C Program to Compute Quotient and Remainder

Given two numbers A and B. The task is to write a program to find the quotient and remainder of these two numbers when A is divided by B.

Examples: 

Input: A = 2, B = 6
Output: Quotient = 0, Remainder = 2

Input: A = 17, B = 5
Output: Quotient = 3, Remainder = 2

1. Using Division and Modulo Operator

In the below program, to find the quotient and remainder of the two numbers, the user is first asked to enter two numbers. The inputs are scanned using the scanf() function and stored in the variables A and B. Then, the variables A and B are divided using the arithmetic operator / to get the quotient as the result stored in the variable quotient; and using the arithmetic operator % to get the remainder as the result stored in the variable remainder. 

Below are the programs to find the quotient and remainder of two numbers: 

C++

// C++ program to find quotient
// and remainder of two numbers
#include <iostream>
using namespace std;

// Driver code
int main()
{
    int A = 17, B = 5;

    // Ask user to enter the two numbers
    cout << "Enter two numbers A and B: ";

    // Read two numbers from the user || A = 17, B = 5
    cin >> A >> B;

    // Calculate the quotient of A and B using '/' operator
    int quotient = A / B;

    // Calculate the remainder of A and B using '%' operator
    int remainder = A % B;

    // Print the result
    cout << "Quotient when A / B is: " << quotient << endl;
    cout << "Remainder when A / B is: " << remainder;
}

C

// C program to find quotient
// and remainder of two numbers
#include <stdio.h>

// Driver code
int main()
{
    int A, B, quotient = 0, remainder = 0;

    // Ask user to enter the two numbers
    printf("Enter two numbers A and B : \n");

    // Read two numbers from the user || A = 17, B = 5
    scanf("%d%d", &A, &B);

    // Calculate the quotient of A and B using '/' operator
    quotient = A / B;

    // Calculate the remainder of A and B using '%' operator
    remainder = A % B;

    // Print the result
    printf("Quotient when A/B is: %d\n", quotient);
    printf("Remainder when A/B is: %d", remainder);

    return 0;
}

Java

// Java program to find quotient
// and remainder of two numbers
import java.io.*;
import java.util.Scanner;

class GFG {

  public static void main (String[] args) {

    Scanner input = new Scanner(System.in);
    int A = input.nextInt();
    int B= input.nextInt();
    int
    quotient = 0, remainder = 0;

    // Ask user to enter the two numbers
    System.out.println("Enter two numbers A and B :
                       "+" "+ A+" "+ B);

    // Read two numbers from the user || A = 17, B = 5

    // Calculate the quotient of A and B using '/' operator
    quotient = A / B;

    // Calculate the remainder of A and B using '%' operator
    remainder = A % B;

    // Print the result
    System.out.println("Quotient when A/B is: "+ quotient);
    System.out.println("Remainder when A/B is: "+ remainder);
    }
}

Python3

# Python3 program to find quotient
# and remainder of two numbers

if __name__=='__main__':

    quotient = 0
    remainder = 0


#Read two numbers from the user || A = 17, B = 5
    A, B = [int(x) for x in input().split()]

#Calculate the quotient of A and B using '/' operator

Javascript

<script>
    // Javascript program to find quotient
    // and remainder of two numbers


    var A, B;

    // Ask user to enter the two numbers
    document.write("Enter two numbers A and B: ");

    // Read two numbers from the user || A = 17, B = 5

    A = parseInt(prompt());
    B = parseInt(prompt());

    // Calculate the quotient of A and B using '/' operator
    var quotient = Math.floor(A / B);

Output

Enter two numbers A and B: Quotient when A / B is: 3
Remainder when A / B is: 2

The complexity of the above method

Time Complexity: O(1)

Auxiliary Space: O(1)

2. Using Loops

Below is the C program to find the quotient and remainder using loops:

C

// C program to find quotient and
// remainder
#include <stdio.h>

// Driver code
int main()
{
    int A = 17, B = 5;

    int quotient = 0;

    // Initializing the loop
    while (quotient * B <= A)
        quotient++;

    // Decrementing 1 because we came
    // one step forward
    quotient--;

    int remainder = A - (B * quotient);

    printf("Quotient when A/B is: %d\n", quotient);
    printf("Remainder when A/B is: %d", remainder);
    return 0;
}

C++

// C++ program to find quotient
// and remainder
#include <iostream>
using namespace std;

// Driver code
int main()
{
  int A = 17, B = 5;

  int quotient = 0;

  // Initializing the loop
  while(quotient * B <= A)
    quotient++;

  // Decrementing 1 because we came
  // one step forward
  quotient--;

  int remainder= A - (B * quotient);

  cout << "Quotient when A / B is: " <<
           quotient << endl;
  cout << "Remainder when A / B is: " <<
           remainder;
  return 0;
}

Java

// Java program to find quotient
// and remainder of two numbers
import java.io.*;
import java.util.Scanner;

class GFG {

  public static void main (String[] args) {

    int A = 17, B = 5;
    int quotient = 0;

    // Initializing the loop
    while(quotient * B <= A)
      quotient++;

    // Decrementing 1 because we came
    // one step forward
    quotient--;

    int remainder= A - (B * quotient);

    // Print the result
    System.out.println("Quotient when A/B is: " +
                       quotient);
    System.out.println("Remainder when A/B is: " +
                       remainder);
  }
}

    int quotient = find_quotient(A, B);
    int remainder=find_remainder(A, B);
    cout << "Quotient when A / B is: " <<
             quotient << endl;
    cout << "Remainder when A / B is: " <<
             remainder;
