Question

Consider the following statements in C to write a program in their order of occurrence :
A. Printf("%d", i);

B. void main ( )

C. int i=5;

D. #include <stdio.h>

Choose the correct answer from the options given below :

• A. D, B, C, A
• B. B, D, C, A
• C. B, C, A, D
• D. D, B, A, C

Hint:

Remember the skeleton: Include $\to$ Main $\to$ Declare $\to$ Execute. You can't use a tool (printf) without its manual (stdio.h), and you can't print a variable (i) before you create it!

Answer 1

The Correct Option is A

Concept:
• A C program follows a strict structural hierarchy required by the compiler.
• Components must be declared or defined before they are used in statements.

Step 1: Preprocessor Directives (D)
The #include statement must come first so that the compiler can load definitions for standard functions like printf.

Step 2: Function Definition (B)
The entry point of every C program is the main() function. It follows the include section.

Step 3: Variable Declaration and Initialization (C)
Inside the main function, variables must be declared (and optionally initialized) before any logic uses them.

Step 4: Executable Statements (A)
The actual logic, such as printing the value of the variable, comes after variables are initialized.

Step 5: Synthesize the code
#include <stdio.h> void main() { int i = 5; printf("%d", i); Sequence: D \(\rightarrow\) B \(\rightarrow\) C \(\rightarrow\) A.
