Problem Statement

Write a C program using recursion to print numbers from 1 to N space-separated.

Input Format

An integer N.

Output Format

Print numbers from 1 to N separated by spaces.

Constraints

1 <= N <= 100

Sample Input

5

Sample Output

1 2 3 4 5

Explanation

Recursively call the function with n-1 first, then print the current value on the way back to achieve ascending order.

Starter Code

#include <stdio.h>

void print1ToN(int n) {
    // Write your recursive logic here
}

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        print1ToN(n);
        printf("n");
    }
    return 0;
}

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
