### Understanding and Implementing a Simple C Program

In this section, we will break down a sample C program. This example illustrates how to use loops and character arithmetic to produce a sequence of characters.

#### Code Transcription:

```c
#include <stdio.h>
#include <stdlib.h>

int main()
{
    char myChar = 0x61;    // Initialize character with hexadecimal value 0x61 ('a')
    int i = 0;             // Initialize integer i to 0
    while(i < 26)          // Loop while i is less than 26
    {
        printf("%c, ", myChar+i);   // Print character starting from 'a' and incrementing
        i++;                        // Increment i by 1
    }
    printf("\b\b.\n");     // Backspace twice to remove the last comma and space, then print a newline
    return 0;              // Return 0 to signal successful completion
}
```

#### Explanation:

1. **Includes**:
   ```c
   #include <stdio.h>
   #include <stdlib.h>
   ```
   These lines include the standard input-output (stdio.h) and standard library (stdlib.h) headers. The `stdio.h` library is needed for input-output operations such as `printf`, and `stdlib.h` includes various utility functions.

2. **Main Function**:
   ```c
   int main()
   {
   ```
   The `main` function is the entry point of any C program. 

3. **Variable Initialization**:
   ```c
   char myChar = 0x61;
   int i = 0;
   ```
   - `char myChar = 0x61;`: Initializes the character variable `myChar` to the hexadecimal value `0x61`, which corresponds to the ASCII value for 'a'.
   - `int i = 0;`: Initializes an integer `i` to 0.

4. **While Loop**:
   ```c
   while(i < 26)
   {
   ```
   This loop runs while `i` is less than 26. Since there are 26 letters in the English alphabet, this loop will iterate 26 times.

5. **Loop Body**:
   ```c
   printf("%c, ", myChar + i);
   i++;
   ```
   - `printf("%c, ", myChar + i);`:

**Changing C Code to Print Both Lowercase and Uppercase Alphabets**

To achieve printing both lowercase and uppercase alphabets in alphabetical order using the C programming language, you can use two loops: one for the lowercase letters and one for the uppercase letters. Below is the sample code for this output.

### C Code Example:

```c
#include <stdio.h>

int main() {
    char ch;
    
    // Printing lowercase letters
    for(ch = 'a'; ch <= 'z'; ch++) {
        printf("%c, ", ch);
    }
    printf("\n");
    
    // Printing uppercase letters
    for(ch = 'A'; ch <= 'Z'; ch++) {
        printf("%c, ", ch);
    }
    printf("\n");

    return 0;
}
```

### Explanation of the Code:
- **Include the Standard Input Output Library**:
  ```c
  #include <stdio.h>
  ```
  This line includes the standard I/O library which allows you to use the `printf` function.

- **Define the Main Function**:
  ```c
  int main() {
  ```
  This is the main entry point of the program.

- **Declaration of Character Variable**:
  ```c
  char ch;
  ```
  This defines a character variable `ch` which will be used to store each letter during iterations.

- **Loop for Lowercase Letters**:
  ```c
  for(ch = 'a'; ch <= 'z'; ch++) {
      printf("%c, ", ch);
  }
  printf("\n");
  ```
  This loop runs from 'a' to 'z', printing each character followed by a comma and space. The `printf("\n");` ensures a newline after the lowercase letters.

- **Loop for Uppercase Letters**:
  ```c
  for(ch = 'A'; ch <= 'Z'; ch++) {
      printf("%c, ", ch);
  }
  printf("\n");
  ```
  This loop runs from 'A' to 'Z', printing each character followed by a comma and space. The `printf("\n");` ensures a newline after the uppercase letters.

- **Return Statement**:
  ```c
  return 0;
  ```
  This returns `0` to the operating system, indicating that the program ended successfully.

When you execute this C program, it will print the lowercase alphabet characters followed by the uppercase alphabet characters as
