C ++程序连接字符串给定次数

编写一个函数，该函数返回一个新字符串，该字符串由给定字符串连接 n 次而成。
例子：

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 
#include 
using namespace std;
 
// Function which return string by concatenating it.
string repeat(string s, int n)
{
    // Copying given string to temporary string.
    string s1 = s;
 
    for (int i=1; i


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
        // temporary string.
        String s1 = s;
     
        for (int i = 1; i < n; i++)
         
            // Concatenating 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));
    }
}

Python3
# Python 3 program to concatenate
# given string n number of times
 
# Function which return string by
# concatenating it.

    # Copying given string to
    # temporary string.
    s1 = s
 
    for i in range(1, n):
         
        # Concatenating strings
        s += s1
 
    return s
 
# Driver code
s = "geeks"
n = 3
print(repeat(s, n))
