How to find char* in a vector of string

I have a char* t, that I want to find it in a vector of strings. For example, the char *t points to "abc", and my vector has the same "abc" as a string.

This isn't really a new answer in itself, just some demo code for what @Luchian posted:

#include <string>
#include <algorithm>
#include <sstream>
#include <iostream>

int main() { 

    std::vector<std::string> data;

    for (int i=0; i<10; i++) {
        std::ostringstream b;
        b << "String " << i;
        data.push_back(b.str());
    }

    auto pos = std::find(data.begin(), data.end(), "String 3");

    std::cout << pos-data.begin();

    return 0;
}

At least when I run this, it appears to find the string (it prints out 3).

Use std::find - it will implicitly convert the char* to a std::string.

auto foundIterator = std::find(vec.begin(), vec.end(), t);

If the element is not in the vector, then foundIterator will be equal to vec.end().
