a)Write a c++ program to check maximum and minimum of two integer numbers.(Use inline function and Conditional Operator)
For Run program in Turbo C++:
--------------------------------------------------------------------------------------------
#include<iostream.h>
#include<conio.h>
class check{
public:
inline int maximum(int a, int b){
return ((a<b)?a:b);
}
inline int minimum(int a, int b){
return ((a>b)?a:b);
}};
void main(){
check c;
int a,b;
cout<<"\nEnter 1st Number:";
cin>>a;
cout<<"\nEnter 2nd Number:";
cin>>b;
cout<<"\nMaximum Number is"<<c.minimum(a,b);
cout<<"\nminimum Number is"<<c.maximum(a,b);
