Create a copy of an array | C Programming Example

[pepanek]

Love your courses! Is using memcpy for copying the array OK or are there any pitfalls?
Something like memcpy(c, array, length*sizeof(int));

Nice, But We can make our function works with other types like this 🙃 :

enum {CHAR = 1, SHORT = 2, INT = 4, LONG = 4, LONG_LONG = 8, FLOAT = 4, DOUBLE = 8, LONG_DOUBLE = 16};
void *array_copy(void *array, int length, int type){
void *array_cpy = malloc(length*type);
for(int i = 0 ; i < length*type ; i++){
((unsigned char*)array_cpy)[i] = ((unsigned char*)array)[i];
}
return array_cpy;
}

this is because in chat gbt they said void pointer type cast is that means that malloc retairn a void pointer

Brilliant, thank you. I have a follow up question, what if we do not know the length of the array we are pulling from a database?

[alialharki]

It is very good thanks my compiler said that we have to do in order to rxplaine it if you could?

How can we do this on char string array?

this man is dumb, you could simply use the spread operator

const copy = [ ...original ]
