code in C

Hiding the contents of communications that can be viewed by entities other than the intended recipient could be done by encoding the message using a cypher and possibly a key known only the transmitting and receiving entities. Write a program that does the following. 1- Prompts the user to enter a word that is three letters long (all lower case). 2- Reads each character into a character type variable. 3- Ask the user for a cipher key, an integer between 3 and 6. 4- Store the Cipher key in an integer variable. 5- Subtract cipher key value from the ASCII value of each character. 6- Output the character values adjusted by the cipher key on one line in the same order as the input with no spaces in between. 7- Output the integer ASCII values adjusted by the cipher key on another line in the same order as the input with no spaces in between. Note: prompt the user for and read the word before the cipher key. Sample input/output: Please enter a word to be ciphered that is three letters long in lower case letters: abc Please enter the cipher key, one digit between 3 and 6: 6 The cipherword is: [\] The ciphertext is: 919293
