Problems
create a C++ program that will do the followings

- define 3 double variables x, y, z

- calculate the value of y as the following formula: y = 2*x*x+4*x+5 and print x and y;

- assign a new value to x: x=5.6

- calculate the value of z as the following formula

z = (y*y)/4 + (x*x)/5

- print x, y,x

Expert Solution

CODE:

#include <iostream>
using namespace std;
int main()
{
double x;
double y;
double z;
cout<<"Enter a floating point value: ";
cin>>x;
cout<<x<<" is stored into x\n";
//y=2*x*x+4*x+5
y = (2.0*x*x)+(4.0*x)+5.0;
cout<<"Y is calculated as per this formula <y=2*x*x+4*x+5>\n";
cout<<"And the value of Y is = "<<y<<"\n";
//z=(y*y)/4+(x*x)/5
cout<<"The value of x is changed to x=5.6\n";
x=5.6;
cout<<"Now Z is calculated as per this formula <z=(y*y)/4+(x*x)/5>\n";
z=(y*y)/4+(x*x)/5;
cout<<"And the value of z is = "<<z;;
return 0;
}

You will create a program with 3 methods. For the previous homework with three problems, you will create a method for each problem. In the main method, you will declare the three arrays and create the memory space for each of them. The first method will receive a one dimension array and then it will assign the values ( e.g., a[4] = 4*4*4*4;). The second method receives a 2 dimensional array and creates the calendar. The third method receives a...

C or C++ program Create a list of 5 things-to-do when you are bored (in the text file things.txt, one line each), where each thing is described as a string of characters of length in between 10 and 50. Design a C program to read these things in (from stdin or by input redirection) and store them in the least memory possible (i.e., only the last byte in the storage for each string can be the null character). After reading...
