Hi everybody

Thanks again for your helps in my last thread.

Now, I have some more problems. :(

50 Errors for this program. Certainly, a basic problem within the structure of class "Block".

This assignment is all about "Class and objects". We can use functions, but no arrays.

```
#include <iostream>
#include <iomanip>
#include <fstream>
#include <cmath>
using namespace std;
ofstream outfile ("lab8.out");
ifstream infile ("lab8.in.text");
class Block
{
public:
double weight, friction, force;
};
int main ()
{
infile>>friction>>weight>>angle1>>angle2>>angle3>>angle4>>angle5>>angle6>>angle7>>angle8>>angle9;
Block angle1, angle2, angle3, angle4, angle5, angle6, angle7, angle8, angle9;
force.angle1==(weight-(weight*friction))/cos(angle1);
force.angle2==(weight-(weight*friction))/cos(angle2);
force.angle3==(weight-(weight*friction))/cos(angle3);
force.angle4==(weight-(weight*friction))/cos(angle4);
force.angle5==(weight-(weight*friction))/cos(angle5);
force.angle6==(weight-(weight*friction))/cos(angle6);
force.angle7==(weight-(weight*friction))/cos(angle7);
force.angle8==(weight-(weight*friction))/cos(angle8);
force.angle9==(weight-(weight*friction))/cos(angle9);

infile.close();
outfile.close();
return 0;
}
