#include <iostream>
using namespace std;

int main( )
{

　　int num1,num2;

　　cout<<"Enter the divendend:";

　　cin>>num1

　　cout<<"Enter the divisor:";

　　cin>>num2;

　　quotient=num1/num2;

　　remainder=num1%num2;

　　cout<<num1 <<"divided by"<<num2<<"is"<<quotient<<"\n";

　　return 0;

}

 

8.a.52.0

b. the program only transfer 20 celsius degree into fahrenheit, the programmer wanted to input the degree that needs to be transferred. Also the 9/5 gives back a whole number instead the exact result of 9/5, so need to be rectified as 5.0/9.

cout<<"input the degree Celsius.";

cin<<c;
double f;
f = (9.0/5) * c + 32.0;
