C++ program to accept three digits and print all possible combinations from these digits

#include<iostream.h>

#include<conio.h>

void main()

{

int a[3];

clrscr();

cout<<"Enter three digits :"<<endl;

cin>>a[0]>>a[1]>>a[2];

for (int i=0;i<3;i++)

{

for(int j=0;j<3;j++)

{

for (int k=0;k<3;k++)

{

if (i!=j&&i!=k&&j!=k)

cout<<endl<<endl<<a[i]<<a[j]<<a[k];

}

}

}

getch();

}

OUTPUT:

Enter three digits :
