Reverse Word Order in C

✅ Reverse Word Order in C

#include <stdio.h>

int main() {
    char str[200];           // To store the full input string
    char words[50][50];      // 2D array to store individual words
    int i = 0, j = 0, k = 0; // i: index in str, j: index in words, k: word count

    // Input the full line (including spaces)
    printf("Enter a string: ");
    scanf(" %[^\n]", str);  // Read input until newline

    // Split the string into words
    while (str[i] != '\0') {
        if (str[i] != ' ') {
            words[k][j++] = str[i];  // Add character to current word
        } else {
            words[k][j] = '\0';  // Terminate current word
            k++;                 // Move to next word
            j = 0;               // Reset letter index
        }
        i++;
    }
    words[k][j] = '\0';  // Terminate last word

    // Print words in reverse order
    printf("Reversed word order:\n");
    for (int l = k; l >= 0; l--) {
        printf("%s ", words[l]);
    }
    printf("\n");

    return 0;
}
  

📘 Explanation:

This C program reads a full string input (including spaces), splits it into individual words using space as a delimiter, and then prints the words in reverse order.

It uses a 2D character array to store each word separately. The user input is captured using scanf(" %[^\n]", str), which allows spaces in the input.

Finally, the program prints each word starting from the last to the first, effectively reversing the sentence word-by-word.
