char *, char[ ], and changing conditions.

[PowerNuke]

Hi all,

My prog is crashing on the following statement:

while ( strcmp( abbrev[loop].initials, product ) != 0 && loop < size )


I get a &quot;illegal&quot; error from windows and the program dies.

char * initials
char product[75]
loop goes from 0 to size (around 150 lines)

I'm thinking that the problem is the char * -vs- char[ ], although there is no syntax error.

For all I know, you can't loop through the struct array in the while statement.

Any ideas or suggestions. I can provide more code if needed.

Thanks in advance.

One reason could be (from the code you've given us) that when an && statement is evaluated if the first term is false the second term is not evaluated (since there's no point, the statement will still evaluate to false). So your 'loop < size' statement is probably not being called in time to stop one more strcmp than is necessary being called causing your program to crash.

Try swapping them round in the while test. ie:
while (loop < size && strcmp( abbrev[loop].initials, product) != 0)

Hope this helps,
