Ascii (american standard code for information interchange)
in this program you will use skills from prog2:
 printf, scanf, and simple math
 type casting (char to integer)
new skills for prog3
 conditions (decisions in program flow, example: if/ else if/ else)
 type casting (integer to char)
you will need to use functions from: #include //printf, scanf
instructions:
declare all variables.
 print “hello, welcome to the number letter converter” onto the screen.
 ask the user if they would like to create a letter from a number (enter 1)
or a number from a letter (enter 2)
 get the choice from the user (1 or 2)
 you may assume the user will enter an integer for the choice
 if the user enters a 1 ask and get another number from the user
 create a letter from that number
//example: char letter = (char)inputnumber;
 add 10 to the number that was entered
 change the new number to a letter
 print all 4 onto the screen (2 numbers and 2 letters)
 if the user enters a 2 ask and get a letter (character) from the user
 create a number from that letter
//example: int number = (int)inputletter;
 add 15 to the number that was just created
 change the new number to a letter
 print all 4 onto the screen (2 numbers and 2 letters)
 if the user enters any number other than 1 or 2 print the message “ enter a 1 or 2” onto the
