remove () not working c++

To remove parentheses from a string in C++, you can follow these steps:

1. Initialize a string variable to store the input string without parentheses.
2. Iterate through each character in the input string.
3. Check if the current character is an opening parenthesis "(" or a closing parenthesis ")".
4. If it is not a parenthesis, append the character to the new string variable.
5. Repeat steps 3 and 4 for each character in the input string.
6. After iterating through all the characters, the new string variable will contain the input string without parentheses.

Here is an example code snippet that demonstrates this process:

#include <iostream>
#include <string>

std::string removeParentheses(const std::string& input) {
    std::string result;
    for (char c : input) {
        if (c != '(' && c != ')') {
            result += c;
        }
    }
    return result;
}

int main() {
    std::string input = "(Hello) World!";
    std::string output = removeParentheses(input);
    std::cout << "Input: " << input << std::endl;
    std::cout << "Output: " << output << std::endl;
    return 0;
}

This code defines a function removeParentheses that takes an input string and returns a new string with parentheses removed. The main function demonstrates the usage of this function by providing an example input string "(Hello) World!". The output of the program will be:

Input: (Hello) World!
Output: Hello World!
