This should have been my second post, but I idiotically posted up source code of a "complicated" application for new learners. This post will be about basic input and output in c++. here would be an example of a Hello program:

Code:

#includes <iostream>
using namespace std;//this is for the cin and cout functions

int main()
{
    char x[128];//edited 10:04 am 8/22/2012
    cout << "What is your name?" << endl;//this is the output
    cin >> x;//this is the input
    cout << "Hello " << x << "!" << endl; //this is the result
    system("PAUSE");//this lets you review the result
    return 0;// returns positive if it completes
}

And that is a basic Hello program. In the next tutorial we will be covering the use of variables.

You shouldn't use an array of char unless you know all the space is going to be taken up or that not many left over spot. You are using extra space in memory, with the empty slots of the array. In your case all you should really do is change the size of your array to 20, for input of first and last names at the most.

Code:


#include <iostream> //input/output stream
#include <string> //string
#include <windows.h> //windows functions if not using vs c++

using namespace std; //function shorteners using namespace

int main(void) {
     string uName; //user name
    
     cout << "What is your name: ";
     cin >> uName; //store name inside uName

     cout << "Hello " << uName << "!" << endl; //output
     Sleep(3*1000); //wait 3 seconds before ending

     return 0;
}


best way to do this for mem purposes
