erasing or splitting strings

[AdRock]

I have some code i've written and i need to splita string and assign the results to 2 variables type and value

The first part of the string up to the : would the type and what is after the : would be the value

When i output the variables i get NAME as the type variable but the value variable is empty. Is this becuase the temp variable has already been erased? If i take out the type erase, the value erase works but it won't do both

Would it be best to split the string on the :

string temp = "NAME: name";

std::size_t pos;
pos= temp.find(":");
				
if(pos != string::npos)
{
	int len = temp.size();
	
	string type= temp.erase(pos, (len-pos));
	string value = temp.erase(0, pos+2);
}

you want to use the substr() method, not erase(). And delete line 8 because length isn't needed (unless you want to use it somewhere else).

string type = temp.substr(0, pos);
string value = temp.substr(pos+1);

I don ot think erase() would do the trick.. why not use strtok()?

#include<iostream>
#include<string>
#include<cstring>
using namespace std;
int main()
{
 char* temp = "NAME: name";
 char* pch;
 pch=strtok(temp," :");
 while(pch!=NULL){
 cout<<pch<<endl;
 pch=strtok(NULL," :");
 }
 return 0;

Please, If this helped,mark this thread as solved AND add to my reputation points...Thanks!!

Bad idea. strtok() will crash the program you posted because it will attempt to change the string literal.
