issue with code

[denver2020]

Can anyone tell me the issue with below code? will it be segmentation fault?

        #include <stdio.h>

        int main()

        {

            char *str = "hello, world\n";

            str[5] = '.';

            printf("%s\n", str);

            return 0;

        }

Perhaps C isn't as strict as C++ here, but line 8 should be a const char*, not char*, since you're pointing to read-only memory.

You are not allowed to modify the memory of a string literal (line 10), so this is likely what is causing a segfault.

Copy it into an array, first.
char str[] = "hello, world\n";

The type of str is const char* (pointer to const char) and not char*. Hence you shouldn't try to change the data at L10. This would produce a compile error as C++.
