QUIZ 3

What to Do

You implement this function in your own program in a file quiz3.cpp.

You should make a main routine that asks the user for a number and then calls your functions to calculate the square and cube roots of that number and prints them out.

What should you do if the user enters a negative number?

Publish your code on your own blog today (during class time is best) and use the tag #Quiz03 so it shows up nicely in our tag cloud.

code:

#include <iostream>
#include <math.h>
using namespace std;
double square_root(double x){
double square_root= sqrt(x);
return square_root;
}
double cube_root(double x){
double cube_root= cbrt(x);
return cube_root;
}

int main(){
double x;
std::cout << “introduce un numero” << ‘\n’;
std::cin >> x;
if (x<0) {
std::cout << “error” << ‘\n’;
}else {
std::cout <<square_root(x)<< ‘\n’;
std::cout <<cube_root(x) << ‘\n’;
}
return 0.0;
};

cout<<“For you to know, the square root of a negative number is the square root of its absolute value multiplied per i, i is the square root of -1.”<<endl;

En este quiz el profesor nos pidió que hiciéramos un programa que pudiera calcular tanto la raíz cuadrada, como la cubica del mismo numero.

Para esto utilice variables tipo double y así tener una mayor precisión sobre el resultado. El programa lo hice lo mas sencillo posible para poder entenderlo más fácilmente.

Quiz 3

Quiz 3 :

First i added the library “cmath” so i can use the functions for square and cubic root , then i declared some variables for to use as shown.

Inside the main function i ask the user for the value of x, then i send the value of x to the function Square_root , that returns the value for the result for the square root . when it finishes it goes back to the main and then sends the value of x to the function Cubic_root and returns a value for the result.

i have an if-else to decide if the x value is negative to decide if its a imaginary root.

Enjoy!

CODE HERE:

#include <iostream>
#include <cmath>

using namespace std;
double x1,x2,x, squareroot , cubicroot ;

double Square_root (double x) {

squareroot = sqrt( x );
return squareroot ;
}
double Cubic_root (double x) {

cubicroot = cbrt (x);
return cubicroot;
}
int main()
{
cout << “Escribe el valor de x” << endl;
cin >> x;

x1 = Square_root(x);
x2 = Cubic_root(x);

if (x >0 ) {

cout << “la raiz cuadrada de ” << x << “es ” << x1 << endl;
cout << “la raiz cubica de ” << x << “es ” << x2 << endl;

}
else {

cout << “La raiz es imaginaria ” << endl;
}
return 0;

}

The difficult part of this quiz was know the difference between a variable and input:

first I was really confuse because when i declare my variable of square-root I didn’t know what was the wrong part, then I realized that i dint declared it in the right place, I had put it inside the int main so the terminal didn’t know what variable I was talking about.

terminal

The easy part:

finally when I got the point of every command I copy paste. after that I was experimenting.

this side really help me with all the commands that i didn’t know

My first real quiz!! it was hard at the beggining and I was driving nuts! but I DID IT!!!

#include <iostream>
#include <math.H>
using namespace std;

double square_root(double x){
double param;
param=sqrt(x);
return param;
}
double cube_root(double x) {
double param;
param=cbrt(x);
return param;
}
int main () {
double x;
cout<<“hey, give a number!”<<endl;
cin>>x;
cout<<“the square root of “<<x<<” is: “<<square_root(x)<<endl;
cout<<“the cube root of “<<x<<” is: “<<cube_root(x);

return 0;
}
