Answer:
Algorithm:
1.Create three variables a,b,c.
2.Read the value of a,b,c from user.
3.Find maximum of a & b and assign it to m.
4.Then find maximum of c & m and assign to maxx.
5.Print maxx.
Implementation In C++:
#include <bits/stdc++.h>
using namespace std;
int main()
{
// variables
int a,b,c;
cout<<"Enter three different numbers:";
// read value from user
cin>>a>>b>>c;
// maximum of a & b
int m= ( a < b ) ? b : a;
// maximum of m and c
int maxx= ( m < c ) ? c : m;
// print maximum of all three
cout<<"maximum of three number is:"<<maxx;
return 0;
}
Output:
Enter three different numbers:12 4 15
maximum of three number is:15
