Manish is fascinated by the representation of characters in C. Write a program that declares a character variable with the value 'S' and print the following pattern with the declared variable using necessary white space characters.

Sure, here is a simple C program that prints the pattern using the character 'S':

#include <stdio.h>

int main() {
    char c = 'S';

    printf("  %c\n", c);
    printf(" %c%c%c\n", c, c, c);
    printf("%c   %c\n", c, c);
    printf(" %c%c%c\n", c, c, c);
    printf("  %c\n", c);

    return 0;
}

This program first declares a character variable c with the value 'S'. Then it uses the printf function to print the pattern. The %c inside the printf function is a placeholder for a character. When printf sees this placeholder, it replaces it with the value of the variable c. The \n inside the printf function is a special character that represents a new line. It tells printf to move the cursor to the beginning of the next line.
