Small error in C code segment
The following code is supposed to set i to the first occurrence of a positive number in
a[0], a[1], ... , a[n]
or to n+1 if there are no positive numbers; however, the code is incorrect. I need help with what the problem is. Also, I need to write a corrected segment.
Code:for ( i=0; a[i] <= 0 && i <= n; i++ ) ;
For good measure, do "i <= n" before "a[i] <= 0". Otherwise, "i" may be "n+1", and "a[n+1]" is probably undefined behavior. There's no other flaw that I can see.
Devoted my life to programming...
If there are n elements in the array, then the subscript test should be
i < n;
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
