1. Create a few fields: A readonly array of possible operators, the problem's operator, and each of the two (2) terms

Answer 1

using System;
class Sample {
static void Main() {
Random r = new Random();
while(true){
int randVal= r.Next(4);
int n1= r.Next(100);
int n2= r.Next(100);
int value;
if(randVal==0){
Console.WriteLine(n1+" + "+n2+" = ");
value=Convert.ToInt32(Console.ReadLine());
if(value==n1+n2){
Console.WriteLine("Correct");
}else{
Console.WriteLine("Wrong");
}

}
else if(randVal==1){
Console.WriteLine(n1+" - "+n2+" = ");
value=Convert.ToInt32(Console.ReadLine());
if(value==n1-n2){
Console.WriteLine("Correct");
}else{
Console.WriteLine("Wrong");
}

}
else if(randVal==2){
Console.WriteLine(n1+" * "+n2+" = ");
value=Convert.ToInt32(Console.ReadLine());
if(value==n1*n2){
Console.WriteLine("Correct");
}else{
Console.WriteLine("Wrong");
}

}
else if(randVal==3){
Console.WriteLine(n1+" / "+n2+" = ");
value=Convert.ToInt32(Console.ReadLine());
if(value==n1/n2){
Console.WriteLine("Correct");
}else{
Console.WriteLine("Wrong");
}

}
}
}
