Proverbs Test

Using the table below, write a program that presents these seven proverbs one at a time and asks the user to evaluate them as true or false. The program should then tell the user how many questions were answered correctly, and display one of the following evaluations: Perfect (all seven answers correct), Excellent (5 or 6 correct), You might want to consider taking Psychology 101 (less than 5 correct).

Proverb                             Truth Value

The squeaky wheel gets the grease       True

Cry and you cry alone                           True

Opposites attract                      False

Spare the rod and spoil the child           False

Actions speak louder than words           True

Familiarity breeds contempt                  False

Marry in haste, repent at leisure            True

You must utilize at least two switch statements and three functions (including main) in your solution.

One solution could look like this, yours might be different:

main

       switch statement to present each of the proverbs in order

       function call to func1 to process the answers, returning either true or false

       accumulate correct answer total

       function call to func2 to output the results, pass in total correct

func1

       ask user for answer, return true or false

func2

       switch statement to output results

              7 correct == perfect

              5 or 6 correct == excellent

              < 5 correct == you should take Psychology 101

Answer 1

C++ Program:

#include <iostream>
#include <string>

using namespace std;

string answers[] = {"True", "True", "False", "False", "True", "False", "True"};

//Function checkAnswer
int chkAnswer(string userAnswer, int idx)
{
//Checking answer
if(userAnswer == answers[idx])
return 1;
else
return 0;
}

//Function that produces the result
void produceResult(int score)
{
switch(score)
{
case 7: cout << "\nPerfect\n"; break;

case 6:
case 5:
cout << "\nExcellent\n"; break;

case 4:
case 3:
case 2:
case 1:
case 0: cout << "\nYou should take Psychology 101\n"; break;
}
}

//Main function
int main()
{
string userAnswer;
int i;
int score = 0 ;

//Displaying questions one by one
for(i=1; i<=7; i++)
{
switch(i)
{
case 1: cout << "\n The squeaky wheel gets the grease: ";
break;
case 2: cout << "\n Cry and you cry alone: ";
break;
case 3: cout << "\n Opposites attract: ";
break;
case 4: cout << "\n Spare the rod and spoil the child: ";
break;
case 5: cout << "\n Actions speak louder than words: ";
break;
case 6: cout << "\n Familiarity breeds contempt: ";
break;
case 7: cout << "\n Marry in haste, repent at leisure: ";
break;
}

//Checking user answer
cin >> userAnswer;

if(chkAnswer(userAnswer, i) == 1)
{
score = score + 1;
}
}

//Checking result
produceResult(score);

cout << endl << endl;
return 0;
}
