[DUG] Converting some code from C

I'm converting some code from some ugly C. The code defines one particular array, and a constant like this: static float snorm[169]; static float *p = snorm; and then later has an assignment: *snorm = 1.0; and then again later (n is an integer iterator): *(snorm+n) =

Re: [DUG] Converting some code from C

Pointers and arrays are essentially equivalent in c. And pointer arithmatic works like array indexation, so ... *(snorm+n) = *(snorm+n-1)*(float)(2*n-1)/(float)n; and snorm[n] = *(snorm+n-1)*(float)(2*n-1)/(float)n; and snorm[n] = snorm[n-1]*(float)(2*n-1)/(float)n; are all equivalent

[DUG] Dumb question

Hi All This may be a dumb question but... How do I assign an Int64 variable to a Int64 field in a DB. Usually we use FieldByName('sdf').AsInteger := xx to assign values. What is the appropriate way to do this? Rob MartinSoftware Engineerphone 03 377 0495fax 03 377 0496 web

Re: [DUG] Converting some code from C

OK, thanks for that. I had assumed that they were equivalent, but the useage in the original code is mixed (sometimes pointer sometimes array indexed) so I thought I'd better check. Cheers, Phil. - Original Message - From: Terry [EMAIL PROTECTED] To: NZ Borland Developers Group - Delphi

Re: [DUG] Converting some code from C

** is double indirection. Pointer to a pointer. If you have ... char * p; then *p is a char, p is a pointer to a character. If you have... char ** p; then **p is a character, *p is a pointer to a character, p is a pointer to a pointer to a character. All parameters in C are passed by

I'm guessing: the XL viewer is just that - data that has previously be calculated can be seen while values that need to be calculated are not available. It's what I would expect from MS. Daryl Marsden Project Management Analyst Environment Canterbury P O Box 345 Christchurch Visit us online
