1.Star pattern with simple input output 

#include<iostream>
using namespace std;
int main()
{
  cout<<"*\n"<<"**\n"<<"***\n"<<"****\n"<<"*****\n"<<endl;
  return 0;
}

Output:

2.Character input output

#include <iostream>

using namespace std;

int main()

{

    char name[50];

    cout<<"Enter name:";

    cin>>name;

    cout<<"Hello "<<name<<"!";

    return 0;

}

Output:

3.Simple input output

#include <iostream>

using namespace std;

int main()

{

    int x;

    int y;

    float z;

    x=10;

    y=15;

    z=12.6;

    cout<<x<<" "<<y<<" "<<z<<endl;

    return 0;

}

Output:

4.Ascnding & descending with simple input output

#include <iostream>

using namespace std;

int main()

{

    int valu1;

    int valu2;

    int valu3;

    cout<<"Enter num:"<<endl;

    cin>>valu1>>valu2>>valu3;

    cout<< "Asending num:"<<valu1<<" "<<valu2<<" "<<valu3<<endl;

    cout<<"Dsending num:"<<valu3<<" "<<valu2 <<" "<<valu1<<endl;

return 0;

}

Output:
