the assignment is a simple game for children. Each child is given 10 random arithmetic questions,involving addition and subtraction, where operands and ansers are all in the range between 0 and 20. The child should be given acorrect answer is wrong. After 10 questions are answered, the score is displayed
The task involves designing and implementing and usig a class called Qand A - see Qand A .cs . Its constructor generates a question and the answer. The generated question and answer can be stored a fields.Methods can be supplied to retrieve the question and the answer. The test program TenQuestion .cs.It should run with your Qand A class - A typical outcome may be There are four fields in Qand A class , of which two operands and one operator (either + or -) are generated randomly. A trickry part may be the random generatio algorithm, becaure operands and the answer must be all in the range between 0 and 20
