I don't see you using sort in your code.
Also, any insertion or deletion in the list renders the iterators invalid.
This can give you unexpected results.
|
|
|
|
|
Do you know of any better way to approach this scenario? Sort those objects in acending order by within a list?
Thanks.
|
|
|
|
|
The best approach is to use TempList.sort(MyCompare<RDLRun*>());
Here MyCompare is a functor used to decide how to sort the list of RDLRun class pointers.

Thanks for the insight. I have create a little functor to work with the sort function but getting an error. there is something that I am not doing right. Thanks for your help. 
Functor code:
bool RDLTemporaryResource::SortByTime:public std::binary_function<RDLRun*, RDLRun*, bool>
{
bool operator() (RDLRun* a, RDLRun* b) const
{
if( a->GetDepartureTime() < b->GetDepartureTime() )
return 1;
else return 0;
}
}

1) Write the data to the printer (driver) using code.
2) Write the data to a text file, and use ShellExecute(hWnd, "print", "data.txt", ...) on that text file. This will default to Notepad, but you can specify Winword.exe instead.
3) Use Word Automation.

An exe uses a dll file.
If only code inside function body of the dll file was changed (no functions were added or deleted and function signitures were not changed), but exe itself was not re-compiled, may the dll cause any dangrous (or problem) for the exe file?
the Q related to software auto-updates.
For lite reason, I don't want to update exe when update dll.

As long as the function signatures which are called by the executable are the same there should be no problems. You can even add resources or additional functions without any problems.

Hi,
It is safe to change the internal implementation of the exported functions, as long as you retain the signature. It is also perfectly safe to add more new functions, but you should not remove an existing function that may be used by the executable.

Yes that is safe, also see binary compatibility[^] for more background on the topic.

hello, i am having a problem with this code. I do not know what is wrong. I enter the begbal, the ourdep and the withdraw. But in the end when goes to get the final balance. The answer is always the same as the input of begin bal. Any help would be greatful.
#include <stdio.h>
#define SENTINEL 0
float endbal,
finbal;
int date,
outdep,
withdraw;
int main (void)
{
printf("BANK RECONCILIATION FOR: 10/21/98");
printf("\n\nEnding balance on statement:");
scanf ("%f", & endbal);
printf("Enter Outstanding dep (or %d to quit)>", SENTINEL);
scanf ("%d", & outdep);
while (outdep!= SENTINEL)
{
finbal = finbal + outdep;
printf("Enter outstanding dep (%d to quit)>", SENTINEL);
scanf("%f", & outdep);
}
printf("Outstanding check/withdrawal (or %d to quit)>", SENTINEL);
scanf ("%d", & withdraw);
while (withdraw!=SENTINEL)
{
finbal = finbal - withdraw;
printf("Enter withdrawal (%d to quit)>", SENTINEL);
scanf("%f", & withdraw);
}
finbal = endbal + outdep - withdraw;
printf("Your final balance in your checkbook should be $ %f" , finbal);
return 0;
}

I made the changes and did the execute, this is what came out. still not the right answer. I do not know what else to do with this. I have tried so many things.
BANK RECONCILIATION FOR: 10/21/98
Ending balance on statement:20
Enter outstanding dep (0 to quit)>10
Enter outstanding dep (0 to quit)>10
Enter outstanding dep (0 to quit)>10
Enter outstanding dep (0 to quit)>0
Enter outstanding dep (0 to quit)>0
Outstanding check/withdrawal (or 0 to quit)>10
Enter withdrawal (0 to quit)>10
Enter withdrawal (0 to quit)>0
Your final balance in your checkbook should be $ 2185232384.000000
"c:\cop2000\a5\lcc2\score.exe"
Return code 0

Well, I didn't notice you made a bad mix of floats and ints.
Try
#define SENTINEL 0
int endbal,
finbal,
date,
outdep,
withdraw;
#include <stdio.h>
int main (void)
{
printf("BANK RECONCILIATION FOR: 10/21/98");
printf("\n\nEnding balance on statement:");
scanf ("%d", & finbal);
printf("Enter Outstanding dep (or %d to quit)>", SENTINEL);
scanf ("%d", & outdep);
while (outdep!= SENTINEL)
{
finbal = finbal + outdep;
printf("Enter outstanding dep (%d to quit)>", SENTINEL);
scanf("%d", & outdep);
}
printf("Outstanding check/withdrawal (or %d to quit)>", SENTINEL);
scanf ("%d", & withdraw);
while (withdraw!=SENTINEL)
{
finbal = finbal - withdraw;
printf("Enter withdrawal (%d to quit)>", SENTINEL);
scanf("%d", & withdraw);
}
printf("Your final balance in your checkbook should be $ %d" , finbal);
return 0;
}

