Can't realloc character string in C

Question

I'm having some issues with realloc, for example, this code

    char *s = (char*)malloc(sizeof(char)*17);
    s = "bruhbruhlmaolmao";
    s = (char*)realloc(s, sizeof(char)*18);
    if(s == NULL) printf("Memory allocation failed");
    else printf("%s\n",s);

I'm trying to reallocate the memory chunk that s is pointing at to a larger memory location in the heap.

I've compiled it and the compiler returns no warning. When I run the executable, It prints out nothing. I hope you can explain to me why and how to fix it

Answer 1

Well, apparently I made a dumb decision by assigning s to a string: s = "bruhbruhlmaolmao";, what I should really do is use something in string.h library like strcpy
