Visual C++ :: Convert MM/DD/YY Hh:mm Stream To Integer?

Nov 7, 2012

I'm trying to read in two instances of date and time (from user input) into a string value (MM/DD/YY hh:mm).
I need to be able to calculate the difference between the two in order to return how much time has elapsed from the first date/time to the second date/time.

What would be the most efficient way to go about obtaining said results?

I was thinking I need to convert each year, month, day, hour, and minutes into its own integer variable, after researching immensely online I'm still not sure how to convert from a string of characters to an integer.

Visual C++ :: File Stream Change Its Address During Writing Text Contents To The Stream

Apr 29, 2013

I wrote a program to write text contents to file stream through fputs, the file stream address was changed in the middle of writing text content to the stream (11% text content have been put into the file stream), that cause the file stream pointer can be evaluated problem and raise exception on stream validation code in fputs library function, my question is what things could go wrong to make file stream pointer changed its address to something else or a NULL pointer if the file stream have not been flushed and closed.

C/C++ :: Convert Integer To Its 2 Complement

Feb 12, 2014

I have to implant a code to convert any integer to its 2'complement. I have already finished the first and the second part, which was to convert the integer to its binary representation, then to invert each digit in the binary representation. The third part is to add 1 to the binary representation.

// the last step is to add 1 to the binary number
int carryIn=0;
int carryOut;
for(itr= bainaryList.begin(); itr!= bainaryList.end(); itr++) {
//start comparing the possibilities of the values in both lists
if (((*itr)==0) && (carryIn== 0))

C++ :: Convert From Integer To Character String

Oct 2, 2013

I have been trying to write a function which can convert a number from an unsigned long integer to a readable ASCII character string. this is what I have come up with, but I am receiving some very strange characters in return. Could the problem be that I am telling a char to = an unsigned long int, (cString[i] = product[i])?

void convertToString(unsigned long con) {
unsigned long product[10];
char cString[10];
const unsigned long begConvert = 10 ^ 10;

Visual C++ :: Stream Data From System Windows Controls

Dec 19, 2012

I need make a CBitmap or a streamdata from a System.Windows.Controls::Image(rendered out put)in a SDI mfc application (supporting clr). Here is my codes:

Code:
using namespace System;
using namespace System::IO;
using namespace System::Collections::Generic;
using namespace System::Windows;
using namespace System::Windows::Controls;

[Code] .....

By this codes i can read datastream from bitmapSource but in this way somthing goes wrong in most of GIF animations. After debug i found out i need 3 more things too decode a gif animation - (x,y) position and size of each frame and disposal method for each one - finally i just found a way to draw tru images on a form window by this codes:

Code:
System::Windows::Window^ mainWindow;
mainWindow = gcnew System::Windows::Window();
mainWindow->Title = "GIF Imaging Sample";
//ScrollViewer^ mySV = gcnew ScrollViewer();
array<System::Byte>^ pixels = gcnew array<System::Byte>(bitmapSource->PixelHeight * Stride);

[Code] ...

When i change

Code: bitmapSource = decoder->Frames[0];
to
Code: bitmapSource = decoder->Frames[01];

frame[1] has drawn perfectly on window(i think some how Image class takes care about - (x,y) position and size of each frame and disposal method for each one ),so im wonder if how can i make a CBitmap or a data stream from System.Windows.Controls::Image class to use in mfc app.

C++ :: Convert Positive Integer Into Its English Name Equivalent To Digit?

Jul 13, 2014

convert a positive integer code into its english name equivalent for digit. A valid code is of size between four (4) to six (6) digits inclusive. A zero is not allowed in the code.

example : if the input is 234056 the output is : INVALID CODE (PRESENCE OF ZERO)
if the input is 23456 the output is : TWO THREE FOUR FIVE SIX
if the input is 9349 the output is : NINE THREE FOUR NINE
if the input is 245 the output is : INVALID CODE (3 DIGITS)
if the input is 2344567 the output is : INVALID CODE (7 DIGITS)

step 1 : input code
step 2 : count the number of digits in the code
step 3 : if there is a zero in the code, "INVALID CODE (PRESENCE OF ZERO)" go to step 4
step 4 : if number of digits is mode or equal than 4 and less or equal than 6, go to step 5 else display the following message "INVALID CODE (<number of digits> DIGITS)
step 5 : call a function called digit_name to convert each digit into its
equivalent english name. display the result
step 6 : print the digits in reverse order
eg; if input is 13453, reverse order is 35431

C :: Accept Input Number From User And To Convert It Into Array Of Integer

Oct 7, 2014

i was trying to solve a problem in SPOJ and what i wanted to do is to accept an input number from the user and to convert it into a array of integer.

Code:

#include<stdio.h>
int * toarray(int *num);
int main(void)
{
int testCases;
}

[code]....

But whenever i try to print the array in the main function i get only two value and the rest address

Code:

1//number of testCases
23456 //input number
6
2293452
4
2293700
1974439125

Process returned 0 (0x0) execution time : 4.152 s
Press any key to continue. However, if i tried to print the array from within the function, it prints the numbers just fine.

print the array elements from the main program, so that i would be able to go on with the rest of it

Visual C++ :: Check If Input Is Integer Or Not

Jun 20, 2014

I have been trying to make a very simply programme that checks if the inputted information is an integer or not (i.e: that it contains no other characters).

I have tried using the isdigit function (but this only works for single characters). I have tried cin.clear, cin.ignore (1000) but this doesn't work either..

Any effective way to check if x in the following programme has been entered correctly

#include <iostream>
using namespace std;
int main() {
cout << "Please enter an integer (positive or negative)" << endl;
int x;
cin >> x;
HERE I WOULD LIKE CODE TO CHECK IF THE USERS INPUT IS VALID
