Let's say I have std::string temp as:
std::string temp = "{abc,def}";I want the temp to contain "abc,def", i.e. remove the '{' and '}' from beginning and end of the temp.
So I wrote:
temp = temp.substr( 1, temp.length() - 1 );However after executing it, the temp contains "abc,def}".
What am I missing? Is there an easier way to do what I'd like?

temp = temp.substr( 1, temp.length() - 1 ); - as mentioned in the comments, it gets substring on 1 char shorter, but you want to remove 2 characters, so the proper code: temp = temp.substr( 1, temp.length() - 2 );.
This constructs a new string and is not optimal for long strings. A better inplace solution:
temp.erase(0, 1); // or temp.erase(temp.begin()) temp.pop_back();
