Exercises for beginners : The Standard IO StreamEdit


The following challenge will help to reinforce what you've learned, and give you a springboard from which to start experimenting:

Write a simple program which, when run, asks the user for their name and age, and then displays this back to them. Sample input/output and possible wording are provided below:

Hello. What is your name?
Hello, <name>. How old are you?
<name> is <age> years old.

Solution #1

#include <iostream>

using namespace std;

int main(int argc, char** argv){

  // Get the name
  string name;

  cout<<"Hello. What is your name? "<<endl;

  // Get the age
  int age;

  cout<<"Hello, "<<name<<". How old are you? "<<endl;

  // Show the name and age
  cout<<name<<" is "<<age<<" years old."<<endl;


Solution #2
