C++ :: Aligning Output Using Setw
Mar 21, 2013
I'm trying to align my output but I can't get it to look perfect. This is how it looks like in my program:
Hitch 98% FRESH
Happy Gilmore 99% FRESH
Transformers 2 100% FRESH
SpongeBob 10% ROTTEN
And this is how I would like it to look:
Hitch 98% FRESH
Happy Gilmore 99% FRESH
Transformers 2 100% FRESH
SpongeBob 10% ROTTEN
Here is my code:
void PrintAll(ostream& out, const string titles[], const int ratings[], int count) {
WriteLine(out, '=', 50);
out << "PRINT ALL" << endl;
WriteLine(out, '-', 50);

I am a bit unsure about what this piece of code aligning a struct to a page is trying to achieve.
Code:
#define PAGESIZE 1 << 12
typedef struct __attribute__((aligned(PAGESIZE))) x86_pagetable {
x86_pageentry_t entry[PAGETABLE_NENTRIES];
} x86_pagetable; It is an piece of code from an educational operating system WeenyOS.
What is the essence of aligning a struct to a page?

My question is simply how do I center the lines on top of one another using setw (without the use of an additional header file or an additional function)?
I've attempted
Code:
setfill(' ')
to no avail as well.
I can manually set the numbers of setw of course, but I was hoping for alternative smarter fix (without having to pain staking manually set & test each setw).
Note for reason I cannot use an additional header file or function: I've always wanted to know if this could even be done without the use of the <strings> header file (and without the use of an accompanying function). That, and I wanted to reduce the amount of lines of code if possible. If there's not an easier way that's fine (just wanted to know if setw or setfill could get the centering job done alone).
I didn't think it could be done (I believe with the header files I have and place & with no additional functional support one would have to simply manually set each setw).
Code:
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
int main() {
char Enter;

So I have an array portfolio [i][j] where i and j are determined by inputs by the user. I can get the code to fill the array with the correct values; however, I can not figure out how to output the array to csv.
Is there a simple way to output to a csv? Is it easier to create the csv file and just write to it?
This is all I have so far:
for( i=0; i<sizevol; i++){
for(j=0; j<sizespot; j++){
myfile.open ('')
}
}

In my code the cout phrase is supposed to give me an angle in degrees. no matter which 2 points i enter in, it always outputs the angle between them to be 57. This is because the acos value of 0 in degrees is 57. The program compiles without error.
Here is the code:
/*
Synopsis: This program reads in the coordinates of two 2D vectors and outputs the angle between the vectors in degrees.
*/
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
// function prototypes
// ENTER FUNCTION PROTOTYPE FOR normalize() HERE.
void normalize(double & x, double & y);

So I have a .txt file with, Name >> Username >> password >> adminstatus. It is filled with various names. for e.g.
Bob bobby bob123 1
tim timmy tim123 1
rit ritty rit123 0
john johnny john123 0
mary maryy mary123 mary 1
1 will represent admin in the program and 0 will represent a normal user. I want to make part of the program do something like this. > If adminstatus = 1, discount rate =3%. The thing is I will be using UDF to do so and I am unsure of how I am going to read for each user. What I mean by this is. If tim logins, how do I read ONLY tims line's admin status.
Currently I have a Login UDF. for that UDF I return something I named Loginstatus. If the login status = 1 . It will run the current problem that I'm trying to solve which is displaying the user adminstatus's discount rate. So how am I suppose to display the line of the user that logged in.
Here is the simplified explanation of my program. The user will login ( the program will see if everything matches up[username/password] then return loginstatus =1 if the user login successfully) Once the user logs in the program will bring up a menu which will have 2 options.
1. it will let the user check it's current discount rate.
2. quit.

I have this code down except I'm very confused how to make the output come out in 3 columns.
#include<iostream>
#include<fstream>
using namespace std;
int main() {
int i, j, n, flag = 0, prime_number = 0, temp;
cout << "Enter first prime numbers that will be used or -1 to end:" << endl;
[Code] ......
My output right now is:
Enter first prime numbers that will be used or -1 to end: 20
Twin Prime Number : (3,5)
Twin Prime Number : (5,7)
Twin Prime Number : (11,13)
Twin Prime Number : (17,19)
But what I want is:
1. {3;5} 2.{5,7} 3.{11,13}
4. {17,19}

I am currently trying to understand why this example for using an array as an argument in a function has a different result than what the lecture notes say it should be.
So supposedly sum should return with the value 28, but I get 27 no matter what. I also am not very good at reading and understanding what exactly the order of operations for this function are.
Code:
#include <iostream>
using namespace std;
int sum(const int array[], const int length) {
long sum = 0;
for (int i = 0; i < length; sum += array[++i]);
return sum;

I'm not too sure why I'm missing a line from the output. I've been going over my code like crazy and something seems to cause a line which would be size = 0: [nothing here] missing in my output. Here's my code:
Code: class binSTree: public binTree<T>{
public:
void insert(const T& x); //insert node with value x
bool search(const T& x); //searches leaf with value x
[Code].....
Other files are included but they are 100% correct as I used them in my past couple of assignments. The public version of remove is suppose to call the search function and determine the result of the search for a leaf with value x. Calls private remove and returns true. Otherwise it returns false if the search isn't successful.

