I'm not very familiar with long values, other than it being a form of numbers like integers, so:
is the long value 2L equate to simply 2 base type long, or something more?
if so then wouldn't this be the same:
Code:long var; var = 2L; var = 2; //same thing?
i see there are a number of page views. why hasn't anyone responded?
Some differences would be noticeable on a platform that has different sized ints and longs when the constant is used in an expression.>i see there are a number of page views. why hasn't anyone responded?Code:#include <stdio.h> int main(void) { long a = 32000 * 4, b = 32000 * 4L, c = 32000L * 4, d = 32000L * 4L, e; printf("sizeof(2) = %lu\n", (long unsigned)sizeof(2)); printf("sizeof(2L) = %lu\n", (long unsigned)sizeof(2L)); printf("a = %ld, b = %ld, c = %ld, d = %ld\n", a, b, c, d); e = 1 << 16; printf("e = %ld\n", e); e = 1L << 16; printf("e = %ld\n", e); return 0; } /* my output sizeof(2) = 2 sizeof(2L) = 4 a = -3072, b = 128000, c = 128000, d = 128000 e = 0 e = 65536 */
Don't do this (see #5).

7. It is easier to write an incorrect program than understand a correct one.
40. There are two ways to write error-free programs; only the third one works.*
thanks. ;-)

Quzah.
Hope is the first step on the road to disappointment.
