Message: [QUOTE="Udyant Wig, post: 5155067"] | void initialize_bitsource (int16_t *bitsource) | { | int i; | int int_count = minimum_multiple_16 (dimension * dimension); | | for (i = 0; i < int_count; i++) { | *bitsource = (int16_t)(rand () % RAND_MAX); | } | } Note that this code does not work as would be expected (it keeps setting the same integer.) Either add bitsource++; to the loop body, or use this rewrite (using the loop form suggested by Ben Bacarisse): void initialize_bitsource (int16_t *bitsource) { int int_count = minimum_multiple_16 (dimension * dimension); int16_t *ip = bitsource, *end = ip + int_count * sizeof *ip; while (ip < end) { *ip = (int16_t)(rand () % RAND_MAX); ip++; } } [/QUOTE]
