C++ program to replace all occurrence of a character in a string

By Aalok Kumar

Hello programmers, Sometimes we need to replace the occurrence of the same characters with a different character in a string, So here is an implementation of that in C++.

In this C++ program,

function reverseStr(std::string str, char c1, char c2); It takes three arguments:

1. std::string str: Original string in which characters are to be replaced.

2. char c1: The character which is to be replaced from the original string str.

3. char c2: New character to be inserted in a place of old character.

The above function returns a new string in which all occurrences of c1 have been replaced by c2.

Here is sample output in the image shown below:
