I need help with doing this programming assignment.

Programming Exam Description You work for a small tie company. Code a modular program that will accept an order of ties that will need to allow users to pick the tie type and the desired pattern. Your program will calculate the total of the order of ties. Do not accept any values for ties other than the possible menu options. Use the table below to calculate the individual tie costs. Tie Tie Type Pattern Cost Solid $5.99 '13:: Paisley $9.99 Striped $7.99 solid $7.99 N15}? Paisley $9.99 Striped $11.99 In addition to main, the program must contain prototypes, denitions. and call the followingfunctions: 1. getTies function Ask the user how many ties will be ordered. Validate the input ofthe ties so that the user must enter at least one tie before proceeding with the program. Function must return the validated number ofties. 2. getTieType function Use a menu to prompt the user for the tie type. This should be done using a function that accepts a numberfor the current tie number and displays the tie type menu. This function must: prompt the user for a selection and return the choice. User must be given an unlimited number of chances to enter a valid tie type choice. Function must return the validated tie type. 3. getPattern function Prompt the user forthe tie pattern using a menu. This should be done using a function that accepts the current tie number. User must be given an unlimited number of chances to enter a valid tie pattern. Function must return the validated tie pattern. 4. calculateTieCost function Include a function that calculates the cost of the tie. This function should accept the tie type and the tie pattern. Function must return the tie cost. Use global constant: for the tie costs. Calculate and display the total cost. of the order of all ties. Dollar amounts should be properly formatted. Sample Run
