Lab Exercise on C++ Basic I/O

• Get a copy of the sampleio.cpp

  The purpose of the program is to demonstrate how to INPUT data from the standard input device (the keyboard) and how to OUTPUT data to the standard output device (screen).

• Compile and run this C++ program. Modify the program by changing the code so that you are able to input two integer numbers from the keyboard (i.e. You need to prompt the user input data from keyboard so that your input is user interactive.) and then print out their sum to the screen. Your output should looks like the following:

  Please enter a number: 23
  Please enter another number: 5
  The sum of the two numbers is : 28
  

• Compile and run this modified C++ program.

• Capture the program output under the name:lab3-1.doc
  Show the content of lab3-1.doc to your lab instructor

  
  Hint: To compile in hercules, enter CC sampleio.cpp -o sampleio
  To run it, enter sampleio
