Code:okay i feel like such a newb why the -1 in the for loops?
for (count = 0; count<=size-1; count++)
{
cin>> your_answers[count];
}
and also he told us to use 21 because we have to include the null terminator or some bull........

Code:okay i feel like such a newb why the -1 in the for loops?
for (count = 0; count<=size-1; count++)

Here is some updated code:
Code:#include <iostream>
using namespace std;
int main()
{
int count, correct = 0;
const int size = 20;
char your_answers[size];
char answers[size] = {'b','d','a','a','c','a','b','a','c','d','b','c','d','a','d','c','c','b','d','a'};
cout<< " Please enter the students answers. \n" ;
for (count = 0; count<=size-1; count++)
{
cin >> your_answers[count];
while(true)
{
if (your_answers[count] == 'a' || your_answers[count] == 'b' || your_answers[count] == 'c' || your_answers[count] == 'd')
break; //Break out of while loop.
else
{
cout << "(" << your_answers[count] << ") Your answer is not an appropriate one. Please try again." << endl;
cin >> your_answers[count];
}
}
}
for (count=0; count<=size-1;count++)
{
if (answers[count] == your_answers[count])
correct += 1; //If they got this one right, then add one to 'correct'.
}
if(correct >= 15) //They got 15 right
cout << "\nYou passed the test. Congratulations." << endl;
else
cout << "\nYou're a failure." << endl;
cout << "You got " << correct << " out of 20 correct." << endl;
cout << endl; //Make a new line.
for (count = 0; count<=size-1; count++)
{
cout << "Correct Answer: " << answers[count] << " | Your answer: " << your_answers[count];
if (answers[count] == your_answers[count]) //It's correct;
cout << " [CORRECT]." << endl;
else
cout << " [WRONG]." << endl;
}
system("PAUSE");
return 0;
}
Code:#include <iostream>
#include <string>
using namespace std;
int main()
{
int count, correct = 0, incorrect = 0;
const int size = 20;
char your_answers[size];
char answers[size] = {'b','d','a','a','c','a','b','a','c','d','b','c','d','a','d','c','c','b','d','a'};
cout<< " Please enter the students answers. \n" ;

system ("pause");
return 0;
}
okay so this is what i got so far, i need to find a way to show which answers i got wrong, i.e. if number[1] is wrong display number[1] of array
and i still cant figure out that damned validation
this is good, but i cant use (true)
im limited in the crap i can use so if there is another simpler way of validation i would appreciate if you could help me
Flaug, you should give pointers, not complete homework assignments.
its not a homework assignment,
my teacher expects us to learn loops in a week and didnt cover do's and fors,
im goin over a few assignments and tryin to get them but i need alot of help
he told us to learn do's for's while's, so im learning whats in those chapters
i also appreciate all the help man thank you so much
Hogwash. It's homework.
Code:well either way sebastianinininnininininininininininininiininininiininiiinininin
do you know what i should look into if i want to validate my answers without using (true)
all i can think of is
if (your_answers != 'a' ||' b' ||'c'||'d')
{
cout<< "incorrect answer, please enter a,b,c, or d. \n"
cin>> your_answers[count]
}
>> do you know what i should look into if i want to validate my answers without using (true)
Well, considering that the code you posted is both logically broken and won't even compile, I'd suggest a decent book.
Code:#include <iostream>
#include <string>
using namespace std;
int main()
{
int count, correct = 0, incorrect = 0;
const int size = 20;
char your_answers[size];
char answers[size] = {'b','d','a','a','c','a','b','a','c','d','b','c','d','a','d','c','c','b','d','a'};
cout<< " Please enter the students answers. \n" ;
for (count = 0; count<=size-1; count++)
{
cin>> your_answers[count];
}
for (count=0; count<=size-1;count++)
{
if (answers[count] == your_answers[count])
correct += 1;
}
for (count=0; count<size;count++)
{
if (answers[count] != your_answers[count])
incorrect += 1;
}
if(correct >= 15)
cout << "You passed the test. Congratulations." << endl;
else
cout << "You're a failure." << endl;
cout << "You got " << correct << " out of 20 correct." << endl;
cout<< " You got " << incorrect<< " out of 20 wrong. "<<endl;
cout << endl;
for (count = 0; count<=size-1; count++)
{
cout << "Correct Answer: " << answers[count] << " | Your answer: " << your_answers[count];
if (answers[count] == your_answers[count])
cout << " [CORRECT]." << endl;
else
cout << " [WRONG]." << endl;
}
system ("pause");
return 0;
}
and my output is
Please enter the students answers.

You passed the test. Congratulations.
You got 19 out of 20 correct.
You got 1 out of 20 wrong.

Press any key to continue . . .
now i still need good output validation an i dont know how to do it
Code:while (your_answers != 'a', 'b', 'c', 'd')
{
cout<< "Your answer of "<< your_answers[count]<<" is invalid, please select A,B,C or D. \n";
cin>> your_answers[count];
}
i need something along these lines but i cant figure it out
I don't see a shred of code that shows you *trying* to validate the input. Perhaps a combination of tolower() and isalpha() might be useful?
Also, this sort of thing won't work:
>> if (X != 'a' ||'b')
Since it's identical to:
if (X != 'a' ||'b' != 0)
You'll need to compare each value with X (but using && instead of ||, obviously).
thank you sir ill see what i come up with
also i dont know what the crap isalpha and tolower are, this is an intro level class and im tryin to teach myself arrays and loops ya know
