I am doing a very basic program that takes the length of the sides of a triangle or rectangle, calculates the perimeter then outputs it to a file.
I am getting the error :
fatal error C1075: end of file found before the left brace '{'
but i can't figure it out.
I will attach the cpp file.
Any help would be extremely helpful
Thanks!
Post your code--do not attach files. I'm not in the habit of downloading programs that could be viruses from strangers who post on the internet.
Thats bcoz your file formatting is all wrong.
Your classes 'triangle' and 'rectangle' are not closed
In C++ all the class declarations should be closed with a };
Also your main should be global here it seems to be within storedata().
Have a look at a proper C++ sample and you would figure out your mistakes
Thanks for the input. I put a closing brace for the rectangle and triangle class.
I am getting an error with my second class it says:
error C2236: unexpected 'class' 'rectangle'. Did you forget a ';'?
But I structured it identically to the first class. Can anyone see what I did incorrectly?
THANKS!
here is the code:
Code:#include <iostream>
#include <fstream> //for file interaction
using namespace std;

{
sideA = 0;
sideB = 0;
sideC = 0;
perimeter = 0;
}
void getdata()
{
cout << "Enter the length of Side A ";
cin >> sideA;
cout << "Enter the length of Side B";
cin >> sideB;
cout << "Enter the length of Side C";
cin>> sideC;
}
void calc()
{
perimeter = sideA + sideB + sideC;
}
void Tri_type()
{
if(sideA+sideB<sideC||sideB+sideC<sideA||sideA+sideC<sideB)
cout<<sideA<<','<<sideB<<','<<sideC<<" is"<<" NOT A TRIANGLE"<<endl;
else if(sideA==sideB&&sideB==sideC)
EQUILATERAL=type;
else if(sideA==sideB||sideB==sideC||sideA==sideC)
ISOSCELES=type;
else
SCALENE=type;
}
void printdata()
{
cout << "Perimeter of the Triangle is" << perimeter;
cout << endl;
cout << "Type of Triangle is" << type;
cout << endl;
}
void storedata()
//end of while
{
char another = ' ';

fstream fileObj;
//opens files to prepare for writing out and appending
fileObj.open("triangleinfo.txt", ios::out | ios::app);

} while (another == 'y');
fileObj.close(); //closes file
system("pause");
}
}
class rectangle
{
public:
int sideA;
int sideB;
int perimeter;
public:
//constructor

{
sideA = 0;
sideB = 0;
perimeter = 0;
}
void getdata()
{

void calc()
{

}
}
int main()
{
int option = 0; //resets to 0
while((option <=0) || (option >=2))
{
cout << "Enter 1 for TRIANGLE" << endl;

cout << "Enter now -> ";
cin >> option;
if ((option <=0) || (option >=2))
{
cout << "BAD INPUT-- try again!!!" <<endl;
system("pause");
system("cls");
}//end of if
}
switch(option)
{
case 1:
{
triangle mytriangle;
mytriangle.getdata();
mytriangle.calc();
mytriangle.Tri_type();
mytriangle.storedata();
mytriangle.printdata();
break;
}
case 2:
{
rectangle myrectangle;
myrectangle.getdata();
myrectangle.calc();
myrectangle.storedata();
myrectangle.printdata();
break;
}
return 0;
}
}
Still can see lotz of issues in your code.
1) Move all your methods from SetData() to storedata() inside the class
2) Close the class with };
3) Keep your main as global i.e outside all your classes.
I suggest you write some simple C++ classes and understand the syntax before proceeding.
Placing of main is ok. You have some flaws regarding class declarations and usage though. That or you're trying to make everything inline. If so, the closing brace should be after all methods have been defined. I.e. you should only have the declaration part below but with the addition of full implementations of the methods.
Declaration of a classImplementation of the class:Code:class Name {
int member1;
int member2;
public:
Name();
void method1();
void method2();
};
Using the class:Code:Name::Name()
{
// Whatever
}
Name::Method1()
{
// Whatever
}
Name::Method2()
{
// Whatever
}
Code:int main()
{
Name stackInstance;
Name* heapInstance = new Name;
stackInstance.Method1();
heapInstance->Method2();
delete heapInstance;
return 0;
}
The compiler told you exactly what the problem was:
Look at this portion of your code:Quote:

Of course, there are other issues - as others have pointed out - but the solution to this one was handed to you.
I have rewritten the program from scratch, figuring my other one was too far gone.
I have it working fine, but I have one problem perhaps you could help with.
After I selected triangle or rectangle and input the variables, it outputs the data then asks me to unput the variables again before it ends.
I want to get rid of that 2nd round of inputting
Any suggestions:
Code:#include <iostream>
#include <fstream>
using namespace std;

int sideB;
int sideC;
char type[15];
int perimeter;
public:

{
sideA = 0;
sideB = 0;
sideC = 0;
strcpy_s(type, " ");
perimeter = 0;
}
void getdata()
{
shape::getdata(); //calls parent class function
cout << "Enter the length of side A: ";
cin >> sideA;
cout << "Enter the length of side B: ";
cin >> sideB;
cout << "Enter the length of side C: ";
cin >> sideC;
}
void calc()
{
perimeter = sideA + sideB + sideC;
if(sideA==sideB&&sideB==sideC)
strcpy_s(type, "Equilateral");
else if(sideA==sideB||sideB==sideC||sideA==sideC)
strcpy_s(type, "Isosceles");
else
strcpy_s(type, "Scalene");
}

}
}; //end of tape

switch(option)
{
case 1:
{triangle mytriangle;
mytriangle.getdata();
mytriangle.calc();
mytriangle.printdata();
break;
}
case 2:
{
rectangle myrectangle;
myrectangle.getdata();
myrectangle.calc();
myrectangle.printdata();
break;
}
return 0;
}
}
thats because inside triangle printdata() you call getdata() again after outputting the values
I see, but I want the option to run the program again, without calling getdata() again, the option for "another" doesn't work.
Any suggestions?
