Remove spaces from std::string in C++

Question

What is the preferred way to remove spaces from a string in C++? I could loop through all the characters and build a new string, but is there a better way?

Answer 1

You can use this solution for removing a char:

#include 
#include 
using namespace std;

str.erase(remove(str.begin(), str.end(), char_to_remove), str.end());
