C++ program to concatenate a string given number of times
  • Difficulty Level : Easy
  • Last Updated : 17 Oct, 2019

Write a function which returns a new string which is made by concatenating a given string n number of times.

Examples:

Input : str = "geeks"
         n  = 3
Output : str = "geeksgeeksgeeks"
We concatenate "geeks" 3 times

Input : str = "for"
         n  = 2
Output : str = "forfor"
We concatenate "for" 2 times

CPP




// C++ program to concatenate given string
// n number of times
#include <bits/stdc++.h>
#include <string>
using namespace std;
  
// Function which return string by concatenating it.
string repeat(string s, int n)
{
    // Copying given string to temparory string.
    string s1 = s;
  
    for (int i=1; i<n;i++)
        s += s1; // Concatinating strings
  
    return s;
}
  
// Driver code
int main()
{
    string s = "geeks";
    int n = 3;
    cout << repeat(s, n) << endl;;
    return 0;
}


Java




// Java program to concatenate given
// string n number of times
  
class GFG {
      
    // Function which return string by
    // concatenating it.
    static String repeat(String s, int n)
    {
          
        // Copying given string to 
        // temparory string.
        String s1 = s;
      
        for (int i = 1; i < n; i++)
          
            // Concatinating strings
            s += s1; 
      
        return s;
    }
      
    // Driver code
    public static void main(String[] args)
    {
        String s = "geeks";
        int n = 3;
        System.out.println(repeat(s, n));
    }
}
