Write A C++ Program To Find Greatest Number Among Three Integer Numbers.

By Dinesh Thakur

In the example, the user is prompted to enter values for three numbers a, b and c. It then checks for the test condition (a>b). If this condition is true then it checks for the test condition (a>c) using the if-else block contained in it. If the condition (a>c) evaluates to true then the message a is the Greatest is displayed otherwise the message c is the Greatest is displayed.

But if the condition (a>b) evaluates to false then it checks for the test condition (b >c) using another if-else statement contained within else block. If the condition (b>c) evaluates to true then the message b is the Greatest is displayed else the message c is the Greatest is displayed. 

#include<iostream.h> 
 #include<conio.h> 
 #include<dos.h> 
 void main() 
 { 
                int a,b,c,g; 
                clrscr(); 
                cout<<endl; 
                cout<<"Enter the three numbers:"; 
                cin>>a>>b>>c; 
                if(a>b) 
                  { 
                       if(a>c) 
                        { 
                            g=a; 
                        } 
                      else 
                        { 
                            g=c; 
                        } 
                   } 
                 else 
                   { 
                       if(b>c) 
                         { 
                             g=b; 
                          } 
                       else 
                          { 
                              g=c; 
                          } 
                     } 
                          cout<<endl; 
                          cout<<"Greatest number is: "<<g; 
                          getch(); 
 }
