C - Basics and Execution Environment

#include <stdio.h>
int count = 0;
int main() { printf("Count: %d", count); return 0; }

Bint main() { int count = 0; #include <stdio.h> printf("Count: %d", count); return 0; }

C#include <stdio.h> int main() { int count = 0; printf("Count: %d", count); return 0; } int count = 0;

Dint count = 0; int main() { printf("Count: %d", count); return 0; } #include <stdio.h>

Step-by-Step Solution

Solution:

Step 1: Understand correct order of program parts
Header files come first, then global variables, then main function.
Step 2: Check each option for correct order
#include int count = 0; int main() { printf("Count: %d", count); return 0; } follows correct order; others mix header and variables incorrectly.
Final Answer:
Header, global variable, then main function in order -> Option A
Quick Check:
Correct program structure order = #include int count = 0; int main() { printf("Count: %d", count); return 0; } [OK]

Quick Trick: Headers first, globals next, then main() function [OK]
