C++ :: How To Calculate Number Of Scores Above 90
Apr 7, 2013
I have a program that allows the user to enter a specific number of test scores. Based on these test scores, the program should display the average score and calculate how many of the scores were above 90. I have most of it done but I'm having trouble figuring out how to calculate the number of scores that were above 90. What am I doing wrong?
This is my code:
#include <iostream>
#include <iomanip>
using namespace std;
// Function prototypes
double average(double*, int);
int howManyA(double*, int);
[Code]...

I have created a program that allows for a user-defined number of test scores as input. After the user enters these scores, the program calculates the average test score. Here is my code:
#include <iostream>
#include <iomanip>
using namespace std;
// Function prototypes
double getAverage(double*, int);
[Code] .....
I am having trouble with the final part of my program. How do I pass the array of test scores to a function that calculates how many people got an A (90+) on the test? The final output should look like this:
The average of those scores is:
The number of A grades is:

I have to create a program that calculates the final scores per diver, who each get five dives. I have to include the difficulty level when figuring out this score, and I need to drop the highest and lowest scores.
Now, I'm reading from a file where the values are something like:
234 :Diver number
2.3 :Difficulty
2.1 3.2 4.0 2.3 3.8 :Scores
Would I create a parallel array for the difficulty, or include it in a 2D array with the scores. Something like
score[Difficulty][individualScores]; ?
Also, would I include a findMin and findMax in a function that calculates the total, seeing as how the highest and lowest must be dropped to determine the final score?

it compiles and runs, it gives me the average and the highest score but says lowest is 0 even though 0 is never entered.
Write a program which uses an array of 5 scores and calculates the average score, the highest score and the lowest score.
#include <iostream>
using namespace std;
int getHighest(int [], int);
int getSmallest(int [], int);
double getAverage(int [], int);
int count;
int numbers;

Okay so suppose that a text file grade.txt contains an unspecified number of scores. How would I program that reads the scores from the file and displays all the scores, their total and average? Scores are stored in the format of one score per line. Im having trouble with the whole #include <fstream> file and how to lay it all out in visual studio.

So I have a template, part of a larger code, that is designed to calculate the number of multiplications it took to reach a certain number. The problem is, whenever I execute the program, mults is always printing out a strange number, perhaps its actual address.
template <class T>
T power3(T x, unsigned int n, unsigned int& mults) {
if (n == 0) return 1;
if (n == 1) return x;
if (n == 2){

i'm trying building my how Write() function:
template <typename T>
....
Write(T Argument1[,T ArgumentX])
how can i calculate the numeber of Arguments added? (in C we used an argument for tells how many we putted in a function, but not in these case)

I assume floating point numbers in C++ have a default maximum of 5 decimal places. You can use setprecision() but is this limitless?
So how would find say write a program to calculate Pi to N number of places?

I'm trying to write a code to calculate the minimum number of coins needed to cover a change. It works fine but i want to display a message telling the user to try again if they type something that's not a number or a negative number. But it's not working. When i type a negative number, the program runs normally and displays a negative value of coins instead of showing the message. And when i type something that's not a number, the program just keeps showing a lot of zeros nonstop. And when i try to compile it with 'unsigned float' instead of just 'float' i get errors.
Code:
#include <stdio.h>
int main()
{
unsigned int coins;
float change;
unsigned int n25, n10, n5, n1;
unsigned int r25, r10, r5;
}

I need to create a program that has has an array size of 20 and will generate 20 random numbers in it between 1-1000. Then I need to calculate the average of all the random numbers.
I have half of the code done ,but im lost on how to calculate the average of the random numbers.
Here what I have:
#include <iostream>
using namespace std;
int i;
int size[20];
int counter = 0;
int main() {
cout << "The Array Consists Of 20 Random Numbers: "<<endl<<endl;

I am trying to do a simple calculation. I just started C++ and learning about decisions. My program should calculate number of tickets and apply discount based on the number of tickets purchased. It will only execute one of the decisions.
#include <iostream>
using namespace std;
int main() {
double qty; // qty of tickets
double discount; // % of discount.

So I have to write a program to calculate a grade letter into a number.
Letter grades are A, B, C, D, and F, possibly followed by + or â. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or Fâ. A + increases the numeric value by 0.3, a â decreases it by 0.3. If the letter grade is illegal (such as "Z"), then your output should be "INVALID LETTER GRADE"; If the combination is illegal (such as "A+" or "F-") then your output should be "INVALID GRADE COMBINATION"
Also the code should look like this
Enter your letter grade: C+
Grade value is [2.3]
// Input
cout << "Enter your letter grade: ";
string s;
cin >> s;
[Code].....

