I need a stopping case when user press enter array get closed and add '' at the end but how to do that?
I just spent 3 hours writing and debugging 37 lines of code. Is this normal or am I "below average" in coding abilities. I come from a C background and decided to write C++ code that I finally got right as shown below for the specific example:
Code: #include <iostream>
#include <fstream>
#include <string>
#define SPACE_SEARCH 10
using namespace std;

I think it was more the learning along the way that consumed atleast 75% of my time for this specific case. But then again, I read that programming always entails learning along the way and so its somehow no excuse for the long time taken in this specific case.
So as a matter of interest, what pace do all of you operate on, on average? i.e. LOC/day, Debugs per day or any other indicator of productivity?
Is there a way to put a mp3 file into a c program without having the windows media player pop up in the background each time you compile the program? I just wanted to input a few seconds of an audio file..

Is there any opensource tool which can check the coding style use in a program.

1.Have a procedure called FallingDistance which has one input parameter, seconds, and one output parameter, distance.
2. Compute the distance in feet an object falls using this formula: d = ½ gt2
(where g = 32.2)
3. The main program should call FallingDistance within a loop which passes the values 1 through 12 as arguments.
4. Print a table with seconds and falling distance in feet.
Sample Output (This program has no input)
Seconds Distance
================
1 16.1000
2 64.4000
3 144.9000
4 257.6000
5 402.5000
6 579.6000
7 788.9000
8 1030.4000
9 1304.1000
10 1610
11 1948.1000
12 2318.4000
In C++, the procedure is called a function. Instead of using an output parameter, your C++ function FallingDistance should return a result of type double. This is what I created:
#include <iostream>
#include <cmath>
#include <string>
using namespace std;
const double g =32.2;
double fallingDistance(double);
[Code] ....
which gave me this error:

I am trying to create an on-line product store. I'm having trouble with setting up the code to correctly acknowledge quantity desired per product item in the shopping cart at check-out. I want to be able to capture multiple impressions/hits/clicks per item and increase the # in the quantity box each time someone clicks on the same item. For example, if product A is clicked 3 times, then the quantity in the shopping cart should show "3". If it's clicked 5 times, it should show "5" and so on ... However, right now, it's showing the product multiple times in the shopping cart with a quantity of "1" for each time the item was clicked. How can I correct this?

I wrote a program that reads user input string using fgets() function. After this, program will ask if the user wants to save the string to file or does the user want to change the string or quit without saving. If user wants to change the string this must be made possible by asking for the string again. After this, menu will be printed again printing the choices available.
I had to flush stdin before getting changing input! However, problem is "Why do I have to hit return key 2 times, when I choose 2 and input string again." (I use code block 13.12 with windows 8.1 laptop) */

I'm trying to end my program when the user presses the enter/return key.
I'm trying to do this with a break statement.
I have two different situations, one when it is a string, and the other one when it is a char.
for (int i = 0; i < 80; ++i)
{
string s;
cin >> s;
if (s == "
")
break;
S.PushStack(s);
}
I'm doing the same thing for char just replacing string with char.
I'm not sure what I am doing wrong but pressing enter does not end the program.
i just want to break the loop when user hit ENTER.But after that programm is stil working, i don't know why, becouse i have a code just like in book, i spend a lot of time with it.

I want to do simple program to capture some 5 surnames of people(employees) - using array and pointers. Well I understand a bit of arrays and I know how to loop through.
How can achieve this? This holds the key to my understanding how pointers work and can be used with char or strings.
I am working on a database project, which can store (initially) 10,000 marksheets with following capabilities
1) new entry
2) edit/modification of entry
3)delete entry
4) separate Departements ( BBA, BCS, M.Phil, Phd., etc.)
5) can store data on files ( initially, all data is stored in a single file)
Now, I want to create a menu, in which i can use arrow keys to navigate through the menu and use Enter key fo selection.
What should i use in it?? The project is only on C language.
Code:
struct lnode *ins_llist(char *data, struct llist *ll){
struct lnode *p, *q;
fprintf(stderr, "Data is %s when first entering ins_llist loop.
", data);
q = malloc(sizeof(struct lnode));
if ( q == NULL )
return(NULL);
}
[code]...
Trying to figure out a way to sort as i enter my data into the llist. What is in red and blue is what I've been messing around with to try and see if maybe i can get it to sort but it is not. When i flip sign, the order changes opposite, but i cant see how to sort each item as i go. Maybe i am too tired right now, lol, been working on this program for what feels like 30 of the past 24 hours haha.
I have task to make program.. To enter 10 positive numbers in an array. Find three numbers that stand near each other and that have the maximum sum.

Consider below statements:
int x;
scanf("%d", &x);
After running, It's supposed to enter an integer for x. what will happen if I enter a char instead of integer? which value will be in &x and x itself? I have a script and I get strange result while entering a char instead of integer for x.
How to write a code that will let me input how many variables I want.
Write a program that will enable you to enter a certain amount of values
Eg. 4
And then add the corresponding integers. Ex.
Choice: 4 12 34 56 78
The sum of the integers is: 180.
