Write a program in ‘C’ language, which accepts a text string from a user and prints its reverse order.

Here's a simple C program to accept a text string from a user and print its reverse order:

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

int main() {
    char text[1000]; // Assuming maximum input length is 1000 characters

    // Prompt user to enter a text string
    printf("Enter a text string: ");
    fgets(text, sizeof(text), stdin); // Read input from user

    // Remove newline character from the end of the string
    text[strcspn(text, "\n")] = '\0';

    // Print the original text string
    printf("Original text: %s\n", text);

    // Print the text string in reverse order
    printf("Reversed text: ");
    for (int i = strlen(text) - 1; i >= 0; i--) {
        printf("%c", text[i]);
    }
    printf("\n");

    return 0;
}

Explanation:

1. We declare a character array text to store the input text string provided by the user.
2. We use fgets() to read the input string from the user, ensuring that the input does not exceed the size of the text array.
3. We remove the newline character (\n) from the end of the input string using strcspn().
4. We print the original text string.
5. We iterate over the characters of the text string in reverse order using a loop, starting from the last character (strlen(text) - 1) and ending at the first character (0).
6. Inside the loop, we print each character of the text string in reverse order.
7. Finally, we print a newline character to complete the output.
