* Problem description: design a program that contains errors, verify the "Double int" syntax rules, and learn the "hit error" method.

* Program output: Remainder

* Problem Analysis: \ maximum value, \ cpp1.cpp (6): Error c2296: '%': illegal, left operand has type 'double'
D: \ calculate the maximum value, \ cpp1.cpp (6): Error c2297: '%': illegal, right operand has type 'double'
Error executing cl.exe.

* Algorithm Design: # include <iostream>
Using namespace std;
Int main ()
{
Int a = 7, B = 4, c;
C = a % B;
Cout <c <endl;
Return 0;
}
