two dimensional arrays help

Simple Encryption and decryption
Question is
The user will enter a word (a maximum of 20 characters or until the user presses Enter) and your program should encrypt or decrypt the word based on the users choice. The idea is to find the correct letter and pring the corresponding one.

The code I did is

---

insert

Code:

---

#include <stdio.h>
int main()
{
    char original[27]{'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',' '};
    char encrypted[27]{'H','F','L','R','U','O','P','C','B','A','Z','E','W','D','G','Y','I','M','K','N','X','S','J','V','Q',' ','V'};
    char word[20];
    char processed[20];
    int i,j;
    printf("Please enter the word: \n");
    for(i=0; i<20; i++){
            scanf("%c", &word[i]);
            if(word[i] == '\n')
    }
   
    for(i=0; i<20; i++)
    for(j=0; j<27; j++){
        if(word[i] == original[j]);
       
    }

I couldnt continue :(

Thank you so much for your time

Why couldn't you continue? I remember I had to write this in assembly for an antique processor when I was in university.

Its a compulsory subject from the university although it won't open for me any course later on since my major doesnt include programming n those stuff.. its hard :(
The point where im stuck at is how can i compare the word that ill enter it with the encrypted one?
I didnt know how to use the if Function
thank you

You compare strings with strcmp. I suggest you Google it and look over some examples.
