I think operator precedence and associativity is always a favourite one, for instance (without using running it),
int c=55;
int d=823;
int a=++d * c + 99 - 72++
Whats a? - This is just one I have thrown together, but its an illustration of how important it is to know this when writing code - or else you will get bogged down in parenthesis.
Or, heres another one, quite a common newbie missunderstanding, - why does the following code not work.
#include <stdio.h>
char * myfunction();
int main()
{
char * data=myfunction();
printf("%c\n",data[1]);
return 0;
}
char * myfunction()
{
char myarray[]={'h','e','l','l','o'};
return myarray;
}
