I tried this but it's also not working

Well, you need to copy the string

If you try writing the chars to the string you are reading from, that can cause danger

For example, "abcd'

You look at last letter, it is d

So you put it in index 0 to get "dbcd"

Well when you get to the last index, you will need the 1st letter

But "a" is nowhere to be found

Here is what I would suggest

int len = strlen(str)
for (int i = 0; i < len/2; i++) {
    char tmp = str[i];
    str[i] = str[len-1-i];
    str[len-1-i] = tmp;
}

Try smth like this

I'm not supposed to use pre-defined functions
That's why i add 1 to j everytime an element in the array doesn't evaluate to 0

for (i = 0; *(s + i); i++){
j += 1;
}

Idk what ur doing in the screenshot bc its so small but you can probably use recursion to reverse a string

also you can just make your own strlen function pretty easily and toomany's code will work for what u want
