Question

Using C++ please create a program for a first grader to practice subtractions. The program randomly generates two single-digit integers number1 and number2. Ask the user to input the difference of the two numbers with always the greater number as the first operand. If the user inputs wrong answer, print a message, “Your answer is wrong. The correct answer is ” with the correct answer. Otherwise print “Your answer is correct.”

Hint:

1. Check if number1 < number2, otherwise swap them

2.Ask the user what is “number1 – number2”?

3.Print the message according to the user input

Answer 1

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main(){
   int number1, number2;
   
   srand(time(0)); 

   number1 = rand()%10;
   number2 = rand()%10;
   
   if(number1 < number2){
      int t = number1;
      number1 = number2;
      number2 = t;
   }
   
   int res;
   cout<<"What is "<<number1<<" - "<<number2<<" ? ";
   cin>>res;
   
   if(number1-number2 == res){
      cout<<"Your answer is correct."<<endl;
   }
   else{
      cout<<"Your answer is wrong."<<endl;
   }
   
    return 0;
}
