Develop a C++ program that teaches elementary school students multiplication. Use rand to produce two positive one-digit integers. It should then type a question such as:How much is 6 times 7?The student then types the answer. Your program checks the answer; if it is correct, the correctMessage function is called; if it is incorrect, the incorrectMessage function is called. Your program will count the number of correct and incorrect answers. After 10 answers (any/all responses count), the program will calculate the percentage of correct responses. If the percentage is lower than 75%, your program will call the needHelp function, then terminate. Otherwise, the program continues until the student enters the sentinel value (-1) to end the program.Here is the code. The parts of the code that is provided can not be changed. I just need the missing code inserted where the [Solution goes here] tag is. // using Microsoft Visual C++ 2010 Express#include using std::cin; using std::cout; using std::endl; #include using std::rand;using std::srand;#include using std::time;void multiplication(); void correctMessage(); void incorrectMessage();
