# C++ Program to Find Prime Number using Constructor

#include<iostream.h> #include<conio.h> class prime { int a,j,i; public: prime(int x) { a=x; } void calculate() { j=1; { for(i=2;i<=a/2;i++) if(a%i==0) { j=0; break; } else { j=1; } } } void show() { if(j==1) cout<< "\nThis Number is prime Number!\n"; else cout<<"\nThis Number is Not prime!\n"; } }; void main() { int a; cout<<"\nEnter any Number: "; cin>>a; prime obj(a); obj.calculate(); obj.show(); getch(); }
