Attempting to construct a milage calculator - c++

Question

I am attempting to construct a mileage calculator. The design is like this,
If a person drives 100 miles or less then the amount they shall be paid 25 cent per mile.
If a person drives in excess of 100 miles, they shall be paid the initial 25 cents for their first 100 miles in addition to 15 cents for every mile over 100 mile...
So an example would be
10 miles would earn the person a dollar, while 250 miles would earn (25 for the first 100 + 22.50 for the second 150) to a grand total of 47.50..
When I hit start without debugging, the program goes to the black screen to put values in. But then I receive an error message.. I am trying to figure out what it means.
I am using microsoft visual studio 2008. C++ coding.
#include <iostream>
using namespace std;
int main()
{
int varOne ;
cout << "Enter your favorite number" << endl;
cin << varOne << endl;
if(varOne <= 100)
cout << (1/4)*(varOne)<< endl;
if (varOne>= 100)
cout << (.15 * (varOne-100)) + (.25 * 100) <, endl;
return 0;
}
Debug Error!

Answer 1

Here are some simple errors I noticed in your code
cin << varOne << endl;
It should be
cin >> varOne ;
Next error
cout << (.15 * (varOne-100)) + (.25 * 100) <, endl;
This should be
cout << (.15 * (varOne-100)) + (.25 * 100) << endl;
Here are some logical errors.
In your If statements, you are checking >= and <= , Check for equality only once. Change
if(varOne <= 100)
to
if(varOne < 100)
Also change
cout<< (1/4)*(varOne) << endl;
to
cout<< (varOne)/4 << endl;
This is because 1/4 will give 0
