Lab 2 - Basic data types

Complete the following programs. Email both files to my Helios account. Each program is worth 5 points.

1. Write a program that asks the user to enter an integer and then a double. Then echo the entered data to the screen. The interaction should appear as follows:

   Enter an integer: 9
   Enter a double: 5.3
   You entered the integer 9 and the double 5.3.
   

   Save this program as the filename lab2_1.cpp. Compile it using the Helios command

   g++ -o lab2_1 lab2_1.cpp
   

   Run the program a few times and experiment with giving different input such as entering a double instead of an integer for prompt 1 and an integer instead of a double for prompt 2. Also try entering both numbers at once with just a space between them instead of hitting enter after each number. Finally, try this command from your Helios prompt:

   echo "5 1.3" | ./lab2_1

2. Copy the program you just made using the Helios command

   cp lab2_1.cpp lab2_2.cpp
   

   Open lab2_2.cpp in pico or vi and do the following modifications. Remove the "You entered" line and instead output the following calculations, one output per line:
   1. The integer divided by the integer 10.
   2. The double divided by the integer 10.
   3. The integer divided by the double.
   The output should appears as follows:

   Enter an integer: 9
   Enter a double: 5.3
   The value of 9 / 10 is 0.
   The value of 5.3 / 10 is 0.53.
   The value of 9 / 5.3 is 1.69811.
   

   Compile using the Helios command

   g++ -o lab2_2 lab2_2.cpp
   

   Notice the difference between integer division and double division.
