Answer 2

Answer:

Error : 'z' undeclared

Explanation:

In order to understand the error message, let us write a simple program where a variable z is not defined in the program.

C program

#include <stdio.h>

int main()

{

    printf("%f", z);

   return 0;

}

When we run the compiler of C, it will show the following error;

Error : 'z' undeclared (first use in this function) printf("%f", z);
