How do I remove everything in a string prior to a specific word in C++?
c++, erase, string, trim
Solution
you can use `find` to find the index to start from, you can use `substr` to select the portion you want to return.
size_t position = str.find("Current");
string newString = phrase.substr(position); // get from position to the end

Problem
SEE FINAL UPDATE FOR SOLUTION This is for school, so I request hints, not blatant answers if possible. I need to take the phrase "My Name current community college" and output "Current Community College" I already have a loop to capitalize current community college. Here is basically what I have up to this point: ``` #include "stdafx.h" #include <iostream> #include <sstream> #include <string> using namespace std; int main() { string phrase = "My Name current community college"; cout << phrase << endl << endl; for (int i = 0; i < phrase.length(); i++) { if (phrase[i] == ' ') { phrase[i + 1] = toupper(phrase[i + 1]); } } return 0; } ``` I've tried using str.find and str.erase but those seem limited in that they can only search for invididual characters. Is there a way I can search for 'Current' (which would be the name of my community college) and just erase everything before the occurrence of that word in the string? UPDATE: Thanks to Sam I Am I was able to accomplish my task, here is what I have now: ``` #include "stdafx.h" #include <iostream> #include <sstream> #include <string> using namespace std; int main() { string phrase = "My Name current community college"; cout << phrase << endl << endl; for (int i = 0; i < phrase.length(); i++) { if (phrase[i] == ' ') { phrase[i + 1] = toupper(phrase[i + 1]); } } size_t pos = phrase.find("Current"); string output = phrase.substr(pos); cout << output << endl << endl; system("PAUSE"); return 0; } ``` I'm obsessive though and just getting an A doesn't accomplish my goal. Is there a way to accomplish this task without having to create a new string, as in, keep my single string but remove everything prior to 'Current'. FINAL UPDATE I figured it out, I don't even need substrings at all. you can use `str.find()` combined with `str.erase()` to just erase everything up until the found word using `size_t pos`: ``` #include "stdafx.h" #include <iostream> #include <sstream> #include <string> using namespace std; int main() { string phrase = "My Name current community college"; cout << phrase << endl << endl; for (int i = 0; i < phrase.length(); i++) { if (phrase[i] == ' ') { phrase[i + 1] = toupper(phrase[i + 1]); } } size_t pos = phrase.find("Current"); //find location of word phrase.erase(0,pos); //delete everything prior to location found cout << phrase << endl << endl; system("PAUSE"); return 0; } ``` You can also replace ``` size_t pos = phrase.find("Current"); phrase.erase(0,pos); ``` with just `phrase = phrase.substr(phrase.find("Current"));` and that works too.
