Answer:

Here is the calcPrice.c program:

#include <stdio.h>   //to use input output functions

int main(void)  {  //start of main method

   int itemNo, month, day, year, quantity;  //declares variables to hold item number, quantity, and date

   float unitPrice; //declare variable to hold price per unit

   printf("Enter item number: ");  // prompts user to enter item number

   scanf("%d", &itemNo);  //reads item number from user and stores it in itemNo variable

   printf("Enter unit price: ");  // prompts user to enter unit price

   scanf("%f", &unitPrice);  //reads input unit price and stores it in unitPrice variable

   

    printf("Enter quantity: ");  //prompts user to enter quantity

   scanf("%d", &quantity);  //reads input quantity and stores it in quantity variable

   printf("Enter purchase date (mm/dd/yyyy): ");  //prompts user to enter purchase date

   scanf("%d/%d/%d", &month, &day, &year);  //reads input date and stores it in month, day and year variables

    float totalAmount = unitPrice * quantity;  //computes the total amount

   printf("\nItem\tUnit Price\tQTY\tPurchase Date\tTotal Amount\n");  //displays the item, unit price, qty, purchase data and total amount with tab space between each

   printf("%d\t$%5.2f\t%d\t%.2d/%.2d/%d\t$%5.2f\n", itemNo, unitPrice,quantity, month, day, year,totalAmount);   }    //displays the values of itemNo, unitPrice, quantity, month, day, year and computed totalAmount with tab space between each

Explanation:

Lets suppose user enters 583 as item number, 13.5 as unit price, 2 as quantity and 09/15/2016 as date so

itemNo = 583

unitPrice = 13.5

quantity = 2

month = 09

day = 15

year = 2016

totalAmount is computed as:

  totalAmount = unitPrice * quantity;

 totalAmount = 13.5* 2

totalAmount = 27.00

Hence the output of the entire program is:

Item    Unit Price      QTY     Purchase Date   Total Amount      

583     $  13.50           2           09/15/2016         $  27.00  

The screenshot of the program along with its output is attached.

Andrew [12]

Answer:

a. Compile code

Explanation:

In programming process, the following are important in defining what a program is to do;

i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program.  The purpose of a program should be defined in the program.

ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.

iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.

iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.

Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.

Define Class in C++. Briefly discuss.
lesya [120]

Answer:

Class are the collection of variable and member function.

Class are the blueprint of an object.

Explanation:

Following are the points regarding class in c++

1.In C++ class is an user defined datatype..

2.Classes are the collection of variable and function in c++.

3.To access the property of class we can create object of that class

4.We can use following syntax to declared any class in c++

class classname

{

accessmodifier:

//statement and function

};

main()

{

classname objectname;

}

implementation of class in c++

#include<iostream>

class test // class declaration

{

public: // access modifier

void fun3() // Method definition

{

cout<<" hello :";

}

};

void main() // main function

{

test ob;// creating object

ob.fun3(); // calling function

}

In this program we declared a class "test " in class test. We giving public access modifier .The public access modifier define that variable and function are accessible outside the class and in main method we create the object ob which call the function fun3().

Output:hello :

Using the functions from problems 1 and 2, write a MATLAB script to compare the laminar results from to the turbulent results. C
suter [353]

To start combining, select the Merge Mode option on the Comparison tab. Next, click the button next to the line you wish to merge in order to replace content from the right pane with content from the left pane.

<h3>How is boundary layer thickness calculated?</h3>
  • Where x is a position parallel to the wall, y is a coordinate normal to the wall, v is a (small) viscosity, u = (u, v) is the velocity, is the vorticity, and so on. The boundary conditions are as follows: u(x,y = +,t) = U, and u(x,y = 0,t) = 0.
  • To gauge the overall pressure, a vertically sliding Pitot tube is employed. So that the growth of the boundary layer in the flow direction can be seen, the total pressures can be recorded at various distances from the plate surface. Static pressure is gauged at a different measurement location.
  • To start combining, select the Merge Mode option on the Comparison tab. Next, click the button next to the line you wish to merge in order to replace content from the right pane with content from the left pane. Alternatively, you can pick a discrepancy and choose Replace Content from the Comparison tab.