None of the values have been initialized and it always causes problem as the programs works on a random garbage value.
1. endbal is not initialized. Either set it to 0 or some other positive value at the start of your program.
2. finbal must be set to 0 at the start of main() function.
You can initialize these at the time of declaration : float endbal = 0, finbal = 0;
Also the statement finbal = endbal + outdep - withdraw; is wrong. You have already added deposit amount and subtracted withdrawn amount in the variable finbal. So all you need is endbal = endbal + finbal.
Finally, you are displaying the wrong value. You should display endbal in the last printf statement.
I hope this helps you.

sorry, but that is horrible code.
you have amounts in int and float types, it might be wise and safe to be consistent.
you have an int withdraw yet you fill it with a %f in scanf.
you have two balance variables, you only need one.
you don't initialize variables that need it.
you have duplicated several lines, indicating you have chosen the wrong loop construct (use a do while instead!)
and what happens when the input isn't a number (say an empty line, or some text)?

Hi,
not tested:
float getNumber(char* prompt, float* delta) {
float number;
printf(prompt);
scanf("%f", number);
... add whatever checking you consider important
*delta=number;
return number!=0;
}
int main(void) {
float balance, delta;
int more;
printf("BANK RECONCILIATION FOR: 10/21/98");
printf("\n\nEnding balance on statement:");
scanf("%f", &balance);
do {
more=getNumber("Enter Outstanding dep (or 0 to quit)", &delta);
balance+=delta;
while(more);
do {
more=getNumber("Outstanding check/withdrawal (or 0 to quit)");
balance-=delta;
while(more);
printf("Your final balance in your checkbook should be $ %f" , balance);
return 0;
}

I'm sure someone can, but the question is will they? In the interim, read #2 and #4 here.

hi,
I have a defined a function template as follows.
template<typename T, typename Function, typename K>
std::vector<K> find( std::vector<T> &a, Function _predicate )
{
std::vector<K> b(a.size());
//... some Code ..//
return(b);
}
which gives a compile error when i try to compile it using VC++
stating that it cannot deduce argument for parameter K.
I have attached the sample code below,
any suggestions from anyone?
Thank you
/********* File main.cpp **********/
#include <iostream>
#include "prog.h"
int main()
{
std::vector<int> a(10);
for( int i = 0; i < 10; i++)
{
a[i] = i;
}
std::vector<int> b = find( a, is_true<int>() );
for( int i = 0; i < 10; i++)
{
cout << "Value " << i << " : " << b[i] << endl;
}
}
#indef PROG_H_INCLUDED
#define PROG_H_INCLUDED
#include <vector>
//Function Predicate to check whether a value is true
template <typename T>
class is_true
{
public:
is_true()
{}
bool operator() (const T &element) const
{
if( element )
{
return true;
}
else
{
return false;
}
}
};
//Function Predicate to check whether a value is true
template <typename T>
class is_false
{
public:
is_false()
{}
bool operator() (const T &element) const
{
if( !element )
{
return true;
}
else
{
return false;
}
}
};
template<typename T, typename Function, typename K>
std::vector<K> find( std::vector<T> &a, Function _predicate )
{
std::vector<K> b(a.size());
for( int i = 0; i < a.size(); i++ )
{
if( _predicate(a[i]) )
{
b[i] = K(a[i]);
}
}
return(b);
}
#endif // PROG_H_INCLUDED

You cannot do that (as the message clearly states). An option would be making vector<K> an out argument, i.e. for instance:
template<typename T, typename Function, typename K>
void find( std::vector<T> &a, Function _predicate, std::vector <K> & v)
{
v.resize(a.size());
for( unsigned int i = 0; i < a.size(); i++ )
{
if( _predicate(a[i]) )
{
v[i] = K(a[i]);
}
}
}
and then
int main()
{
std::vector<int> b;
find( a, is_true<int>(), b );
}
