Programacion C++ Basico

Practica01 :orden inverso
#include<iostream.h>
main(void)
{
int a,b,c,d;
cout<<"valor a";
cin>>a;
cout<<"valor b";
cin>>b;
cout<<"valor c";
cin>>c;cout<<"valor d";
cin>>d;
cout <<"valores inversos"<<d<<c<<b<<a<<"\n";
return 0;
}
________________________________________________

Practica 02:
#include<iostream.h>
main(void)
{
int a,b,c;
cout<<"valor a";
cin>>a;
cout<<"valor b";
cin>>b;
c=a+b; cout<<"el resultado es"<<c<<"\n";return 0;
-------------------------------------------------
}

Practica03
#include<iostream.h>
main(void)
{
int a,b,x;
cout<<"valor a";
cin>>a;
cout<<"valor b";cin>>b;
x=a+b/3;
cout<<"resultado"<<x<<"\n";
return 0;
}

Practica04
#include<iostream.h>
main(void)
{
float a,b,c,d,e,x;
cout<<"calificacion a";cin>>a;
cout<<"calificacion b";
cin>>b;
cout<<"calificacion c";
cin>>c;
cout<<"calificacion d";
cin>>d;
cout<<"calificacion e";
cin>>e;x=(a+b+c+d+e)/5;
cout<<"calificacion"<<x<<"\n";
return 0;
-------------------------------------------------
}
Practica05
#include<iostream.h>
main(void)
{
int a,x,x1;cout<< "valor a";
cin>>a;
x=(a*a);
x1=(a*a*a);
cout<<"cuadrado"<<x<<"\n";
cout<<"cubo"<<x1<<"\n";
return 0;-------------------------------------------------
}
Practica06
#include<iostream.h>
main(void)
{
int a,b,h,p;
cout<< "altura";
cin>>h;
cout<<"base";
cin>>b;
a=(b*h);
p=2*b+2*h;
cout<<"areaes"<<a<<"\n";
cout<<"perimetro es"<<p<<"\n";
return 0;
-------------------------------------------------
