Nested if-else in c++

Prog 7: Write a program to find max. value from three values by using nested if-else.

  #include<iostream.h>

#include<conio.h>

void main()

{

int a,b,c;

clrscr();

cout<<"enter the value of a:";

cin>>a;

cout<<"enter the value of b:";

cin>>b;

cout<<"enter the value of c:";

cin>>c;

if(a>b)

{

        if(a>c)

         cout<<"a is max.";

         else

         cout<<"c is max.";
 

}

else

{

         if(b>c)

         cout<<"b is max.";
          else

        cout<<"c is max.";

  }

getch();

}

Output:

enter the value of a:11 enter the value of b:12 enter the value of c:13 c is max.
