7. Best Basic Practices and Style Guidelines

7.1 Naming Conventions

• Variables: Use descriptive names (student_count, not sc)
• Constants: Use uppercase (MAX_SIZE, PI)
• Functions (we will learn more about this in the next module): Use verb-noun pattern (calculate_area, print_result)

7.2 Code Organization

#include <stdio.h>        // System headers
#include <stdlib.h>

#define MAX_SIZE 100      // Constants

// Function prototypes (We will learn more about this in the next module)
int add(int a, int b);
void print_result(int result);

int main() {
    // Main program logic
    return 0;
}

// Function definitions (We will learn more about this in the next module)
int add(int a, int b) {
    return a + b;
}

7.3 Error Handling

Input Validation:

int num;
printf("Enter a positive number: ");
scanf("%d", &num)

if (num != 1 || num <= 0) {
    printf("Invalid input!\n");
    return 1;  // Exit with error code
}
