How can I return a string to the operating system in my C code?

Question

I am a C beginner and this is my C code:

#include 
#include 

main()
{
    printf(\"Hello, World!\\n\");
    return \'sss\';
}

You could do this in a way similar to scanf. In other words:

void foo(char **value_to_return) {
    *value_to_return = malloc(256); // Store 256 characters
    strcpy(*value_to_return, "deposited string");
}

int main() {
    char *deposit;
    foo(&deposit);
    printf("%s", deposit);
    return 0;
}
