 |
|
Hey guys,
When compiling this code (homework I got) I get no error and the code compiles smoothly but when I'm executing the exe file I'm getting this error from vista:
Problem signature:
Problem Event Name: APPCRASH
Application Name: Grade.exe
Application Version: 0.0.0.0
Application Timestamp: 495e8a74
Fault Module Name: Grade.exe
Fault Module Version: 0.0.0.0
Fault Module Timestamp: 495e8a74
Exception Code: c0000005
Exception Offset: 000267ec
OS Version: 6.0.6001.2.1.0.768.3
Locale ID: 1037
Additional Information 1: 026b
Additional Information 2: 2b7432bc90ed02e22ca41bcd76a0c865
Additional Information 3: 7dd6
Additional Information 4: 51623fa4f0f94975881aaf6bdad2573f
The code:
| Code: | #include <iostream>
#include <stdio.h>
using namespace std;
const MAXGRADE = 10;
int main()
{
system("TITLE What's my GPA");
double grades[MAXGRADE];
int numgrade;
double average, total;
cout << "What's my GPA:" << endl;
cout << "--------------" << endl << endl;
for(numgrade = 1; numgrade <= MAXGRADE; numgrade++){
cout << "Enter the " << numgrade << "Th grade: " << endl;
cin >> grades[numgrade];
}
// הצגת הציונים
cout << endl << "The grades are:" <<endl;
cout << "---------------" << endl;
for(numgrade = 1; numgrade <= MAXGRADE; numgrade++){
cout << "The " << numgrade << "Th grade is: " << std::dec << grades[numgrade] <<
endl;
}
// חישוב ההמוצע והצגתו
total = 0;
for(numgrade = 1; numgrade <=MAXGRADE; numgrade++){
total += grades[numgrade];
}
average = (total) / MAXGRADE;
cout << endl << "The average grade is: " << std::dec << average << endl << endl;
getchar();
return 0;
} |
Is it a problem with the code I wrote or something with my computer?

| Code: | | const MAXGRADE = 10; |
No type
| Code: | | // חישוב ההמוצע והצגתו |
try taking these characters out
Other than the first one, works fine one WindowsXP.

Oh lol I haven't noticed that I haven't assigned any type o.O
EDIT: I'm still getting the same mistake even tho I've changed the const type, I don't get any error when compiling so I guess it's my computer..

| (C++) Array elements start at zero, grades[10] has a range of 0-9. Your for loop is going outside these bounds. Begin your loops from 0 or use numgrade-1 when accessing the array.

Maybe it is your settings, or vista.

look carefully at your loops, and watch very carefully how 'grades' is filled.
you are going out of bounds in your array.
edit: god dammit sloppy beat me.

Maybe if you looked up the exception code, you would notice that C0000005 means an access violation.
Change
| Code: |
for(numgrade = 1; numgrade <= MAXGRADE; numgrade++)
|
to
| Code: |
for (numgrade = 1; numgrade [b]<[/b] MAXGRADE; numgrade++)
|
[/code]

That would skip the first grade.
| Code: |
for( numgrade = 0; numgrade < MAXGRADE; numgrade++ )
|
or
| Code: |
for( numgrade = 1; numgrade <= MAXGRADE; numgrade++ ) {
std::cin >> grades[ numgrade - 1 ];
}
