Remove Character from String

Write a C++ program to remove the character at a given position in the string. The given position will be in the range 0..string length -1 inclusive.

Sample Solution:

C++ Code :

#include <iostream>

using namespace std;

// Function to remove a character at index 'n' from the string 'str'
string test(string str, int n)
{
    return str.erase(n, 1); // Erase one character at index 'n' from the string 'str' and return the modified string
}

// Main function
int main() 
{
    cout << test("Python", 1) << endl;  // Output the result of test function with string "Python" and index 1
    cout << test("Python", 0) << endl;  // Output the result of test function with string "Python" and index 0
    cout << test("Python", 4) << endl;  // Output the result of test function with string "Python" and index 4
    return 0;    // Return 0 to indicate successful execution of the program
}

Sample Output:

Pthon
ython
Pythn

Previous: Write a C++ program to create a new string where 'if' is added to the front of a given string. If the string already begins with 'if', return the string unchanged.
Next: Write a C++ program to exchange the first and last characters in a given string and return the new string.
