C++ Exercises: Create a new string from a given string where a specified character have been removed except starting and ending position of the given string

C++ Basic Algorithm: Exercise-33 with Solution

Write a C++ program to create a new string from a given string where a specified character is removed except at the beginning and end.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

// Function to remove the second occurrence of a character from a string
string test(string str1, string c)
{
    // Loop through the string starting from the second-to-last character
    for (int i = str1.length() - 2; i > 0; i--)
    {
        // Check if the character at index 'i' in str1 is equal to the specified character 'c'
        if (str1[i] == c[0])
        {
            // If found, remove the character at index 'i' from the string str1
            str1 = str1.erase(i, 1);
        }
    }

    return str1; // Return the modified string
}

int main() 
{
    // Test cases to remove the second occurrence of a specified character from a string
    cout << test("xxHxix", "x") << endl; 
    cout << test("abxdddca", "a") << endl; 
    cout << test("xabjbhtrb", "b") << endl;

    return 0; // Return 0 to indicate successful completion
}

Sample Output:

xHix
abxdddca
xajhtrb
