How to remove the first and last character of a string in C++

In this tutorial, we are going to learn about how to remove the first, last character of a string in C++.

Consider, we have the following string.

string color = "white";

Now, we want to remove the first character w and the last character e from the above string.

Removing the first and last character

To remove the first and last character of a string, we can use the built-in substr() function in C++

Here is an example, that removes the first and last character from the color string:

#include <iostream>

using namespace std;

int main()
{
    string color = "white";
    string result = color.substr(1,color.length()-2);
    cout<< result;
    return 0;
}

Output:

"hit"

In the example above, we have passed 1 , color.length()-2 as an arguments to the substr() function. so it begins the extraction at index position 1 and extracts before the last character position (3) of a string.

Note: The substr() function doesn’t modify the original string, instead of it creates a new string with the specified characters.
