I am currently doing a complex number calculator ,and i wish to output my data to a txt.file . i tried fstream and it doesnt work. However the txt.file was created but no text was output.
Below is the program:
#include<iomanip> #include<cmath> #include<iostream> #include<fstream> using namespace std; #define PI 3.14159265358979323 double z,x;
[Code]..
When impedance A & B are in series,the effective Impedance is " <<setprecision(4)<< z << " + j" <<setprecision(3)<< x<<endl;
else cout << "
When impedance A & B are in series,the effective Impedance is " <<setprecision(4)<<z << " - j" <<setprecision(3)<< x*(-1)<<endl; } void Complex::showdiv(double &z,double &x) { if ( x>= 0 ) cout << "
When impedance A & B are in parallel,the effective Impedance is " <<setprecision(4)<< z << " + j" <<setprecision(3)<< x <<endl; else cout << "
When impedance A & B are in parallel,the effective Impedance is " <<setprecision(4)<<z << " - j" <<setprecision(3)<< x*(-1) <<endl; }
class Polar:public Complex //inheritant from class Complex { protected: double r,d,r2,d2; public: void PolarValue(); void ShowPolar();
I'm supposed to read a text file and display it in the output. I have it down except my formatting. I just cannot get it to just skip one line rather than multiple. I know why though because my char has a max of 11 and if I put a character lets say mango, it is going to fill in the rest with white spaces. It's supposed to display like this:
Mango Strawberry Grapes
But instead I get something like this
Mango
Melon
Grapes
I am using isspace but it's not working.

I have a more complicated program I'm wishing to have display the output, however, to save some time I'm using an example of a shorter version. count the lines in input and display the output in terminal when ./program is executed after compilation. To count and compute lines, words and within arrays.
I created class called students which suppose to store students names of in array but when I call the display function it display only the first name. but I want it to display names depending on the array size.
#include <iostream> #include <sstream> using namespace std; const int SIZE=5;
I know this is more simple than I am making it out to be. I have a solar panel hooked up to an 8-Bit ADC and linked into my Microprocessor. I am trying to take the Binary readout from the ADC and convert it to a decimal number to be displayed on the boards LCD display. I am wiring the ADC to PORTA on my Motorola Freescale Board. This is for a final project for my electronic systems class due on Monday...
I am stuck on my program right now, what i am trying to do is get the sum of the amount from a access database table and than display it on a label, however i cant seem to get this to happen. This is what I have so far:
OleDbConnection conn = new OleDbConnection(); conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Church.accdb"; conn.Open(); Form1 frm1 = new Form1(); //frm1.Show(); //string tableName = frm1.tableName; //string time = "4/5/1991"; string fullName = memberscmb.Text;
I am trying to call Display menu. If up key is pressed Displayed has to be incremented and stay in particular window if Decremented, go to previous Display function and show previous Display function. LCD & Keypad Shield Quickstart Guide | Freetronics
I'm writing a program that will display 70 random temperatures, using an array that stores each number. They are going to be divided into weeks (7 temperatThe loures per line), and before displaying each of the seven temperatures, I want to first display the week #. The loops I'm using work, however the variable 'i' always first displays 2, and then counts. The loop initializes it to 0, so I don't know why it's immediately obtaining a value of two. The code is posted below.
Code: static void DisplayTemps(int[] a) { Console.WriteLine("Su M T W Th F S"); for (int i = 0; i < a.Length / 7; i++) { Console.Write("Week {0} ", i); for (int j=(i * 7); j < a.Length; j++)
I'm trying to display data from a text file named ace_data.txt. Here's a preview of the first three lines i want to display:
2001 106 15 2002 65 12 2003 175 16
So basically, here is what my code looks like...
Code: #define FILENAME "ace_data.txt" int main (void) { FILE *inp, *outp;
[Code] ....
And nothing is displayed when i run the program. I feel like I made some mistake with the fopen() and fscanf() functions but I'm not so sure how to correct them.
I have a very simple application that I want to display counts on a textbox. The problem is that the counter freezes the entire program and it only shows the last count. So I want to count from 0 to 100 incrementally with a delay of 250ms per count and display as it counts on the text box. 0...1...2...3......100 etc
Code: private void count() { for (int i = 0; i < 101; i++) { textBox3.Text = i.ToString(); Thread.Sleep(50); } }
I've got a problem with a piece of code that it doesn't seem to work anymore.
Code: #include <stdio.h> #include <conio.h> main () {

I chose a to be 5 and it displays the following:
"Type a value for a: 5 5 in octal is: 5 5 in hexadecimal is: 5
Process returned 23 <0x17> execution time : 1.031 s".I first saw this when trying to display the address of a pointer. Am i missing something? I used to run this code on dev-c++ successfully but after a day or so of practice, it's not working anymore. I switched from dev-c++ to code blocks.
I'm pretty new to C, just looking to see how to display a image and some text to go along with it so far I can display in the image but cannot display the text at the same time.
