C++ Programming Code to Find Largest of Three Numbers

Following C++ program ask to the user to enter the three numbers to check which one is the largest or the biggest one of the three numbers, then display the result on the screen :

/* C++ Program - Find Largest of Three Numbers */
		
#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();
	int a, b, c, big;
	cout<<"Enter three numbers : ";
	cin>>a>>b>>c;
	//let a is the biggest
	big=a;
	if(big<b)

		if(b>c)
		{
			big=b;
		}
		else
		{
			big=c;
		}
	}
	else if(big<c)
	{
		if(c>b)
		{
			big=c;
		}
		else
		{
			big=b;
		}
	}
	else
	{
		big=a;
	}
	cout<<"Biggest number is "<<big;
	getch();
}
