Hello, I'm trying to use a
remove_if
In c ++ however when it arrives at the input part I can not determine for it to detect if the string I'm pointing has a char. Here is my code:
temp.erase(remove_if(temp.begin(), temp.end(), "("), temp.end());
temp is a string.
The remove_if gets 3 parameters, the start and end iterators, and a function that takes a parameter and returns a bool . In this case you can pass the function using its name as if it were a variable.
Follow the code below:
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
bool isParenthesis (char c) {
return c == '(';
}
int main () {
string temp = "123(456";
temp.erase(remove_if(temp.begin(), temp.end(), isParenthesis));
cout << temp;
cout << endl;
return 0;
}
You can also see an example in documentation .
