How to Insert Character at Specific Index in String in C++ - Step by Step Examples

How to Insert Character at Specific Index in String in C++ ?

Answer

To insert a character at a specific index in a string in C++, you can use the `insert()` method of the `std::string` class.


✐ Examples

1 Insert '!' at index 5 in "Hello World"

In this example,

  1. We create a string named str with a value of "Hello World".
  2. We use the insert() method to insert the character '!' at index 5.
  3. Finally, we print the modified string str.

C++ Program

#include <iostream>
#include <string>

int main() {
	std::string str = "Hello World";
	str.insert(5, "!");
	std::cout << str << std::endl;
	return 0;
}

Output

Hello! World
