I am having some compiling problems.

[jsmi2016]

I have this program:

#include<iostream>

#include<math.h>

using namespace std;

float a,b,c;

int istriangle()

{

if(a<(b+c)&&b<(c+a)&&c<(a+b))

return 1;

else return 0;

} void area_peri()

{

float peri,area,hperi;

peri=(a+b+c);

hperi=peri/2.0;

area= hperi*(hperi-a)*(hperi-b)*(hperi-c)*1.0;

area=sqrt(area);

cout<<"[ "<<a<<","<<b<<","<<c<<" ] has an area of "<<area<<" and perimeter of "<<peri<<endl;

return; }




void classify()

{

int r=0,s=0,i=0,e=0;

if(a*a==b*b+c*c||b*b==c*c+a*a||c*c==a*a+b*b)

r=1;

if(a==b&&b==c){

e=1;i=1;

}

else if(a==b||b==c||c==a)

{i=1;}

else s=1;

cout<<"The Classification of triangle [ "<<a<<","<<b<<","<<c<<" ] is \n"; cout<<"Right : ";

if(r==1)cout<<"Yes" << endl;else cout<<"No" <<endl;

cout<<"Isosceles :";if(i==1)cout<<"Yes" endl;

else cout<<"No" <<endl;

cout<<"Equilateral :";

if(e==1)cout<<"Yes" <<endl;

else cout<<"No" <<endl; cout<<"Scalene :";if(s==1)cout<<"Yes" <<endl;

else cout<<"No" <<endl; }




int main()

{

int flag=0;

char check;

while(1)

{ cout<<"TRIANGLE PROGRAM MENU\n";

cout<<"Compute Area and Perimeter...............A" <<endl;

cout<<"Classify.................................B" <<endl;

cout<<"Quit.....................................Q" <<endl;

cout<<"Select an Option : ";

cin>>check;

switch(check)

{ case 'A': cout<<"Enter a Triple :";

cin>>a>>b>>c; area_peri();

if(istriangle()){classify();}

else

cout<<"[ "<<a<<","<<b<<","<<c<<" ] doesnot satisfy triangle inequality" <<endl;

break;

case 'B':

cout<<"Enter a Triple :"; cin>>a>>b>>c;

if(istriangle()){classify();

} else cout<<"[ "<<a<<","<<b<<","<<c<<" ] doesnot satisfy triangle inequality" <<endl;

break;

case 'Q':

cout<<"GoodBye!\n"; flag=1;

}

if(flag==1)

break;

}

return 0;

}

I am having these issues with the compiling:

prog.cpp: In function ‘void classify()’:
prog.cpp:66:41: error: expected ‘;’ before ‘endl’

Can someone please put some fresh eyes on this program to see what the issue is?


Thank you!!

We can help, but first help us by putting the code in the code tag. Simply use <>. Thank you :)

Ok! Is a small error. In your void classify() function, at if(i==1) cout<<"Yes"<< endl;. You missed out the "<<".
