Thread: Invalid Memory Access when passing string literals to an argument

I'm trying to call this search and replace function, and it says invalid memory access.
How should I modify the function, so that it would be possible to pass literal strings as arguments.

Code:

#include <stdio.h>
#include <string.h>




void function(const char * string){


    char *pointer = strstr(string, "out");
    if (pointer != NULL) {
        memcpy(pointer, "in", 2);
        memmove(pointer + 2, pointer + 3, strlen(pointer + 3) + 1);
    }
    printf("%s\n", string);


    
    
}


int main(void) {
    function("cat is out roaming");


    return 0;
}

Code:

75cc8e8a : at ???: RUNTIME ERROR: invalid memory access
../lib/bcheck.c:1699: by __bound_memcpy
replace_text.c:9: by function
replace_text.c:24: by main

Expected output:

Code:

cat is in roaming

You can't modify string literals because they're placed in read-only memory.

You either have to
- pass another parameter pointing to some memory where you want the modified string placed.
- allocate some memory inside function and return that pointer back to the caller.
