Hi everyone, I was solving a problem of finding the biggest angle in the triangle . I first examined if there is a triangle with entered numbers and then calculated angles, found maximum and express it in degrees,minutes and seconds. But it says in line 22 that there is a mistake.(It's written that function is overloaded).In lines 23,24,25 it shows also mistakes.

Code:

#include<iostream>
#include<cmath>
using namespace std;
int main(){
double a,b,c;
cout<<"Enter a,b,c :";
cin>>a>>b>>c;
if(a>0 && b>0 && c>0 && ((a+b<c) || (c+b<a) || (a+c<b))){
double gama=acos((a*a+b*b-c*c)/2*a*b);
double alfa=acos((b*b+c*c-a*a)/2*b*c);
double beta=acos((a*a+c*c-b*b)/2*a*c);
double pi=4*atan(double(1));
gama*=(180/pi);
alfa*=(180/pi);
beta*=(180/pi);
if((alfa>beta)&&(alfa>gama))
double max=alfa;
else if((beta>alfa)&&(beta>gama))
double max=beta;
else if((gama>beta)&&(gama>alfa))
double max=gama;
**max*=3600;
int degrees=int(max/3600);
int minutes=int(((max)-3600*(degrees))/60);
int seconds=int(max-3600*seconds-60*minutes);**
cout<<"The biggest angle : "<<degrees<<" degrees"<<", "<<minutes<<"minutes"<<"i"<<seconds<<"seconds"<<endl;
}
else cout<<"It doesn't exist";
return 0;
}
