Remove the Last Character from a String in C++

To remove the last character from a string, we can use the pop_back() function which is used to pop the character that is placed at the last in the string and finally print the string after removal.

C++ Program to Remove the Last Character from a String

The below example demonstrates the use of the pop_back() function to remove the last character from the string.

Before deletion string is : Hello,Geeks
String after removing the last character: Hello,Geek

Note: pop_back() function works in-place meaning the modification is done in the original string only which results in a reduction of the size of the original string by one.

We can also use the erase() and resize() function to remove the last character from a string.
