In this post, we will learn how to print 1 to 100 using the C++ Programming language.
We will be using the following approaches to print numbers from 1 to 100.
- Using For Loop
- Using While Loop
- Using Do While Loop
So, without further ado, let’s begin this post.
C++ Program to Print 1 to 100 Using For Loop
// C++ Program to Print 1 to 100 Using For Loop
#include <iostream>
using namespace std;
int main(){
int i;
for (i = 1; i <= 100; i++){
cout << i << " ";
}
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
How Does This Program Work?
int i;
In this program, we have declared an integer data type variable named i.
for (i = 1; i <= 100; i++){
cout << i << " ";
}
Then, we used for loop to iterate numbers from 1 to 100. In the for loop, we print the value of i and then increment the value of i by 1.
This process keeps on executing until i <= 100. This gives us all the numbers from 1 to 100.
C++ Program to Print 1 to 100 Using While Loop
// C++ Program to Print 1 to 100 Using While Loop
#include <iostream>
using namespace std;
int main(){
int i = 1;
while (i <= 100){
cout << i << " ";
i++;
}
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 to Print 1 to 100 Using Do While Loop
#include <iostream>
using namespace std;
int main(){
int i = 1;
do{
cout << i << " ";
i++;
} while (i <= 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
