Reaching a specific word in a string

Hi I have a string like this:

word1--tab--word2--tab--word3--tab--word4--tab--word5--tab--word6

I need to extract the third word from the string. I thought of reading character by character and getting the word after reading the second tab. But I guess it is inefficient. Can you show me a more specific way please?

assuming "tab" is \t;

std::istringstream str(".....");
std::string temp, word;

str >> temp >> temp >> word;

std::string has the find method which returns an index. You can use 

 find("--", lastFoundIndex + 1)

three times to find the start index of your word, a fourth time for the end index, and then use substr.
