Breaking the Norms: How to Print 1 to 100 in C Without Loop, Recursion, or Goto Statement

In the world of programming, thinking outside the box can lead to innovative solutions and incredible breakthroughs. One such challenge that many developers face is how to print numbers from 1 to 100 in the C programming language without using traditional methods like loops, recursion, or goto statements. While these methods are commonly used for iterating through numbers, there are alternative ways to achieve the same result.

Method 1: Using Static Variables

One unconventional approach to printing numbers from 1 to 100 in C is by utilizing static variables. By declaring a static variable within a function and incrementing its value with each call, you can effectively print numbers without the need for loops. Here’s an example code snippet to demonstrate this technique:

#include <stdio.h>

void printNumbers() {
    static int num = 1;
    
    if (num <= 100) {
        printf("%d ", num);
        num++;
        printNumbers();
    }
}

int main() {
    printNumbers();
    return 0;
}

In this method, the static variable num retains its value between function calls, allowing us to increment it and print the numbers sequentially without the use of loops or recursion.

Method 2: Using Function Pointers

Another creative way to print numbers from 1 to 100 in C without loops or recursion is by utilizing function pointers. By defining a function that takes a function pointer as an argument, we can call the function recursively until the desired result is achieved. Here’s an example code snippet to demonstrate this technique:

#include <stdio.h>

void printNumber(int num, void (*ptr)(int)) {
    if (num <= 100) {
        printf("%d ", num);
        (*ptr)(num + 1);
    }
}

void printNumbers(int num) {
    printNumber(num, printNumbers);
}

int main() {
    printNumbers(1);
    return 0;
}

By passing the function pointer printNumbers as an argument to the printNumber function, we can achieve the desired outcome of printing numbers from 1 to 100 without using loops, recursion, or goto statements.
