Function programming task 3. Arithmetic test
A primary school teacher wants a computer program to test the basic arithmetic skills of her students. Generate random questions (2 numbers only) consisting of addition, subtraction, multiplication and division. The system should ask the student’s name and then ask ten questions. The program should feed back if the answers are correct or not, and then generate a final score at the end.

Acommon algorithm for converting a decimal number to binary is to repeatedly divide the decimal number by 2 and save the remainder. this division is continued until the result is zero. then, each of the remainders that have been saved are used to construct the binary number. write a recursive java method that implements this algorithm. it will accept a value of int and return a string with the appropriate binary character representation of the decimal number. my code: public class lab16{public string converttobinary(int input){int a; if(input > 0){a = input % 2; return (converttobinary(input / 2) + "" +a); } return ""; } }
