if(rmv.find(c)!=string::npos) return true; return false; }rmv is declared as a global variable to be noted, so that in can be used in the predicate function. Now for every element c, we have checked whether it is part of the string which contains character to be removed or not....
Remove the Last Character in a String Using thepop_back()Function Thepop_back()is a built-in function in C++ STL that removes the last element from a string. It simply deletes the last element and adjusts the length of the string accordingly. ...

2. Using string::erase functionAnother feasible option to erase the last character from a string is using the string::erase function. This function allows us to erase a part of a string by specifying its position and length. It requires an iterator pointing to the element to be removed ...
This post will discuss how to remove an element from the end of a vector in C++. The solution should effectively reduce the vector size by one.
