For this project, you will make a program that will test the user's proficiency at solving different types of math problems. The program will be menu driven. The user will select either addition, subtraction, multiplication or division problems. The program will then display a problem, prompt the user for an answer and then check the answer displaying an appropriate message to the user whether their answer was correct or incorrect. The user will be allowed 3 tries at each problem. The program will also keep statistics on how many problems were answered correctly.

At this point you should have a working copy of the program that displays practice programs for addition, subtraction, multiplication and division.

This week you will add functions to allow the user to select problems of varying degrees of difficulty and also keep statistics on number of correct answers vs. total number of problems attempted.

So now let's add the code for the remaining functions:

We'll start by inserting code to ask the user if they want to see problems that are easy, medium or difficult. prompting them to enter 'e' for easy, 'm' for medium or 'd' for difficult and we'll this is right after they have selected the type of problems they want. We will also add a validation loop that will check to see if they entered a correct response (e,m, or d).

Easy - problems using numbers 0 thru 10
Medium - problems 11 thru 100
Difficult - problems 100 - 1000

Here's some code to get you started on the "difficulty level."
if( difficultyLevel == 'E')
{
num1=rand()%10+1;
num2=rand()%10+1;
}
else
if (difficultyLevel == 'M')
{num1=rand()%100+1;
num2=rand()%100+1;
}
else
{ num1=rand()%1000+1;
num2=rand()%1000+1;}

Use an "if" statement to check the difficulty and generate the random numbers.

Statistics:

Create two variables ttlProblems and correctAnswers. Every time the user answers a problem add 1 to ttlProblems and every correct answer add 1 to correctAnswers. We'll display the total number of problems and correct answers as well as the percent correct after the user has selected the exit option on the main menu.
