    Need help woth fractions..

    Hi! i am new to C, so i want your help about a program. Could someone post any code on how to add two fractions, and checking the case of the zero denominator...thanks!

    my code is:

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    
    using namespace std;
    
    int main()
    {
    int a, b, c, d;
    char dummychar;
    int divisor, divident;
    
    printf( "Enter First divisor:");
    scanf("%d",&a); 
    printf("\n");
    
    printf("Enter the First divident:");
    scanf("%d",&b);
    printf("\n");
    
    printf( "Enter second divisor:");
    scanf("%d",&c); 
    printf("\n");
    
    printf( "Enter second divident:");
    scanf("%d",&d); 
    printf("\n");
    
    divisor = a*d + b*c;
    divident = b+d;
    how can i print the result..and how can i use an if statement to checking for zero divident?

    comparisons in c work like this
    Code:
    if(conditional) {
         code to be executed if conditional is true
    }
    You can work that into your program, then to print use printf.

    First of all, stick to C code if you're going to post on this forum, not C++. Second of all, we don't just do homework for people. Telling you how to use programming as a tool is one thing, but handing out finished code is quite another.
    If you understand what you're doing, you're not learning anything.

    snapshooter you have a little error there
    Code:
    a   c   a*d   c*b   a*d+c*b
    - + - = --- + --- = -------
    b   d   b*d   d*b     b*d  
    
    divisor = a*d + b*c;
    divident = b*d;
