Thread: Comparing two strings

I know how to compare two strings to see if they are exactly the same, but how can see if one is inside another?

Example:

Code:

string word1 = "one";
string word2 = "oneword";

How can I make an if that checks if word2 has word1 in it?

You can use the find method:

Code:

#include <iostream>
#include <string>

int main()
{
    std::string word1 = "one";
    std::string word2 = "oneword";
    if (word2.find(word1) != std::string::npos)
        std::cout << "Found it!" << std::endl;
}

Thanks

But if word2 is changed to "wordone" it doesn't work anymore, so I assume it has to be at the biginning of the other string. How can I get it to work both ways?

Are you sure you didnt make a typo?
It should still work.

I rewrote the file and now it works... I must have screwed something up last time (it was 4 am!!).

Thanks again.
