Explanation by: Chandani

There will be a compilation error, because we cannot assign a string like this (str2 = str1). To resolve this issue, we have to use strcpy(str2,str1).

The output will be:

main.c:8:10: error: assignment to expression with array type
    8 |     str2 = str1;
      |          ^
