C++ :: Compute Mean And Standard Deviation From A Set Of 10 Random Scores
Nov 18, 2014I have to write a program in which it is to compute the mean and standard deviation from a set of 10 random scores between 1 and 20. The C++ program should generate a set of scores randomly and then, compute the mean and standard deviation from such a set of scores.

C :: Read Amount Of Order From Standard Input / Compute And Print Total Price After Discount
Apr 13, 2014A Bookseller makes special discount for multiple orders of a book as follows:
AMOUNT and DISCOUNT as follows.
5-9 5% 10-14 10% 15-19 15% 20+ 20%
Write a C main function to read the amount of order from the standard input and compute and print the total price of the given order after the discount. Assume that unit price of a book is 10.00$
My problem is that.When i start with this
Code:
#include<stdio.h>
#include <stdlib.h>
int main(void)
{
int number;
float TotalPrice;
printf("enter a number:");
[Code] ....
I get 0 if i enter a number between 0 and 4(0 and 4 included). I don't know where I am doing a mistake. I also want to know if i can handle this buy just if statements. or how can i do it by while and for loops ?
C++ :: Compute The Value Of A Polynomial
Mar 27, 2014This program is supposed to find the value of a polynomial
with x being the number of terms
a[x] being the coefficients
b[x] being the exponents in each term
j being the variable
for example if
x=4
a[x]=1,2,1,5
b[x]=3,2,1,0
j=2
then the polynomial is (j*j*j)+2(j*j)+j+5
the value will be 23
however the value computed is wrong in the code below

C++ :: How To Compute Perimeter Of A Triangle
Jun 26, 2013I intended to compute perimeter of a triangle. The problem is the initial value for the triangle.

I expect to get 0 for triangle1, but I get some strange value...
Here is the result

View 1 Replies View RelatedC :: Compute Total Price Of Books By A Given Author
May 7, 2013Given a structure book defined as follows and an array lib of books
Code:
struct Book{
char title[100];
char author[100];
int price;
struct Book *nextedition;
};
struct Book lib[1000]; I'm going to write a function to compute total price of books by a given author including all books which are future editions of his book, even if the author of that future edition is NOT the specified author. title author price nextedition Book1 Author1 25 &lib[2] Book2 Author2 20 NULL Book3 Author3 30 &lib[3] Book4 Author1 35 NULL
For the example above, given the author "Author1", the function should return 90 (=25+30+35), and given the author "Author 3", the function should return 65 (=30+35).
So here's my attempt:
Code:
int totalPrice(char author[100]){
int total=0;
for (i=0; i<numbooks; i++)
if(strcmp(author, lib[i].author==0))
[Code] ....
What I'm trying to do is finding the first book in the lib of the specified author using for loop and then let the while loop do the rest. However, it seems the price is over-counted after each iteration of the for loop but I don't know how to fix it.

C++ :: How To Compute Financial Ratio With Using Header File
Aug 19, 2013How to compute financial ratio in C++ with using header file?
Calculate in c++ program with 3 different file. - 2 file (cpp file) - 1 file (header file)
Information:
formula:-
*1.*Current ratio = (current asset / current liabilities)
*2.*Gross margin = (Revenue – Cost of goods sold) / Revenue
*3.*Operating margin= (Operating Income / Revenue)
*4.*Profit margin = (Net Profit / Revenue)
*5.*ROE= (Net Income/Shareholder's Equity)
I want put 5 formula to run the program. How to put 5 formula in the program but run one formula.
EXAMPLE: In the coding, write all financial ratio. When we compile, just asking 1 formula value only. We need to fixed, which formula to run. Just adjust the coding only.

C/C++ :: Compute Sum And Average Of All Positive Integers Using Loop
Oct 8, 2014I got an assignment which asked me to create a program that asks user to input 10 numbers (positive and negative) integer. The program would be using loop to compute sum and average of all positive integers, the sum and average of negative numbers and the sum and average of all the number entered. But, the new problem is after I've entered all the number, the answer that the program gave me wasn't the answer that the program supposed to give. I don't know how to describe it, I would attach a picture and the code below:

C++ :: Program To Compute And Print A Billing Statement For Each Patient
Oct 17, 2013Community Hospital needs a program to compute and print a billing statement for each patient. Charges for each day are as follows:
a. room charges: private (P) room = $125.00; semi-private (S) room = $95.00; or ward (W) = $75.00
b. telephone charge = $1.75
c. television charge = $3.50
Write a program to get data from the keyboard, compute the patient’s bill, and print an appropriate statement. Typical input (nut yours do not have to be identical to this) is the following:
How many days was the room occupied? 5
What type of room? P
Telephone used during the stay? N
Television used during the stay? Y
Keep in mind that the user needs to know that the input can be any integer number of days for the length of stay, either (P, S, or W) for the room type, and either (Y or N) for both telephone and television options.
A statement (which yours MUST be identical to) for the data given follows:
Community Hospital Patient Billing Statement
Number of days in hospital: 5
Type of room: Private
Room charge:$ 625.00
Telephone charge:$ 0.00
Television charge:$ 17.50
TOTAL DUE = $642.50
C++ :: Program That Compute Final Average Grades Of Class
Jan 28, 2013An instructor needs you to write a program that will compute the final average grades in her class. There are 5 students in the class. Each student must take 2 exams and 4 quizzes as part of their final grade. The weight of each toward the final grade is as follows:
Exam 1 – 30%
Exam 2 – 30% Quiz 1 – 10%
Quiz 2 – 10%
Quiz 3 – 10%
Quiz 4 – 10%
You must use arrays to store each students 3 digit ID number, exam scores and quiz scores. A multi-dimensional array is mandatory. Request from the user the information needed then output all of the information as well as the final average grade for each student.
