Find if a string contains a character in C++ (boost allowed)

Question

Suppose I have a string and I want to find whether a specific character (like \'|\') is present or not, what is the best and fastest technique to do so? I know string find i

Answer 1

Another way is to use the strchr function on the corresponding c_str string:

if(strchr(str.c_str(), '|'))
{
    \\found
}

Not sure how it compares to std find in terms of speed though...

The position of the found character is

size_t pos = strchr(str.c_str(),'|') - str.c_str();
