Having come to realize that this is a homework problem, I would of course
be glad to.
The original program:
#include<cstdio>
int main()
{
int a[100], n;
freopen("input.txt", "r", stdin);
scanf("%d",&n);
for(int i=1; i<=n; i++)
scanf("%d",&a[i]);
return 0;
}
This guy doesn't know C very well, either.
First, "scanf" was deprecated over five years ago.
And reopening "stdin" is rarely done, although
it is possible.
Second, there's a buffer overflow. "n" is obtained
from external input, then used to control the "for"
statement. If N is >= 99, there will be a buffer
overflow on "a". Also, starting to fill "a" from 1
looks like an error.
Third, the program doesn't actually do anything.
There's no output.
It looks like this approach to C came from
