#include <iostream>

using namespace std;

int main(){

int n1,n2, s=0;

cout << “Dame el primer numero del rango: ” << endl;
cin >> n1;

This is my code for this assignment:

#include <iostream>
#include <stdlib.h>
#include <time.h>

using namespace std;

int main(){
int num, c, usuario;
srand(time(NULL));

for(c = 1; c <= 100; c++)
{
num = 1 + rand() % (101 – 1);
}
cout<< num << endl;

do{
cout << “Tengo un número escogido entre el 1 y el 100, trata de adivinarlo”<< endl;
cin>>usuario;

if (usuario<num){
cout << “El numero es muy bajo, intenta otra vez” << endl;
}
else
if(usuario>num){
cout << “El numero es muy alto, intenta otra vez” << endl;
}
} while(usuario!=num);

if(usuario==num){
cout<<“Correcto! El número sí es “<< num << endl;
}

return 0;
}

 

This is how i did this assignment:

#include <iostream>
using namespace std;

int a, b, r, m, d, rem;

int main(){
cout<< “Give me two integers values”<< endl;
cin>>a;
cin>>b;
r=a-b;
cout << “resta= ” << r << endl;
m=a*b;
cout << “multiplicacion= ” << m << endl;
d=a/b;
cout << “división= ” << d << endl;
rem=a%b;
cout << “residuo= ” << rem << endl;

return 0;

}

This is the basic hello world program on C++

#include <iostream>
using namespace std;

int main(){

cout<< “Hello world”<< endl;
return 0;
}
