C++ Program to Count Total Number of Notes in Given Amount

In this program, we will learn how to count the total number of notes in the given amount using C++ Programming language.

The user is asked to enter an amount, then this program will calculate the total number of notes that could make up that amount.

So, without further ado, let’s begin this tutorial.

C++ Program to Count Total Number of Notes in Given Amount

// C++ Program to Count Total Number of Notes in Given Amount
#include <iostream>
using namespace std;

int main(){
    int i, amount; 
    int arr[9] = {2000, 500, 100, 50, 20, 10, 5, 2, 1};
    
    // Asking for input
    cout << "Enter the amount: ";
    cin >> amount;
    
    // Calculating total number of notes
    for (i = 0; i < 9; i++){
        cout << arr[i] << " Note: " << amount / arr[i] << endl;
        amount = amount % arr[i];
    }
    return 0;
}

Output

Enter the amount: 18256
2000 Note: 9
500 Note: 0
100 Note: 2
50 Note: 1
20 Note: 0
10 Note: 0
5 Note: 1
2 Note: 0
1 Note: 1

How Does This Program Work ?

    int i, temp, amount; 
    int arr[9] = {2000, 500, 100, 50, 20, 10, 5, 2, 1};

In this program, we have declared some int data type variables named i, amount and arr.

    // Asking for input
    cout << "Enter the amount: ";
    cin >> amount;

Then, the user is asked to enter the amount.

   // Calculating total number of notes
    for (i = 0; i < 9; i++){
        cout << arr[i] << " Note: " << amount / arr[i] << endl;
        amount = amount % arr[i];
    }

Now, we calculate the total no. of notes using a simple for loop function.

C++ Program to Count Total Number of Notes Using Functions

// C++ Program to Count Total Number of Notes in Given Amount Using Functions
#include <iostream>
using namespace std;

int CountNotes(int amount){
    int i; 
    int arr[9] = {2000, 500, 100, 50, 20, 10, 5, 2, 1};
    
    // Calculating total number of notes
    for (i = 0; i < 9; i++){
        cout << arr[i] << " Note: " << amount / arr[i] << endl;
        amount = amount % arr[i];
    }
}

int main(){
    int amount;
    
    // Asking for input
    cout << "Enter the amount: ";
    cin >> amount;
    
    CountNotes(amount);
    return 0;
}

Output

Enter the amount: 7777
2000 Note: 3
500 Note: 3
100 Note: 2
50 Note: 1
20 Note: 1
10 Note: 0
5 Note: 1
2 Note: 1
1 Note: 0

C++ Program to Count Total Number of Notes Using If Else Statement

// C++ Program to Count Total Number of Notes Using If Else Statement
#include <iostream>
using namespace std;

int main(){
    int amount;
    int note1, note2, note5, note10, note20, note50, note100, note200, note500, note2000;
    note1 = note2 = note5 = note10 = note20 = note50 = note100 = note200 = note500 = note2000 = 0;
    
    // Asking for input
    cout << "Enter the amount: ";
    cin >> amount;
    
    if (amount >= 2000){
        note2000 = amount / 2000;
        amount -= note2000 * 2000;
    }
    if (amount >= 500){
        note500 = amount / 500;
        amount -= note500 * 500;
    }
    if (amount >= 200){
        note200 = amount / 200;
        amount -= note200 * 200;
    }
    if (amount >= 100){
        note100 = amount / 100;
        amount -= note100 * 100;
    }
    if (amount >= 50){
        note50 = amount / 50;
        amount -= note50 * 50;
    }
    if (amount >= 20){
        note20 = amount / 20;
        amount -= note20 * 20;
    }
    if (amount >= 10){
        note10 = amount / 10;
        amount -= note10 * 10;
    }
    if (amount >= 5){
        note5 = amount / 5;
        amount -= note5 * 5;
    }
    if (amount >= 2){
        note2 = amount / 2;
        amount -= note2 * 2;
    }
    if (amount >= 1){
        note1 = amount / 1;
        amount -= note1 * 1;
    }
    
    // Displaying output
    cout << "Total number of notes: " << endl;
    cout << "2000 = " << note2000 << endl;
    cout << "500 = " << note500 << endl;
    cout << "200 = " << note200 << endl;
    cout << "100 = " << note100 << endl;
    cout << "50 = " << note50 << endl;
    cout << "20 = " << note20 << endl;
    cout << "10 = " << note10 << endl;
    cout << "5 = " << note5 << endl;
    cout << "2 = " << note2 << endl;
    cout << "1 = " << note1 << endl;
    return 0;
}

Output

Enter the amount: 5454
Total number of notes: 
2000 = 2
500 = 2
200 = 2
100 = 0
50 = 1
20 = 0
10 = 0
5 = 0
2 = 2
1 = 0
