C :: Enter Test Marks Of Several Students And Calculates Average Marks Of Each Student
Mar 10, 2013Write a program that a prof can use to enter the test marks of several students and which calculates the average mark of each student. Ask the user how many students he has, then ask him to enter each student's marks. When 999 is entered, calculate the average mark for that student (not counting the 999) and print the average. Then go on to the next students until the marks for all students have been entered, calculated and the average printed.
Code:
#include<stdio.h>
main() {
float student,mark,total=0;
float a,b,c;
int num = 999;

C++ :: Adding Students And Calculating Their Marks
Feb 20, 2013I need to write a program on that language. I start with the explanation: The program has 3 tasks:
First: User can add the First Names, Second Names, Third Names and the Marks of a students.
Second: The program can calculate the Avarege Marks of the students.
Third: To show the students that have marks more than 5.50.
C++ :: Write A Program To Store Marks Obtained By 50 Students?
Feb 28, 2014Q.1 Write a program to store marks obtained by 50 students. Initialise the array having passed to a function initilise() having passed the array as parameter. Write another function which should take this array as parameter and return the highest score from the array. you have to write the proper function call, prototype and definition for each function.
And this is the program which i wrote and got errors: -
#include<iostream.h>
#include<conio.h>
#define s 50
void init(int m[s]);
void display(int m[s]);
void find_max(int max, int m[s]);

C :: Correct Answer Does Not End Game
Feb 21, 2013Okay so I thought I had this assignment completed properly last week. Last night I found a bug while playing the game.why won't the game end when the player guesses the correct number? The game allows you to finish using the max number of guesses even though you already guessed the correct number.
Code:
#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>
#include <time.h>
#include <stdlib.h>

#define MAXGAMES 20

C :: What Is Correct Way To Print A Float
Feb 17, 2013I have a program that printf a float that is returned by a function like this:
Code:
printf("%3.1f
", myfloat());
...
float myfloat(void) {
code....
}
In w32 my program has been running ok, but when run in a w64, it crash at the printf. If I change the definition of the function to return double it runs ok. in printf format string - Wikipedia, the free encyclopedia , in the "type" section I see there is no definition to print a float, but %f is for double in fixed point.So the question is what is the correct way to printf a float? must I cast? or is it better to return double? if so, does it have a performance penalty?
C++ :: Operator Overloading In A Correct Way?
Apr 1, 2013Well... I observed, as a non-professional programmer that "overloading operators" has some strict rules and some conventions... so any operator can differ from another. In order to have a clearest idea, I'd like to ask you to specify, for every operator, the correct (or best) way to overload it.
There are cases where you define &operator and cases where you define operator (without "&"). There are cases where operator are defined as "friend" inside class, and other cases where operator is declared externally.
example: ostream &operator<<
(why it uses & ??)
So can we have a summary for all kind of operators?

C++ :: Giving Score To Correct Player
Jul 22, 2013I have programmed a game where you guess a number (1-6) and if the number is equal to the random number then give the player score + 10. But if I have selected for example 4 players then if the game will give player 1 a score it gives player 2 a score instead? What can be causing this error?

C :: How To Call Function With Correct Arguments
Sep 13, 2013I'm not a programmer, at least, not a good one. I'm a researcher and I need to implement this function and test it and use it for my research. I tested some clustering methods in JAVA and Matlab and also I want to test it on C. I don't know too much about programming, especially about C, I know nothing. I tried to implement some basic methods but I failed.
It's all about K-Means Algorithm. I'm working on a disease and I'm trying to find ways to early diagnosis. Anyway, these are details. The thing is, I found a 'free to use' function but I don't know how can I use it. I tried to learn something from Net, I downloaded a compiler, I paste the code and I get many errors... And I heard that I have to do some "calling function" stuff but I don't know how to..
The code is in the link below: URL....It's not imperative that using this function, it can be another one but it had to written in C.
C :: File Could Not Be Opened While Filename Seems Correct
Feb 10, 2013I'm new to C and encountered a weird problem. Here's the code:

",name);
printf(name);

I compile this with no problem, but gives "File could not be opened". the strcmp tells me name and "snazzyjazz.txt" are not equal. but when I print them I get the same output.

C/C++ :: Output Is Not Correct - Squaring Input?
Feb 6, 2015Ok so This is what the output of the program should be.
enter the count of input integers: 1
The count of the integers must be two or more. Please enter a valid number : 3
Enter integer #1 : 2
Enter integer #2 : -1
Enter integer #3:5
The positive numbers entered and their squares are:
2 4
5 25

C++ :: Enter A Value And It Will Return Corresponding Correct Answers From Tables
Dec 17, 2013Currently I have to manually look up values on several different tables in different locations. I have 8 or 10 tables with 100 to 500 parts.
I would like to write a program so if I enter a value it will return the corresponding correct answers from the tables.
If I entered 2.5 for a value it would return the following three items from the tables since they all meet the requirement.
Table 2
Part min max
235 2.4 2.9
Table 6
Part min max
589 2.3 2.5
Table 7
Part min max
12 2.3 2.7
What would the best method be for setting up and accessing tables like this? Is C++ good at representing something like this or should I be looking at a different language?
C :: Array Function Not Returning Correct Values
Apr 1, 2013I have been trying to make a function that compares all the values of the array and if they are all equal will return a value to print true.

C :: Getting Correct Float Value Without Having To Write In Width / Precision
Jul 16, 2014I have this
Code:
#include <stdio.h>
int main() {
float number1, number2;
printf("Enter two numbers separated by a comma ");
scanf("%f,%f", &number1, &number2);
[Code] ....
When it prints the values, it prints them as I want. the problem is, what happens when someone puts in values with different width and precision? Here I had to write in the width and precision to display the values that are specified in the book. but what happens when someone puts in something that doesn't have those width/precision?
I end up with a lot of zeros after the number. initially I got 24.000000 (zeros are not accurate amount) I needed to show just 24. (with the decimal)
So I included %2.0f which gave me 24 (without the decimal point) what if some one put in 24.556. I got 25 as a result.
Does the width mean how many numbers in total including the decimal point and that is a minimum?
C++ :: Program To Output A Check With Correct Spacing
Oct 14, 2013So I have to write a program that outputs a check with correct spacing and everything.
Create a project titled Lab7_Check. Write a program that asks the user the check information and prints the check. The dialog should be as follows:
date: 2/23/2010
name: William Schmidt
amount, dollars: 23
cents: 30
payee: Office Max
your check:
William Schmidt 10/13/2013
pay to: Office Max $23.30
twenty three and 30/100 dollars
You may assume that a person always has the first name and last name (no middle names or initials). The payee name is also always two words. The dollar and cent amount are integers and the amount is always less than 100 dollars. Note that the dollar amount could be zero, in which case, when you spell the dollar amount, it should print "zero". The date is always a single (non-white space separated string). Your date, dollar amount in numbers and the word "dollars" have to vertically align.
This is the code I have so far.
#include <iostream>
#include <string>
using namespace std;
int main(){
string date;
string firstname;
string lastname;

Jan 21, 2013We know that function pointer for virtual function are stored in a vtable.When we have multiple function pointer entry in vtable and we call one of the virtual function then how the corresponding or correct function pointer is retrived from Vtable? Who do this stuff? In assembly code i can not see any code or logic to detrmine the correct function pointer.
