Write a program to decode phone numbers with letters in them. Create a void function decodetext(char after[], char before[]). This function should be case-insensitive. Do NOT cout in this function. The after array represents the phone number with only numbers. The before array represents the phone number with some text. Declare a char array to hold a maximum of 50 characters to receive the user input. Ask the user to enter a string. Use cin. getline(input, 50) function call to get the string from the user. Make sure to ignore (don’t decode) dashes in the string. Show the decoded phone number You may need to write other functions to make your code easier. It’s up to you.
