hey guys

id like to know how i can read a string from a certain point in c++. for example

Code:

int a=6;
string str="hey guys i need help";
string buffer;
*funtion to read string str starting from str[a] into string buffer*;
cout << buffer;

output would be "uys i need help".

is there anyway to do this?

thanks in advance

I'd use the substr function, i.e.,

Code:

  std::string buffer= str.substr(a-1);
  std::cout << buffer << std::endl;

You need to subtract 1 because str[6] == 'y'.