Write a C++ program to calculate the fewest number of each denomination needed to pay a bill of amount TOTAL. For example, if the end user enters $97 for TOTAL, program will output that the bills would consist of one $50 bill, two $20 bills, one $5 bill, and two $1 bills. (Assume that the amount is in whole dollars, no cents, and only $100, $50, $20, $10, $5, and $1 denominations are available.) Aid: You may want to use the modulus operator %.

I'm trying to calculate the number of distinct values entered into an array. If i enter the followings "3,4,5,6,7,7,6,e (anything that's not a number)" . I get a total of 7 but in reality it should be a 5.
Code:
#include <stdio.h>
//---------function to find the distinct values----
int find_distinct(int list[], int size)
{
int i, j,size2, distinct = 0;
for(i = 0; i < size; i++)

I have this simple program below:
Code:
#include <stdio.h>
#include <limits.h>
unsigned int rightrot(unsigned int x, unsigned int n) {
/* calculate number of bits in type */
size_t s = sizeof(x) * CHAR_BIT;
[Code] ....
The result it prints is 2684356604 on my 32-bit computer. The result I expect is as follows:
0xFF94 is 0000000000000000 1111111110010100 in binary.
Shift it right by 5:
0000000000000000 0000011111111100
Then take that result in shift it right by 27 (s is 32 and p is 5, so the difference is 27):
1111111110000000 0000000000000000
Now we use bitwise or:
0000000000000000 0000011111111100 | 1111111110000000 0000000000000000 = 1111111110000000 0000011111111100
That in decimal is 4286580732. So how does it come up with 2684356604?

I have an assignment to write a program that will calculate the number of days between two dates (including leap years). We have to read the data from a file and in my current input file I have:
1 1 2000 1 5 2004
5 2 2005 2 5 2009
1 15 1998 1 15 2001
for testing purposes. When I run the program the console runs continuously spouting out "The days between your two dates are 1097." Which would be the correct output for the last set of dates entered, but I need to find out where I've messed up in my main.
#include <iostream>
#include <fstream>
using namespace std;
bool isLeap(int x) {
if (x % 400 == 0) {

I am currently working on an assignment.
#include <iostream>
using namespace std;
int main(int argc, char *argv[]) {
char letter;
int count = 0;
double ppl = 0;
double finalCost = ppl * (count - 1);
[Code] ....
I am trying to create a word counter program that asks for the price per letter and then asks for the sentence they are writing. The app should then calculate the number of letters and give the total cost similar to:
You have 40 letters at $3.45 per letter, and your total is $138.00.
Everything compiles fine but when I run it the inputs don't work and it outputs:
You have -1 per letter, and your total cost is $-0.

I am trying to code and compile a program that requests a uses to first inpu the number of sides they wish for a dice to have and secondly input the number of dice throws they would like to calculate the value for. The program will print an error message and default the number of sides the dice has to 5 if the number entered is below 4. Finally it will print out a percentage figure for each value that results from all the the dice rolls.
I have attached my header, driver and class files below along with accompanying error messages below them
// file name Exercise.cpp
#include <iostream>
#include "Die.h"
using namespace std;
int main() // the main program begins here
{
char restart = 'y'; // declare variables
double numRolls = 0.0;
int diceTot = 0;

Code:
#include <stdio.h>
void ListPermutations(char str[]);
void RecursivePermute(char str[], int k);

I am in comp. Sci 1 at my school and I have to write a program that deals with gamer scores and the trophy they get according to expert level. For example Tom is a beginner and gets a gold medal if >=10000 a silver >= 7500 bronze if >= 5000 and no trophy if he score <5000 ! I have do this scoring for Beginner, Immediate and Expert.
Should I set up the beginning like this:
case'b':
case 'B':
if (score >= 10000 )
trophy= gold
if (score >= 7500)
trophy = silver
if (score >= 5000)
trophy= bronze
else = none
Not really sure how to go about solving this problem

I have a problem on my program. I want to display the scores on notepad. I can display it but the problem is every time I play the game the previous score got erased and replaced by the new one.Here's my code.
cout<<" Enter your name: ";
cin>>a;
cout<<endl<<endl;
cout<<" Your name is "<<a<<" and your score is "<<right<<endl<<endl;
ofstream MyFile ("score.txt");
MyFile << a <<" "<<right;
MyFile.close ();

I'm trying to basically have a user input the amount of test they want averaged, then have the user input the test scores. Send the test scores to a function and have them ordered in ascending then send it to another function that averages it. When I wrote the function I keep getting the address back instead of the actual values.
#include <iostream>
#include <iomanip>
using namespace std;
void arrSelectSort( int* [], int);
void arrAverage(int);
