2. Write a C-program to input two initials of your name, your height in inches and weigh
   stones; convert the height to centimetres and weight to kilograms and display the follow
   results.
   PERSONAL DETAILS
   AGRIC
   IDENTIFICATION: BH
   HEIGHT (cm): 180
   WEIGHT (Kg): 75
   Tote: 1 inch 2.54 cm and 1 stone

3. Convert a temperature reading in degrees Fahrenheit to degrees Celsius, using the formul
   C = (5/9) * (F-32).
   Test the program with the following values: (degrees Fahrenheit)

#include <stdio.h>

#define INCH_TO_CM 2.54
#define STONE_TO_KG 6.364

void convert_and_display_personal_details() {
    char initial1, initial2;
    int height_in_inches;
    float weight_in_stones;

    // Input initials
    printf("Enter your initials (2 characters): ");
    scanf(" %c%c", &initial1, &initial2);

    // Input height in inches
    printf("Enter your height in inches: ");
    scanf("%d", &height_in_inches);

    // Input weight in stones
    printf("Enter your weight in stones: ");
    scanf("%f", &weight_in_stones);

    // Convert height to centimeters
    float height_in_cm = height_in_inches * INCH_TO_CM;

    // Convert weight to kilograms
    float weight_in_kg = weight_in_stones * STONE_TO_KG;

    // Display results
    printf("\nPERSONAL DETAILS\n");
    printf("IDENTIFICATION: %c%c\n", initial1, initial2);
    printf("HEIGHT (cm): %.2f\n", height_in_cm);
    printf("WEIGHT (Kg): %.2f\n", weight_in_kg);
}

void convert_fahrenheit_to_celsius() {
    float fahrenheit_values[] = {68, 150, 212, 0, -22, -200};
    int num_values = sizeof(fahrenheit_values) / sizeof(fahrenheit_values[0]);

    printf("\nFahrenheit to Celsius Conversion:\n");
    for (int i = 0; i < num_values; i++) {
        float celsius = (5.0 / 9.0) * (fahrenheit_values[i] - 32);
        printf("%.2f°F = %.2f°C\n", fahrenheit_values[i], celsius);
    }
}

int main() {
    convert_and_display_personal_details();
    convert_fahrenheit_to_celsius();
    return 0;
}

Explanation of the Code:

1. Constants: The program defines constants for the conversion factors from inches to centimeters and stones to kilograms.
2. Function convert_and_display_personal_details:
   • Prompts the user to enter their initials, height in inches, and weight in stones.
   • Converts height to centimeters and weight to kilograms.
   • Displays the personal details in a formatted manner.
3. Function convert_fahrenheit_to_celsius:
   • Contains an array of Fahrenheit values to be converted.
   • Loops through the array, converts each value to Celsius using the provided formula, and prints the results.
4. main function: Calls the two functions to execute the tasks.

How to Compile and Run:

1. Save the code in a file named personal_details.c.
2. Open a terminal and navigate to the directory where the file is saved.
3. Compile the program using:

   gcc personal_details.c -o personal_details
   

4. Run the program using:

   ./personal_details
