i wanted to start learning and coding .c again
but i dunno the many types etc
and i hate the texts around like guide this and shitt that

alexmb7 2022-07-30 10:08:40

say i wanna do a small awk

alexmb7 2022-07-30 10:08:57

that is vars and strings and functions

alexmb7 2022-07-30 10:10:14

i have big probs with memory alloc
i wanna imolent exact len string assignments ( as practically every str is known len ( not before but at def ) ) and i dunno at all to do this in .c

alexmb7 2022-07-30 10:12:14

i long years ago did some scanner
but i didnt know back then about ‘volatile’ that i can with it define variable len array as like set by user

alexmb7 2022-07-30 10:12:18

i dunno many things

yeah malloc 5*sizeof(char)

alexmb7 2022-07-30 10:13:06

yea hum big time

smol_mazunki 2022-07-30 10:13:14

alexmb7 2022-07-30 10:13:21

if we can reach some average level of comm

alexmb7 2022-07-30 10:13:34

smol_mazunki 2022-07-30 10:13:06

yeah malloc 5*sizeof(char)

i see

alexmb7 2022-07-30 10:13:51

i also need s intact

alexmb7 2022-07-30 10:14:04

so like user data can have s

alexmb7 2022-07-30 10:14:26

cant use default string functions i think, gotta self code or something

alexmb7 2022-07-30 10:14:41

also i need some bignum library for math inf len

smol_mazunki 2022-07-30 10:14:51

alexmb7 2022-07-30 10:13:51

i also need s intact

yeah that’s what i meant by +1

smol_mazunki 2022-07-30 10:15:07

you know about arrays

alexmb7 2022-07-30 10:15:12

a bit

smol_mazunki 2022-07-30 10:15:29

char *my_arr = { ‘h’, ‘e’, ‘l’, ‘l’, ‘o’, ” };

alexmb7 2022-07-30 10:15:34

str = 3 , str = 5

smol_mazunki 2022-07-30 10:15:35

this is an array of chars

smol_mazunki 2022-07-30 10:15:52

chars use ‘, strings use ”

alexmb7 2022-07-30 10:15:57

mate

alexmb7 2022-07-30 10:16:18

smol_mazunki 2022-07-30 10:15:29

char *my_arr = { ‘h’, ‘e’, ‘l’, ‘l’, ‘o’, ” };

can i have this assert at runtime with user runtime data
