In C programming, characters are stored and processed using the char data type. Here's a step-by-step explanation:

1. Declaration: You declare a character in C by using the keyword 'char'. For example, `char letter;` This allocates memory space for storing a character.

2. Initialization: You can initialize a character variable at the time of declaration or later in the program. For example, `char letter = 'A';` This stores the character 'A' in the variable 'letter'.

3. Processing: Characters in C are processed as integer values. This is because each character is associated with an ASCII value, which is an integer. For example, the ASCII value of 'A' is 65. So, when you perform operations on characters, you're actually working with their ASCII values. For example, if you increment 'A' by 1 (`letter++`), 'letter' will now hold 'B', because the ASCII value of 'B' is 66.

4. Input/Output: You can take character input using the scanf function and print a character using the printf function. For example, `scanf("%c", &letter);` will take a character input from the user and store it in 'letter'. `printf("%c", letter);` will print the character stored in 'letter'.

5. Strings: In C, strings are actually arrays of characters ending with the null character '\0'. For example, `char name[10] = "John";` Here, 'name' is a string (or an array of characters) that stores "John".

6. String Processing: You can process strings using various string functions available in the string.h library. For example, you can find the length of a string using the strlen function, compare two strings using the strcmp function, etc.

Remember, in C, characters are just small integers, and you can use them in expressions just like any other integer.
