Write a program in C to print a string in reverse using a character pointer.Also print the uppercase of the first letter of the reversed word.

Sure, here is a simple C program that reverses a string using a character pointer and also prints the uppercase of the first letter of the reversed word.

#include <stdio.h>
#include <string.h>
#include <ctype.h>

void reverse_string(char* str) {
    int length, c;
    char *begin, *end, temp;

    length = strlen(str);
    begin  = str;
    end    = str;

    for (c = 0; c < length - 1; c++)
        end++;

    for (c = 0; c < length/2; c++) {        
        temp   = *end;
        *end   = *begin;
        *begin = temp;

        begin++;
        end--;
    }
}

int main() {
    char str[100];

    printf("Enter a string to reverse: ");
    gets(str);

    reverse_string(str);

    printf("Reverse of the string: %s\n", str);
    printf("Uppercase of the first letter of the reversed word: %c\n", toupper(str[0]));

    return 0;
}

This program works by swapping the characters at the beginning and end of the string, and then moving the pointers towards the center of the string. The toupper function is used to convert the first character of the reversed string to uppercase.
