Why doesn't
string x;
std::getline(cin, x)
Do anything? It basically just jumps this line without doing anything at all. I don't understand why, is this outdated or something?

This here works for me:
Code: Select all
#include <iostream>
using std::cin;
using std::string;
int main()
{
string x;
std::getline(cin, x);
std::cout << "You entered: " << x << std::endl;
return 0;
}

Basically im making a school project for the end term, and i figured ill make a program which does what you tell it to do. So i started exeprimenting with some raw code to see if i could get to the point i wanted. This for i got stuck in the main function since following code does not work for me!!
Code: Select all
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
std::string name;
string b;
int x;
cout << "Welcome please enter the password code." << endl;
cin >> x;
if(x==7777){
system("pause");
cout << "What is your name?" << endl;
cin >> b;
cout << "Hello " << b << " what do you want to do today?" << endl;
std::getline(cin, name);
std::cout << name << endl;
system("pause");
}
else{
cout << "Wrong Code" << endl << "press enter to close to application" << endl;
system("pause");
}
return 0;
}
I know very well how badly this is written. I am only trying to get things to work so can write the actual program but id on't know why it jumps the fuction, and others usually spot you mistakes easier!

thanks for help.
