    
    	system("pause");
    
    	return 0;
    }

    also because they are floats it will have the remainder.

    difference is the values subtracted from each other

    difference between 1 and 5 is 4 (ie 5-1);

    so subract the values save the result as difference;
    multiply the values save the result as product;
    then take difference/product;

    You may teach a person from now until doom's day, but that person will only know what he learns himself.

    Now I know what doesn't work.

    A problem is understood by solving it, not by pondering it.

    I was confused about why it is I need to divide the difference by the product and what this would achieve, obviosly it was just an exercise and the output of the program was nothing but an argument passed to a function...
