Program to print all three digit numbers in ascending order

Last Updated : 10 Feb, 2024

Write a program to print all the three-digit numbers in ascending order.

Output Format:

100 101 102...till 999

Approach: Using for Loop to print all the three Digit Numbers:

Use for loop to iterate from the smallest three-digit number, that is 100 till we reach the largest three-digit number, that is 999 and, in every iteration, print the number. After reaching 999, we will have all the three-digit numbers in ascending order.

Step-by-step algorithm:

Initialize a counter to the smallest 3-digit number i.e. 100.
Run a for loop till the greatest 3-digit number i.e. 999.
For each iteration print the number

Below is the implementation of the above approach:

C++

#include <iostream>
using namespace std;

// Function to print all the three-digit numbers in
// ascending order
void print3DigitNums()
{
    for (int count = 100; count <= 999; count++) {
        cout << count << endl;
    }
}

// Driver code
int main()
{
    cout
        << "All three digit numbers in ascending order: \n";
    print3DigitNums();
}

Java

public class GFG {
    // Function to print all the three-digit numbers in ascending order
    public static void print3DigitNums() {
        for (int count = 100; count <= 999; count++) {
            System.out.println(count);
        }
    }

    // Driver code
    public static void main(String[] args) {
        System.out.println("All three-digit numbers in ascending order: ");
        print3DigitNums();
    }
}

Python3

# Function to print all the three-digit numbers in
# ascending order
def print_3_digit_nums():
    for count in range(100, 1000):
        print(count)

# Driver code
if __name__ == "__main__":
    print("All three digit numbers in ascending order:")
    print_3_digit_nums()

using System;

class GFG
{
    // Function to print all the three-digit numbers in ascending order
    public static void print3DigitNums()
    {
        for (int count = 100; count <= 999; count++)
        {
            Console.WriteLine(count);
        }
    }

    // Driver code
    public static void Main(string[] args)
    {
        Console.WriteLine("All three-digit numbers in ascending order: ");
        print3DigitNums();
    }
}

JavaScript

// Function to print all the three-digit 
// numbers in ascending order
function print3DigitNums() {
    for (let count = 100; count <= 999; count++) {
        console.log(count);
    }
}

// Driver code
console.log("All three digit numbers in ascending order: ");
print3DigitNums();

Output

All three digit numbers in ascending order: 
100
101
102
103
104
105
106
107
108
109
110
111
112
113
114
115
116
117
118

138...

Time Complexity: O(1000) = O(1)
Auxiliary Space: O(1)
