Write a C program to print “GfG” repeatedly without using loop, recursion and any control structure?

Last Updated : 11 Oct, 2018

As we all know the concept of printing the given string repeatedly using various loops(for loop,while loop),recursion and some control structure also. But the question is how we will print the given string repeatedly i.e. infinitely without using any loops,recursion and any control structure?

Examples:

Input  : GFG
Output : GFGGFGGFGGFG...(It will print GFG infinitely).

The idea is to use system() to call the program itself. While compiling, we pass the executable file name “test”. We call system(test) which will execute the same program repeatedly, because system is a function which executes extern commands or executable files.

// The program is compiled using -O option 
// to produce output executable file name 
// as "test" 
#include<stdio.h> 
#include<stdlib.h> 
int main() 
{ 
    printf("GFG"); 
    system("test"); 
    return 0; 
} 

Output: It will print GFG infinitely.

How to print a number 100 times without using loop and recursion in C?

It is possible to solve this problem using loop or a recursion method but what if both are not allowed? A simple solution is to write the number 100 times in cout statement. A better solution is to use #define directive (Macro expansion) C/C++ Code // CPP program to print "1" 100 t

Print Substring of a Given String Without Using Any String Function and Loop in C

In C, a substring is a part of a string. Generally, we use string libary functions or loops to extract the substring from a string and then print it. But in this article, we will learn how to print the substring without using any string function or loops. The simplest method for printing a substring

C program to print characters without using format specifiers

As we know that there are various format specifiers in C like %d, %f, %c etc, to help us print characters or other data types. We normally use these specifiers along with the printf() function to print any variables. But there is also a way to print characters specifically without the use of %c form

Our task is to print all numbers from 1 to 100 without using a loop. There are many ways to print numbers from 1 to 100 without using a loop. Two of them are the goto statement and the recursive main. Print numbers from 1 to 100 Using Goto statement Follow the steps mentioned below to implement the

Print 1 to 100 in C++ Without Loops and Recursion

We can print 1 to 100 without using loops and recursion using three approaches discussed below: 1) Template Metaprogramming: Templates in C++ allow non-datatypes also as parameters. Non-datatype means a value, not a datatype. Example: C/C++ Code // CPP Program to print 1 to 100 // without loops and

Write a C program that does not terminate when Ctrl+C is pressed

Write a C program that doesn't terminate when Ctrl+C is pressed. It prints a message "Cannot be terminated using Ctrl+c" and continues execution. We can use signal handling in C for this. When Ctrl+C is pressed, SIGINT signal is generated, we can catch this signal and run our defined signal handler.
