// Conditional Statements in CPP


#include<iostream>
using namespace std;
int maxdata();
int main()
{
    system("cls");
      int n;
      cout<<"Enter a number";
      cin>>n;
      if(n==1)   
      cout<<"One";
      if(n==2)
      cout<<"Two";
      if(n==3)
      cout<<"Three";
      if(n==4)
      cout<<"Four";
      if(n==5)
      cout<<"Five";
      if(n>5 || n<0)  
        cout<<"Invalid Number ";
    return 0;
    
}   

Program 2

#include<iostream>
using namespace std;
int getValue();
int main()
{
    system("cls");
     int x;
    if(x=getValue()>10)
    {
      cout<<"Hello";
    } 
     else
       cout<<"Bye";

     cout<<x;  
    return 0;
}
int getValue()
{
     int n;
      cout<<"Enter a number";
      cin>>n;
      return n;
}

Program 3

// if else

#include<iostream>
using namespace std;
int getValue();
int main()
{
    system("cls");
      int n;
      cout<<"Enter a number";
      cin>>n;
        

    return 0;
}
