C :: Obtain Check Number And Then Company Information From Datafile
May 13, 2013
I have to obtain a check number from a datafile and then also get company information also from a datafile.
So my first question is about the:
Code:
char outputFilename[]= "out.list"
Is this the name of the output file I'm going to write to? And also the file has to be created before being used...is that line of code creating the file or do i have to create it in notepad?
Code:
FILE *ifp, *ofp;
char *mode = "r";
char outputFilename[] = "out.list";
ifp = fopen("in.list", mode);
if (ifp == NULL) {
fprintf(stderr, "Can't open input file in.list!

Summary: 6 companies have a product in 5 different warehouses. Each company is identified by a positive ID number and each warehouse is identified by a number (1 for the first, 2 for the second,…)
Object: the object of this assignment is to write a C++ program which asks the user to enter a company ID number, and the number of products in each of the warehouses. It then computes and prints the total number of products for that company
If the total number of product is less than 100, it prints the message “place a new order”
Input: for each company, its ID, and the number of products in each warehouse with appropriate prompt messages.
Example: Enter company ID number: 101
Enter number of products in warehouse #1:30
Enter number of products in warehouse #2:60
Enter number of products in warehouse #3:0
Enter number of products in warehouse #4:5
Enter number of products in warehouse #5:27
The total for company 101 is:122
Output: for each company, the total number of product, and the message “place a new order” if the total number of product is less than 100.
Method:
1. Define global variable, int total_prod to hold the total number of products for a company
2. define the function void compute_total() that uses a loop to read the number of the products in all warehouses for one company, computer the total number of products and store it into the global variable total_prod.
3. Define the function void new_order() that determines if a new order need to be placed as follows: if the total number of products (in the global variable total_prod) is less than 100, it prints the message “place a new order”
4. Your function main does the following in a loop:
- read a company ID number
- call function compute_total() to read the number of the product in all warehouses for that company, and to compute their sum
- print the total number of the product for that company with an appropriate message
- call the function new_order() to determine if a new order need to be placed.

The code on lines 44-53 is suppose to display a message when the user enter a negative number, however, when a correct positive number is entered the message is display again.
#include<iostream>
#include<cctype>
using namespace std;
int main() {
char carType;
int A, B, C;

I can have at most 3 structs in array, but it could be 0,1,2 or 3 structs in array. I am trying to avoid dynamic memory allocation. I initialize sensors to 3 to reserve space for them in memory, since there may be at most 3 elements in the array. But I am testing a condition where there will only be 2 elements:
Code:
#include <stdio.h>#include <stdlib.h>
#include <string.h>
typedef struct {
unsigned long long int address;
float current;
unsigned char pressure_units;
} sensor;
[Code]...
The problem is even though there are only 2 sensors out of 3 in the array, sizeof(sensors)/sizeof(sensors[0]) returns 3. I assume because when it allocates memory for 3, it includes that allocated memory even though it really doesn't contain the struct. How can I figure out how many elements were really inserted into array, not just allocated to array?

I am making a number base conversion program in c++, suppose that user enters an base 2 number and want to convert that number in base 4. when he enter the number (which he wants to be converted), how can i detect that number is belongs to base 2 number system or not.
For example: if user enter 1001011001 , program should continue and convert that number to base 4. and if user enter 1200101 or 1001012 , program should not convert that number and output that this number is not belongs to base 2 number system.

My objective is to check to see if a number is odd or even and print it to the screen just to make sure its working correctly.
The data file contains:
138
402 2 485
9
43
98 805
58
421
948 7 97
48
67
35
42
948
579 39 12
700 20 500 210
98
I can get the numbers to print fine using:
fstream infile1(argv[1]);
if(!infile1.is_open())
cout << "Could not open file";
else {
char listNum;
while(infile1.get(listNum))
cout << listNum;
}
However, when I check for odd or even numbers it will check each and every number.
printed like this (partial list):
1 is odd 3 is odd 8 is even
9 is odd
But it should print:
138 is even
9 is odd
I tried using getline, but it keeps giving me the errors:
invalid conversion from 'void*' to 'char**'
invalid conversion from 'char' to 'size_t*'
too few arguments to function 'ssize_t getline(char**, size_t*, FILE*)'
Here is the getline code, what am I doing wrong? I have tried switching things around, adding things. Just nothing works.
ifstream infile1(argv[1]);
if(!infile1.is_open())
cout << "Could not open file";
else {
char listNum;
getline(infile1, listNum);
cout << listNum;
}

#define LENGTH 4
int main( void ) {
int i;
float a[LENGTH];
for(i=0; i < LENGTH; i++) {
scanf("%f", &a[i]);

How can I obtain the length of an array that has been sent throughout a function. In the following code, I obtain "2" as output, while I was expecting "5".
void call(int a[]) {
cout<<sizeof(a)/sizeof(int);
}
int main() {
int* a=new int[5];
call(a);
}
How can I properly call this function so I can obtain the correct array size?

