Find greater number in c++

How to write a program to find greater number using conditional operator in c++ ?

 

Code:

//prompt the user to enter three numbers and find the greatest of them
#include <iostream>
using namespace std;

int maximum(int, int, int);

int main()
{
    int a,b,c;

    cout<<"Enter three numbers ";

    cin>>a>>b>>c;

    cout<<"The largest number is "<<maximum( a, b, c);

    return 0;
}
int maximum( int x, int y, int z)
{
   int max = x;

   if(y > max)
   max = y;

   if( z > max)
    max = z;

   return max;
}

 

i need your help from glass on c++

 

Code:

#include<iostream.h>

class max{
  public:
          void get(int [],int);
          int sh(int [],int);
};

void max::get(int *a,int b)
{
   for(int i=0;i<b;i++)  cin>> a[i];
}
//------------
void max::sh(int *a,int b)
{
   int mx=a[0];
   for(int i=1;i<b;i++)
    if(a[i]>mx)  
        mx=a[i];

return mx;
}
//------------
void main()
{
  max j;
  int x[3];
  j.get(x,3);
  int m=j.sh(x,3);
  cout<<" \n MAX = "<<m;
}

 

Code:

#include <iostream>
using namespace std;
int main()
{
   int a=12,b=57;
   int greaterNum=0;
   greaterNum=(a>b)?a:b;
   cout<<'a='<<a<<endl
         <<'b='<<b<<endl
         <<"greaterNum='<<greaterNum<<endl;
   return 0;
}
