C++ :: How To Convert Char Into Numeric Value

Jan 1, 2015

when I was looking for a way how to convert char into numeric value for std::cout I found some old discussion with this statement: Operations on unsigned int are typically faster than on unsigned char, because your processor cannot fetch single bytes but has to get at least a multiple of 4 and mask out the other 3 bytes. Is this true? By using smaller (in bytes) variable I actually slow down my program? I always thought that it is a good practice if I use the smallest variable which will do the work. Is it also dependent on a compiler and OS?

C# :: Possible To Convert Char Into Numeric Value

Feb 22, 2014

I want to avoid converting the char[] into a string as an intermediate step, since I'm trying to write some "string" parser helpers which don't allocate a bunch of different strings onto the heap. (whole point of this little project is to reduce GC pressure in applications that do alot of string parsing).

basically if I have a char[] that contains {'1','2','3'}, I'd want to to be converted into 123.

I tried messing around with the stackalloc operator in C#, but its illegal to stackalloc a string unfortunately. I also googled around for converting a char[] into a numeric value, but all the solutions convert each individual char into their ASCII code, or convert the char[] into a string as an intermediate step.

C# :: Creating Object That Uses Numeric Up / Down And Track Bar?

Nov 19, 2013

I want to create an object that uses visual C#'s Numeric Up/Down and a Track bar.

The reason is that I have a GUI that uses lots of these linked together with events and I want a common event handler for all of them.

Maybe just adding a property that is a Numeric Up/Down in the Track bar and vice-versa will allow me to create a common event for all of these pairs.

C Sharp :: Numeric Up Down Hides Its Value From The User

Oct 17, 2014

I have a button which selects a particular tab and tab page on a form. This tab page has an embedded tab control with several more pages.

When I click on this button, the desired tab page is selected, but the NumericUpDown value (which is on the tab page) is not visible. The value is the current year.

Could it be that somehow, the click event for the button is hiding the value?

C++ :: How Can Numeric Values Stored As Strings Be Converted To Numbers

May 16, 2013

I need to check my understanding from some questions about strings. How can numeric values stored as Strings be converted to numbers?

a)vector of required numeric data type
b)atoi function in cstdlib library
c)cout statement with required numeric data type

I picked b), I am aware of atoi, atol, and atof as methods to convert, but are there other methods?

What is the purpose of strncat function?

Combines n characters from source string into target string

C++ string provides:

a)convenient way to declare and manage character arrays
b)functions to manipulate strings
c)all of the above
d)none of the above

I picked c)

C/C++ :: Read In Numeric Representation Of Date And Prints It Out In Formatted Manner

Oct 13, 2014

Write a program that reads in the numeric representation of a date and prints it out in a formatted manner as the box below.

1. If the user entered an invalid number for the month it should display "Invalid Month"
2. If the user entered an invalid number for the date it should display "Invalid Date"
3. Check to see if the day is outside the range for that particular month

An example of the input and the output:
Enter the date: 1 24 2013
The date you entered is: 1242013

Im not sure on how to go about this problem, but this is what I have.

#include <stdio.h>
int main(void) {
int a, b, c;
int status;
printf("Enter the Date");
status = scanf("%d,%d,%d",&a, &b, &c);
printf(" The Date is : %d",status);
return 0;
}

Am I going about this right? Is there an easier or better way to go about it? All that happens is that the program reads the first number and spits that back out.

C++ :: Forward Declaration Location

Jun 6, 2012

Any difference between

Code:
class SomeOtherClass;
void foo(SomeOtherClass* p);

And

Code:
void foo(class SomeOtherClass* p);

I was told that "2" would limit the scope of the forward declaration to the declaration of foo... However, after testing it, it appears that both behave the same...

C++ :: Access Violation Reading Location

Feb 1, 2014

I recently started learning C++ and wanted to deep a bit into process memory reading for Windows, but I get an error I don't know how to fix. I'm using Visual Studio Express 2013 as my IDE and it tells me this, when I try to run and debug:

"Unhandled exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043."

The Call Stack window says following:
ntdll.dll!_NtRaiseException@12() Unknown
ntdll.dll!_KiUserExceptionDispatcher@8() Unknown
ntdll.dll!_RtlInitUnicodeString@8() Unknown
> readProcessMemory.exe!main() Line 8 C++
[External Code]

And in the Output window is this: First-chance exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043. Unhandled exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043.

My code should be extremely simple, I'm just trying to find a Windows window. But here's the code.

Code:
#include <windows.h>
#include <iostream>
using namespace std;
int main(){