I am trying to use fscanf to obtain a set of 14 or so strings per line, in a line where there are around 80 or so different sets of strings. I only need the first 14 and whenever I call scan f it starts at column 209 as opposed to column 1 where it should. Here's a sample of the code:
FILE *d;
d=fopen("t.dat","rb");
where a, n are all strings.
fscanf(d,"%s %s %s %s %s %s %s %s %s %s %s %s %s %s",&a,&b,&c,..(etc)..,&n);
A sample of the Input file looks like this:
USB270.15385-29.63146 270.153847 -29.631455 2.966699e+03 -9.99 1.300391e+03 -9.99 -9.99 A-A-- 6.787463e+01 -9.99 1.555773e+02 -9.99 -9.99 10100 | ----- ------ ------ ------ | 0.373 13.554 12.928 12.670 AAA | ----- -------- - -------- - -------- - -------- - | --- ---------- - ---------- - --------- - --------- - --------- - ---------- -

I was just reviewing some code, and my eye fell on a bit of regex that's intended to parse a date/time stamp into a date and time.
The timestamp uses shorted month names. The regex had all the possible month names to match the entire pattern. If it does, it went through a 2Nd loop to convert the month name into a 1 to 12 numeric value...
This made me wonder, since the regex is already doing the work to verify the alternation, can't it at the same time tell me which of the possible alternations it matched and use that to calculate the numeric value. So basically
Code:
std::regex reMonth("Some more regex stuff here (Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec).");
CString strTest("Some more regex stuff here Aug.");
std::cmatch res;
if (std::regex_match(strTest.GetString(), res, reMonth)) {
//int iMonthNum = res[1].something(); // some code here that returns 8 for Aug.
}
Or is there really no other way out than doing a 2nd level verification to figure out the actual month number. (The real regex is a bit more complex than this).

I'm using SQLBulkOperations to insert rows in bulk. I'm using SQLBindCol to bind the columns before SQLBulkOperations().
But how do I obtain the Identities? The bound buffer for the Identity column does not get filled after SQLBulkOperations()
At first I tried to use Bookmarks (column 0), but it seems that that is some other value (thought it would be filled with identities). But now I thought it must be that the bound buffer for the Identity column itself must be updated, but it's not happening. Maybe I need to do something extra?

I am facing a problem which i could not obtain the total numbers which is greater than the average value. For example:
#include <iostream>
using namespace std;
int main (){
int size , count;
double no, max, min ,total, sum , average;
[Code] ....
In this case im able to compute the average of the numbers but when it comes to capture the total of numbers which is greater than the average value, how to compile the code , because the average number is only been compute once all the value capture by the input of user is sum up.

Make a c++ program of the payroll of a company
input values :
a. Name of Employee
b. Position in the company
c. No. of hours worked
d. No. of overtime hours
e. rate per hour
formula:
basic pay = number of hours worked x rate per hour
ot pay = overtime hours x 150% of rate per hour
gross pay = basic pay + ot pay
tot deduc = tax + sss + med
tax can be computed based on the following table:
basic pay tax
10000 or less 1% of basic pay
10001-15000 2% of basic pay
15001-20000 3% of basic pay
20001-30000 4% of basic pay
30001 or more 5% of basic pay
sss = 10% of basic pay
med = 6% of basic pay
net pay= gross pay - total ded
*The payroll should have at least 5 employees in it.*

I'm trying to get this program to return total taxi cab fair an infinite number of times, however, when I use the while statement after for and try to run the program, it just keeps displaying the first total fair rapidly.
specifications:A cab company needs a program to calculate the cost of a cab ride.
The driver will enter the length of the trip in miles.
The miles entered must be greater than 0.
Create a function to calculate the charge. The function should receive one argument, the length of the trip, and should return the total fare for the ride.
The taxi charges a fixed charge of $2.50, plus an additional charge of $1.85 per mile.
Allow the user to calculate any number of trips.
At the end display the total of all the fares.
here is my code:

My colleague and I have been given a task to create a list with the employes of a company using binary trees. Each employee/node has to contain the following information:
- Employe name
- Rank
- ID Number
- monthly Salary
We have to write a C program (using Codeblocks) which builds the company tree with the information above and afterwards lists all the employes who have a salary bigger then a number specified by the user.
So far so good. We've had a look on the examples on the internet and after finding one which looked friendly enough we started working on that one to suit our needs. Credits for the original source code to: C Program to Implement Binary Search Tree Traversal - Basic C Programs | C Programming Examples
We've reached the point where we're able to insert the required information but being able to list all the employes who's salary is bigger then the number given by the user seems to be rather difficult to achieve. I'll include the code next. We have left almost the entire pieces of the original code and we are aware that the are still things which are not required for our assignment, which only requires to enter the 4 information above and afterwards display the employes with the before mentioned condition concerning their salary.
Code:
# include <stdio.h>
# include <conio.h>
# include <stdlib.h>
typedef struct BST

You are writing a program to calculate the area for 500 different measurements for a playground company in the region. The company must calculate square footage of each prospective playground, as well as the total cost to mulch each area. The cost of mulch changes frequently, so the company would like to be able to input the current cost per square foot of mulch each time they run the program. Since the quantity of data is large, the input should come from a file called “measurements.txt”. You can assume the file includes the length of each prospective playground, followed by the width. The file will be in the following format.
450300
120210
.
.
.
Ask the user the name of the file they would like to write to, as well as the current price of mulch per square foot. Output the area of each playground, along with the total price of mulch to the file that the user specifies. The playground company would like each column of output to be 20 characters in width. Each column should have an appropriate heading in the output file. You should format your output data appropriately. For example, for the input data displayed above, along with a $2.00 per square foot mulch price, the output would be:
Area Total Mulch Price
135000 $270000.00
25200 $50400.00

This program in not completed. I am creating a large program in order to calculate a company's weekly payroll. For now I am filling in the separate functions piece by piece before the rest of the program is completed.
Right now I am trying to use separate functions to call other functions. I need to ask the user for the file name and then open the file. I am no longer getting any compiler errors however when I run the program all it displays is "Welcome."
So it's not actually calling the NameTheFile function and the OpenTheFile function. It just says "Welcome" and then closes down. Why is it doing this?
/*Program to determine company's weekly payroll*/
#include <iostream>
#include <string>
#include <fstream>
