How to repeat a string n times in C++

In this tutorial, we are going to learn about how to repeat a string n (number) of times in C++.

In C++, we don’t have a built-in method to repeat a string as we have in Java, Python languages, so we can do it manually by using a for loop.

Repeating a string

To repeat a string n times, we can use the for loop in C++.

Here is an example, that repeats the name string 3 times:

#include <iostream>

using namespace std;

int main() {
  string name = "sai";
  string repeat;

  for (int i = 0; i < 3; i++)
    repeat += name;

  cout << repeat;
  return 0;
}

Output:

"saisaisai"

We can also create a repeat() function like this:

#include <iostream>

using namespace std;

string repeat(string s, int n) {
  string repeat;

  for (int i = 0; i < n; i++)
    repeat += s;

  return repeat;
}

// using the repeat function
int main() {
  cout << repeat("sai", 3);
  return 0;
}
