Please do this in C++ and test the following :
Implement the Perceptron learning algorithm. Test your program, for the following two problems:Solution
weights for storing the weights
Threshold to store the threshold
sum to store the weighted sum
output to store the 0 or 1 after comparing the sum with the threshold
values to store the values
given_value is the value that will entered by the user to test
i, j, k are loop controller
new_start is an indicator whether to start from the beginning or not while weights have been found ok for one of the 16 values
option has been used to take input from the user for program flow control

#include<conio.h>
