Write an interactive text based menu interface (using a loop) that will allow the user to
Enter a task or assignment Display all of the tasks that are in the file Find a task by Course Quit For each task, you need to keep track of:
Course Name that it is for (e.g., CS162) Description of the assignment (e.g., Finish Lab 2) Due date (e.g., 9/26/2009)
Allow the program to keep looping until user wants to quit. When the program starts, it should load the tasks from external file ("tasks.txt") into memory. When user enters the three items of a task, the program needs to read them in, save them in memory and eventually write them to the external data file ("tasks.txt"). The file format could look like: (The ';' is used as a delimiter or field seperator.)
Some Implementation Requirements:
Write at least four functions WITH arguments for this assignment. Use struct named Task to model task Use array of structs to model the collection of tasks. Hint: In this assignment, the description and course name may have multiple words in it. Therefore, you now SHOULD read using the 3 argument version of get. Watch out. When using the 3 argument version of get you need to make sure to remove the delimiter or newline. Therefore, anytime you read (even a confirmation message), make sure to eat the newline! Make sure to have a delimiter written between each item in the file – like a newline. This will be important when you read the information back from the file.
This is my code so far:
#include <iostream> int main() { char cname[25],desc[20];
In my program I open two files and write data into each, and close them. this is done in a while loop.
int main() { while() { myFile = fopen("file1.txt","w"); myFile2 = fopen("file2.txt","w"); // write data into files using fprintf() in a for loop fclose(myFile); fclose(myFile2); } }
However, after some iterations the fopen() for myFile2 fails.
Debug assertion failed! Program.... File ......srcfprintf.c Line 55
Expression (str != NULL)
I have not been ableto locate the bug in the code that is causing the failure.
I have to write a loop assigning a variable x to all positions of a string variable and I'm stuck. I don't have extensive experience with arrays and I'm also a bit confused about C-String. The problem is below.
"Given the following declaration and initialization of the string variable, write a loop to assign 'X' to all positions of this string variable, keeping the length the same.
char our_string[15] = "Hi there!";
(Please note this is a 'C-string', not C++ standard string.)"
We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.
I have tried to submit this topic before but i didn't submit my whole code and it was removed. So here it is. All I am trying to do is load form2 from form1 then back to form1 from form2 for a certain number of times the get out of the loop. I am new to C-Sharp and it seems as though I cant seem to figure out a way to do this.
Here is form1 and form2 code. I have commented out a few things I have tried.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data;
I already made a nested for loop into a while loop (below this) and now I'm trying to make the outer for loop into a do while loop, but it's not working.
#include <iostream> using namespace std; int main () { int len; int j; int i;
[Code]....
And I can't make this code do the same thing. It stops after one loop, instead of continuing to the end. Why won't the loops continue?
#include <iostream> using namespace std; int main(){ int len; cout << "Enter a number: ";
I know I need <math.h> and I know how to write tan(10) or whatever I need. However I need angles, like 100 / tan10 = 567.13. The 10 is degrees.
I am doing a fun project now that I feel more confident. However my textbook only shows me how to use the math library and only shows a few trig functions.
I am applying Trigonometric Functions to see if a car is speeding.
For instance Code: int counter; counter =0; FILE *pfile; pfile= fopen("g:myprog.txt" "w"); while (counter >100) { fprintf (case counter{something})}; how do I do this?
I am trying to display my name using outfile vs. cout and I get errors I don't know how to fix. Here is the code:
//This program will calculate the monthly payment, the total amount paid back over the entire life of the loan, // and the total interest paid over the life of the loan. #include <iostream> #include <fstream> #include <iomanip> using namespace std; int main() { ofstream outfile;
[code]....
And here are my errors:
1>z:csci207program1practice.cpp(13): error C2297: '<<' : illegal, right operand has type 'const char [16]' 1>z:csci207program1practice.cpp(13): warning C4552: '<<' : operator has no effect; expected operator with side-effect
I was following a c# book to write a WPF with a textbox. When the textbox is selected(got focus) with keyboard or mouse, it will select all text in it. I followed the book and wrote this:
private void TextBox1_GotFocus(object sender, RoutedEventArgs e) { TextBox1.SelectAll(); } private void TextBox1_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e) { var control = sender as TextBox;
[Code] ....
The book said having "e.Handled = true" is to stop the event in order to prevent the cursor being positioned on somewhere of the text instead of selecting all text. From my understanding, "e.Handled = true" is for stopping routed events. Is this means that something will run if "e.Handled = true" is not there? If yes, then what is it?
so i have this dll with a DBTProc, whenever a window gets created i want to write something in a log file. Now everytime I run it it adds three times the text in this log file, but then it does nothing anymore. I do hear a beep everytime a window get created so it doesn't actually open my file to write in
I just started by defining a stack class (stackDouble). I need to write a program that accepts an infix calculator expression, with the following operators (**, exponentiation, /, division, and, -, subtraction. The operator precedence is exponent, division, and subtraction.I need to use a stack of doubles and a stack of strings, of which I can write two classes, or write a single stack template. The user will input the expression just via cin, and there will be a # before every number, a ! before each operator, and a . at the end of the expression. '#', '!', or '.' can be input into a char variable, numbers into a double variable and operators into a string variable.
For example, the following would output 6:
# 3 ! / # 2 ! / # .5 ! ** # 2 .
As stated above, I already made up a stackDouble class. What would I need to do to create the other class (I don't think I want to do it with a template)?
Code: #include <iostream> #include <string> using namespace std; class stackDouble{
I have a batch of .pdf files (~1000) with names 001.pdf 002.pdf ...etc. Still pretty new to C, but would it be possible to write a program that would open a PDF, prompt a new name from user, and when entered, close the .pdf and open the next one in the list?
My program needs to receive data continuously from one process and the received data is read continuously by another process.But when I am trying to create a pipe using mknod on fat32 file system in linux , it throws an error saying "mknod: operation not permitted".
