How will you print numbers from 1 to 100 without using loop? | Set-2

If we take a look at this problem carefully, we can see that the idea of “loop” is to track some counter value e.g. “i=0” till “i <= 100". So if we aren't allowed to use loop, how else can be track something in C language!

It can be done in many ways to print numbers using any looping conditions such as for(), while(), do-while(). But the same can be done without using loops (using recursive functions, goto statement).

Printing numbers from 1 to 100 using recursive functions has already been discussed in Set-1 . In this post, other two methods have been discussed:

1. Using goto statement:

## C++

 `#include ` `using` `namespace` `std; ` ` `  `int` `main() ` `{ ` `    ``int` `i = 0; ` `     `  `begin: ` `    ``i = i + 1; ` `    ``cout << i << ``" "``; ` ` `  `    ``if` `(i < 100) ` `    ``{ ` `        ``goto` `begin; ` `    ``} ` `    ``return` `0; ` `} ` ` `  `// This code is contributed by ShubhamCoder `

## C

 `#include ` ` `  `int` `main() ` `{ ` `    ``int` `i = 0; ` `begin: ` `    ``i = i + 1; ` `    ``printf``(``"%d "``, i); ` ` `  `    ``if` `(i < 100) ` `        ``goto` `begin; ` `    ``return` `0; ` `} `

## C#

 `using` `System; ` ` `  `class` `GFG{ ` ` `  `static` `public` `void` `Main () ` `{ ` `    ``int` `i = 0; ` `    ``begin: ` `        ``i = i + 1; ` `        ``Console.Write(``" "` `+ i + ``" "``); ` ` `  `        ``if` `(i < 100) ` `        ``{ ` `            ``goto` `begin; ` `        ``} ` `} ` `} ` ` `  `// This code is contributed by ShubhamCoder `

Output:

```1 2 3 4 . . . 97 98 99 100
```
2. Using recursive main function:

## C++

 `#include ` `using` `namespace` `std; ` ` `  `int` `main() ` `{ ` `    ``static` `int` `i = 1; ` `     `  `    ``if` `(i <= 100) ` `    ``{ ` `        ``cout << i++ << ``" "``; ` `        ``main(); ` `    ``} ` `    ``return` `0; ` `} ` ` `  `// This code is contributed by ShubhamCoder `

## C

 `#include ` ` `  `int` `main() ` `{ ` `    ``static` `int` `i = 1; ` `    ``if` `(i <= 100) { ` `        ``printf``(``"%d "``, i++); ` `        ``main(); ` `    ``} ` `    ``return` `0; ` `} `

## Java

 `// Java program to count all pairs from both the ` `// linked lists whose product is equal to ` `// a given value ` `class` `GFG  ` `{ ` `    ``static` `int` `i = ``1``; ` ` `  `    ``public` `static` `void` `main(String[] args)  ` `    ``{ ` ` `  `        ``if` `(i <= ``100``) ` `        ``{ ` `            ``System.out.printf(``"%d "``, i++); ` `            ``main(``null``); ` `        ``} ` `    ``} ` `} ` ` `  `// This code is contributed by Rajput-Ji `

## C#

 `// C# program to count all pairs from both the ` `// linked lists whose product is equal to ` `// a given value ` `using` `System; ` ` `  `class` `GFG  ` `{ ` `    ``static` `int` `i = 1; ` ` `  `    ``public` `static` `void` `Main(String[] args)  ` `    ``{ ` `        ``if` `(i <= 100) ` `        ``{ ` `            ``Console.Write(``"{0} "``, i++); ` `            ``Main(``null``); ` `        ``} ` `    ``} ` `} ` ` `  `// This code is contributed by Rajput-Ji `

Output:

```1 2 3 4 . . . 97 98 99 100
```
