Print 1 to 100 without loop using Goto and Recursive-main

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

Last Updated : 02 Mar, 2023

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)

CPP

// CPP program to print "1" 100 times.

// Prints 1 only once
#define a cout<<"1"<<endl;

// Puts "a" 10 times
#define b a a a a a a a a a a

// Puts "b" 10 times
#define c b b b b b b b b b b

int main()
{
  c;
  return 0;
}

Output: 100 times 1.

Time Complexity: O(1). As the program prints "1" only once and it has a constant time complexity of O(1).

Space Complexity: O(1). As no extra space is used in the program, the space complexity is constant and O(1).

Print a number 100 times without using loop, recursion and macro expansion in C?

It is possible to solve this problem using loop or a recursion method. And we have already seen the solution using #define directive (Macro expansion) but what if all three are not allowed? A simple solution is to write the number 100 times in cout statement. A better solution is to use concept of C

Print a character n times without using loop, recursion or goto in C++

Given a character c and a number n, print the character c, n times. We are not allowed to use loop, recursion, and goto. Examples : Input : n = 10, c = 'a'Output : aaaaaaaaaa Input : n = 6, character = '@'Output : @@@@@@ In C++, there is a way to initialize a string with a value. It can be used to p

Print 1 to 100 without loop using Goto and Recursive-main

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: CPP // CPP Program to print 1 to 100 // without loops and recursi

C Program to Print Number series without using any loop

Write a C program for given two number N and K, our task is to subtract a number K from N until number(N) is greater than zero, once the N becomes negative or zero then we start adding K until that number become the original number(N). Note: Not allow to use any loop. Examples : Input : N = 15 K = 5

C Program to print numbers from 1 to N without using semicolon?

How to print numbers from 1 to N without using any semicolon in C. C #include<stdio.h> #define N 100 // Add your code here to print numbers from 1 // to N without using any semicolon What code to add in above snippet such that it doesn't contain semicolon and prints numbers from 1 to N?We stro

How will you print numbers from 1 to 100 without using a loop?

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 loops, how can we track something in the C language?Well, one possibility is the use of 'recursion', provided we use the t

How to print a semicolon(;) without using semicolon in C/C++?

Another interesting question is how can a semicolon be printed without using any semicolon in the program. Here are methods to print ";" : Using printf / putchar in if statement: CPP // CPP program to print // ; without using ; // using if statement #include <stdio.h> int main() { // ASCII val

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

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? Exampl

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
