Math instruction: Math instructions refer to all output instructions that uses the data of two words or registers and perform the desired function. Math instructions are program based on the type of processor used. The data manipulation instructions are almost similar to math instructions. The math instruction allows the Programmable Logic Controller (PLC) to take more of conventional computer qualities. Math instructions are normally used to perform arithmetic functions on the values stored in memory words or registers. Negate function: Negate function is used to change the sign of source value from positive to negative or vice versa. It is denoted as NEG. Terms used: The following terms are used in the instruction. Source Source refers to the address of the piece of data that is used in the instruction. Destination Destination refers to the address where the results of the instruction are stored.

3.) File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.

Returns an US standard formatted phone number, in the format of (xxx) xxx-xxxx the AreaCode, Prefix and number being each part in order. Testing Hint: We be exact on the format of the number when testing this method. Make sure you think about how to convert 33 to 033 or numbers like that when setting your string format. Reminder the %02d - requires the length to be 2, with 0 padding at the front if a single digit number is passed in.

Here are some notes to help you work the problem: • strcpy(char *dst, char *src) copies the string at address src (including the terminating '\0' character) to address dst. It does not check the size of the destination buffer. You will need to know the hex values of the following characters:
