C program to compute Quotient and Remainder

How to write a C program to compute Quotient and Remainder?

In this we will learn to write a C program to compute Quotient and remainder of two given numbers when they are divided. In other words, two number num1 and num2 are given and we need to find the Quotient and Remainder when num1 is divided by num2.

Syntax:

General code to compute Quotient and Remainder.
quotient = dividend / divisor;
remainder = dividend % divisor;

Example:

Simple example for better understanding of the concept:
Input: num1 = 2, num2 = 6
Output: Quotient = 0, Remainder = 2

Input: num1 = 17, num2 = 5
Output: Quotient = 3, Remainder = 2

Steps to compute Quotient and Remainder:

  • Step 1: Start
  • Step 2: Declare the variable num1=2, num2=4, Quotient and Remainder.
  • Step 3: Read input num1 and num2 from the user or predefine it according to the need.
  • Step 4: Use the syntax provided to find the Quotient and remainder while using num1 and num2 and store the value in variables assigned to them.
  • Step 5: Display the Quotient and Remainder in the stdout console.
  • Step 6: Program end.

Working:

In these program we will learn to compute Quotient and Remainder.

Example 1 :

A simple program where we will compute the Quotient and Remainder of two variables that are predefined.

Run 
#include<stdio.h>
int main()
{
    int num1, num2, quotient, remainder;
    num1=156;
    num2=17;
    // Computes quotient
    quotient = num1 / num2;
    // Computes remainder
    remainder = num1 % num2;
    printf("Quotient = %d\n", quotient);
    printf("Remainder = %d", remainder);
    return 0;
}

Output:

Quotient = 9
Remainder = 3

Example 2 :

Program where we will compute the Quotient and Remainder of 2 numbers given by the users.

Run 
#include<stdio.h>
int main()
{
    int num1, num2, quotient, remainder;
    printf("Enter dividend: ");
    scanf("%d", &num1);
    printf("Enter divisor: ");
    scanf("%d", &num2);
    // Computes quotient
    quotient = num1 / num2;
    // Computes remainder
    remainder = num1 % num2;
    printf("Quotient = %d\n", quotient);
    printf("Remainder = %d", remainder);
    return 0;
}

Input:

Enter dividend: 42
Enter divisor: 8

Output:

Quotient = 5
Remainder = 2

Example 3 :

Program where we will compute the Quotient and Remainder of two number in C using functions.

Run 
#include<stdio.h>
int main()
{
    int num1, num2, quotient, remainder;
    printf("Enter dividend: ");
    scanf("%d", &num1);
    printf("Enter divisor: ");
    scanf("%d", &num2);
    // Computes quotient
    quotient = quo(num1,num2);
    // Computes remainder
    remainder = rem(num1 , num2);
    printf("Quotient = %d\n", quotient);
    printf("Remainder = %d", remainder);
    return 0;
}
int quo(int a, int b)
{
    return a/b;
}
int rem(int n, int m)
{
    return n%m;
}

Input:

Enter dividend: 456
Enter divisor: 3

Output:

Quotient = 152
Remainder = 0
