IN C PLEASE.

The below program is used to encrypt and decrypt a given phrase. Complete the missing parts and submit your main.c as well as your output.txt showing how your program runs.

// Takes a secret key and a phrase from command line // The secret key is a single lower case character // The phrase can be any length // The phrase is encrypted using XOR with key // The decrypt function tries out all keys // and prints the decrypted version to the console // A person can inspect the printout and find out what the // original key is #include  #include  // encrypts given sentence using key using XOR // key is a single lowerchase character // Hint: strlen can be used to get the length of a C-string void encrypt(char* sentence, char key) { // your CODE goes here printf("Encrypted: %s ", sentence); } // try all possible lower case characters as keys // print each decrypted string // Hint: store decrypted string in a temp variable // do not modify encryped string void decrypt(char* encrypted) { // your CODE goes here // define key and temp apropriately // printf("For key %c, we get: %s ", key, temp); } int main(void) { // your CODE goes here - define variable secret // secret is a single lowercase character // you need to use fgets to read a whole line // and then use the first character as "secret" printf("Enter secret key: "); // your CODE goes here - define variable phrase printf("Enter phrase to encode: "); // your CODE goes here // uncomment below lines when variables are defined // printf("Secret is: %c ", secret); // printf("Phrase is: %s ", phrase); // encrypt(phrase, secret); // decrypt(phrase); return 0; }