I've run across this issue before, but for the like of me, I can't figure out what keeps causing it. The problem compiles and runs as expected; however in the salaried object (Employee #1 in main.cpp) the console displays the number of vacation days as -858993460 instead of the value entered.
The parent Employee class is abstract with calculatePay() and displayEmployee() being pure virtualls and with a Benefits, Salaried, and Hourly class derived from it.
The Salaried displayEmployee() and the portion of the Main.cpp that contains the salaried object follows. What causing this?
Salaried displayEmployee()
Code:
void Salaried::displayEmployee()
{
cout << endl;
cout << "Employee Information" << endl;
cout << "----------------------------------" << endl;
cout << "Employee Name: " << setw(7) << FirstName << " " << LastName << endl;
cout << "Gender: " << setw(12) << Gender << endl;

I have a c program that I partially have working. The problem is basically writing a program that allows the user to input the amount of calories they plan to eat a meal and disperse the calories from top to bottom. My program produces the output in the example if I enter 1050 but the issue I noticed if the number of calories is just enough to cover the burgers I get negatives in the other variables.
For example, if I enter a total amount of calories of 1050, I can eat: Output: 2 burgers @ 770 calories (1050 - 770 = 280 calories remain) 1 bag of pretzles @ 170 calories (280 - 170 = 110 calories remain) 1 pear @ 80 calories (110 - 80 = 30 calories remain) 6 tsp. ketchup @ 30 calories If I input 1050 I get the above output but if I input a different integer such as 2000 this is my output 5 burgers @ 1925 calories 0 bag of pretzles @ 0 calories -1 apple @ -80 calories -35 tsp. ketchup @ -175 calories I can't give the full code since this assignment holds a lot of points and was up all night getting it work.
So I'll provide pseudocode
define all 4 variables burger 385, pretzel 170, pear 80, ketchup 5 print out text How many calories can you eat prompt user input
Divide user input into burger How many burgers can bet eaten subtract calories eaten from original user input
Divide calories left into pretzel How many bags can bet eaten subtract burger calories from pretzel calories
Divide calories left after preztel into pear How many pretzels can be eatn subtract pretzels calories from pear calories
Divide calories left over into ketchup how much ketchup can i use show on screen (int total)of burgers @ (int calorie total) calories show on screen (int total)bags of pretzels @ (int calorie total) calories show on screen (int total)pears @ (int calorie total) calories show on screen (int total)teaspoons of ketchup @ (int calorie total) calories
The problem I see is that subtracting the calories from the pear from the left over calories of the pretzel calories leads to a negative. If leftover calories minus 80(pear int) its less then 0 . The calculations from the pear onward to ketchup become incorrect resulting in negative output.

I tried running the code below and i got an unexpected output
Code:
#include<stdio.h>
void main() {
char a='A';
while(a)
[Code] ....
The code is supossed to give an infinite loop but instead it terminates with a=0...I tried running it with some casting like this
Code:
#include<stdio.h>
void main(){
char a='A';
while((int)a)
[Code] ....
But the output was the same as before.why the code has this unexpected behaviour???

I would like to, when running cat, send in some data like "testing" to its stdin, and then catch the output of stdout, and put it into a character array variable.Currently the parent stalls till the child is done.I imagine the parent has to some how detect that the child executed 'cat', and then send in input to stdin?Then somehow detect that 'cat' is done executing, and read the output from stdout? I have looked around and found "dup2", but I don't understand how to send in and get data to the child from the parent, especially since the "file descriptors" is not pointing to any files in the first place..

I have the following code:
Code:
void Plot(int nx, int ny, double x[350], double y[350], double C_new[350][350], int iplot){
int i, j;
char fname[50];
FILE *fp;
[Code]....
I am then taking the generated file and importing it into a plotting program (Techplot360). It would speed up the importing process if I created a binary file instead of a like above. I know that I need to use fwrite but I am unsure how to handle lines like
Code:
fprintf(fp, "TITLE= ABCDEFG_%d
", iplot); and
Code: fprintf(fp, "%f %f %f
", x[i], y[j], T_new[i][j]);
