How do you create a c program whose output is 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5?

Answer 1

To create a C program that outputs the sequence 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5, you can use nested loops. The outer loop will iterate through the numbers from 1 to 5, while the inner loop will print each number a number of times equal to its value. Here's a simple implementation:

#include <stdio.h>

int main() {
    for (int i = 1; i <= 5; i++) {
        for (int j = 0; j < i; j++) {
            printf("%d ", i);
        }
    }
    return 0;
}

This program will print the desired output in a single line.
