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?
Code: #include <stdio.h> int main() { float number1, number2; printf("Enter two numbers separated by a comma "); scanf("%f,%f", &number1, &number2);

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?
I was going through the exercises in one C programming ebook.There is this question which asks me to print a float variable in fixed decimal notation, field size of 6, right-justified, no digits after decimal point.I got printf("%6f", x );
x = float variable.
But the above code prints numbers after the decimal point, so I changed it to %d. But %d doesn't work with float variables..
I must write a function that has a one dimensional double array and the number of values in the array as its arguments. Normalize the values. I must also print the maximum, minimum, average and numbers of values above the average in the array.
The equation that computes the normalized value from a value x is:
My code does not print the correct normalized value, average and values above average.
Code: #include <stdio.h> int findMax( double array1[], int num_elements) // This function computes the maximum value of the array { int i, max=-32000; for (i=0; i<num_elements; i++)
I am making a program where the user enters numbers into an array and then a number,x. The array is sorted, then x is inserted into the appropriate place. I wrote my selection sort
Code:
void Sort(int ary[], int size) { int temp; int smallest; int current; int move; }
[code]....
put it wont print the numbers sorted when I use my print function, just the unsorted numbers.
Okay 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.
Well... 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?
I'm trying to make a number sorting program with other features, but the numbers are all wrong.
#include <iostream> #include <iomanip> #include <fstream> using namespace std; void readData(int list[], int size); int main() { int size = 50; int scores[50] = {0};
I 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?
Code: #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int cube; int number[4];
I'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.
I'm new to C and encountered a weird problem. Here's the code:
int main(){ char name[]=""; readname(name) ; printf("The filename is: %s ",name); printf(name);
[Code] ....
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.
The program does compile the average and the mean correctly. I can't understand why the standard_deviation member function isn't applying the sqrt properly:
#include <iostream> #include <iomanip> #include <cmath> using namespace std; const int N = 10; class Standard_Deviation {
Ok 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:
I am a beginner at C++, the output is pretty self explanatory. I'm trying to make a number sorting program with other features, but the numbers are all wrong.
Code: #include <iostream> #include <iomanip> #include <fstream> using namespace std;
Currently 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?
I 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. The problem I am having is that regardless of what values I enter the function is always returning true. Any way to tell the program o check all the values in one command instead I put them each,
I am trying to send a DIME Attachment as a HTTP POST using the libcurl. I using this to communicate with a SOAP API. All my other function work properly but I find the correct way to send a file as a DIME attachment.
Each time I run it I get in correct result. I even tried running with code from from my book and it failed aswell. The code from the tutorial worked some how. BTW I use DevC++ as my compiler.
