Question

I have ;

 string  str = "";

in str, I store data is in following form “_ : _, _ ”
“_” can be just a word like “X” or a composition of words like “a sds 23 dsds 1”

I want them parse it to three different string ;

in str       : X:y dfj kd kk,sdd 12 89 ++
string parsed[i] ;
in parsed[0] : X
in parsed[1] : y dfj kd kk
in parsed[2] : sdd 12 89 ++

How can I do that over using c++ std::string features ?

You can split your string using the following std:string methods for example:

size_t index1 = str.find( ":" ) + 1;
size_t index2 = str.find( ",", index1 ) + 1;

std::string sub1 = str.substr (0, index1-1);
std::string sub2 = str.substr (index1, index2-index1-1);
std::string sub3 = str.substr (index2, str.length()-index2);
