I wanted to retrieve all the values/words before '='
Ex:
A = my first variable, I wanted to get all the strings;
var2 = I wanted to get this variable also;
var3 = jcdksjfckjdsckjdscjkdsbckjdsncjsjd;
Now I wanted to retrieve all the variables (A, var2, var3)
from the above text (c++ std::string).
Update: One possible way is
vector<string> myClass::getVariablesFromDescription(string f_description)
{
vector<string> l_variables;
stringstream l_desc;
l_desc << f_description;
string l_temp;
string l_prvStr = string();
for(int i=0; l_desc >> l_temp ; i++ )
{
if(l_temp == string("="))
{
l_variables.push_back(l_prvStr);
}
l_prvStr = l_temp;
}
return l_variables;
}
You can create a new string, start copying the original byte-by-byte there and stop when you detect a '='.
string example = "var69 = asdfghjkl";
string var_name;
for(int i=0; i<example.size(); i++)
{
if(example[i] == '=') break;
var_name += example[i];
}
I cannot comment yet, but you asked for a hint.
find returns a position of where the = sign is. You also know you started at 0. Then you can get the string from 0 to position and just copy that out.
