C++ Program to Print 1 to 100

by

Howdy readers, today you will learn how to write a C++ program to print 1 to 100.

This tutorial will print integers from 1 to 100 using the following methods:

  1. Using For Loop
  2. Using While Loop
  3. Using Do While Loop

So, without any delay, let’s begin this tutorial.

C++ Program to Print 1 to 100 Using For Loop

C++ Program

// C++ Program to Print 1 to 100
#include <iostream>
using namespace std;

int main(){
    int num;
    
    for (num = 1; num <= 100; num++){
        cout << num << " ";
    }
    
    return 0;
}

Output

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
C++ Program to Print 1 to 100 Using For Loop

Explanation

    for (num = 1; num <= 100; num++){
        cout << num << " ";
    }

In this program, we have used a for loop to iterate integers from 1 to 100. Within the loop, we print the integer and increase the value of num by 1.

This process keeps on executing until num <= 100. 

C++ Program to Print 1 to 100 Using While Loop

C++ Program

// C++ Program to Print 1 to 100 Using While Loop
#include <iostream>
using namespace std;

int main(){
    int num = 1;
    
    while (num <= 100){
        cout << num << " ";
        num++;
    }
    
    return 0;
}

Output

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100

C++ Program to Print 1 to 100 Using Do While Loop

C++ Program

// C++ Program to Print Numbers From 1 to 100 Using Do While Loop
#include <iostream>
using namespace std;

int main(){
    int num = 1;
    
    do {
        cout << num << " ";
        num = num + 1;
    } while (num <= 100);
    
    return 0;
}

Output

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
