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.Sample InputwordSample OutputdrowD

Sure, here is a simple C program that reverses a string and prints the first letter of the reversed string in uppercase:

#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 word[100];

    printf("Enter a word: ");
    scanf("%s", word);

    reverse_string(word);

    printf("Reversed word: %s\n", word);
    printf("First letter of reversed word in uppercase: %c\n", toupper(word[0]));

    return 0;
}

This program works as follows:

1. It reads a word from the user.
2. It reverses the word by swapping the characters at the beginning and end of the string, and then moving towards the center.
3. It prints the reversed word.
4. It converts the first letter of the reversed word to uppercase using the toupper function and prints it.
