Which of the following is false statement about C program?

• All valid C programs must contain the main() function.

• The code execution begins from the start of the main() function.

• To use printf() in our program, we need to include stdio.h header file using #inclue <stdio.h> statement.

• The printf() is a library function to read formatted input to the screen

int main ()

{

int x = 24, y = 39, z = 45;

z = x + y;

y = z - y;

x = z - y;

printf ("n%d %d %d", x, y, z);

}

• 39 24 63

• 24 39 45

• 39 24 45
