Help with program.

**Avestrial** · 05-05-2003

I'm designing a multiple-choice question grading program using functions and 1-dimension arrays. I input: the key to the questions, the number of students taking the exam, the student's answers, followed by the student's names. Then output--the student's name; followed by the number of correct answers; followed by PASS if the number correct is 60% or better or FAIL otherwise.

Now, I can't figure out how I would make the 'key' check the student's answers..and also bout the names, would I have to use file input/output just to store the different names in a text file? if so, how would I do that exactly?

try it, post code, ask a question of exactly what is giving you problems, then we'll be glad to help.

Making the key check the answers is easy, provided you have inputed the key into RAM from a file or manually in the program. Just use comparisons on the students answers and the key's answers:
for(USHORT i=0; i<numofquestions; i++)
{
if(test[i] == key[i])
score += 1; //add one to the score to determine the final score
else
continue;
}
I'm not sure what you mean about the names, but this should get you started

if you are asking the question i think you are asking, which i think that you are, then no, you wouldnt have to use file input/output, unless you wanted them to be there the next time you ran the program. so, if you added a student named john doe this time, for him to be when you next run the program who will need to do file manipolation. if however you only need them there temporarily, then you dont need file manipulation

isnt manipulation a cool word? i think that it is

"would I have to use file input/output just to store the different names in a text file?"

Yes, you need to do file input/output to store the names in a text file.

"if so, how would I do that exactly?"

Code:

#include <fstream>
#include <string>
using namespace std;

int main()
{ 
	string name;
	name ="Sally Johnson";
	
	ofstream outFile("C:\\TestData\\output.txt");
	outFile<<name<<endl;	
	
	return 0;
}
