    #include<stdio.h>
    int main(void){
    char s1[] = “Hello”;
    char s2[] = “World!”;
    s1 = s2;
    printf(“%s”,s1);
    }

• A.  “World!”
• B. “HelloWorld!”
• C. “Compilation error”
• D. “Hello”

Answer 1

Option : C

You cannot assign anything to array variable without specifying indices. So, it's a compilation error.

Answer 2

Ans : C

Reason:-

∴ In C, the main function serves as the entry point for the program. According to the C standard, the main function should have a return type of int, indicating the exit status of the program. Therefore, it should be declared as int main(void) and not void main(). Using void main() is not standard and may cause a compiler error.

Answer 3

array name cannot be used in left side of assignment.
Option C. "Compilation Error"
