Question

This is in C++ I don't understand how to get it to place multiple "Fence Segments" (without using umpteen hundred switchs! and i feel like i'm supposed to do it in a different method since we haven't learned about switch's yet...)

Design a Program that will help fanner build an enclosed fence. This will be rectangular with the character | used for the North and South fence posts and mdash used for the boards, the East and West fence posts will use the - for the fence post and: for the boards between Will ask for North/South side fence posts and the number of East/West side fence posts number NO VALUES Less than 2 will be accepted as for these values (re-ask until a valid answer is given for each) Maximum number accepted is 10 for each if a value > 10 is entered do not re-ask just use the value of 10 A looping statement must be used for this program to be signed by the instructor. Continue to Build new fence pastures until the answer is an 'N' Inputs North_South posts 4 East_West posts 3 Response N The Sample Screen output should appear as follows adapted to inputs given 2016 Old Bruin Farm Fence Builder What is the Number of North/South Fence posts? Value must be at least 2 please What is the Number of North/South Fence posts? 4 What is the Number of East/West Fence posts? 3 Pasture Built!! Would you like to build another (Y/N)? N
