C++ Exercises 3

1. Write a program that opens a file and counts the whitespace-separated words in that file.

2. Write a program that opens a (text) file, and displays the contents of that file one line at a time. After a line has been displayed, the program should wait for the user to press the key before displaying the next line in the file.

3. Write a program that uses two nested for loops and the modulus operator (%) to detect and print the prime numbers from 1 to 10,000. (Prime numbers are natural numbers that are not evenly divisible by any other number except for themselves and one). Display all the primes found.

4. Write a program that creates an array of 100 string objects. Fill the array by having your program open a (text) file and read one line of the file into each string until you have filled the array. Display the array using the format line #: , where # is the actual line number (you can use the array counter for this value) and is the stored string.

5. Create a makefile for one of the exercises in this assignment (your choice) that allows the user to type make for a production build of the program and make debug for a build of the program that includes debugging information.
