Write your question here. Hello World not working they say 1>------ Build started: Project: HelloWorld1, Configuration: Debug Win32 ------ 1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
I used this video [URL] ....
#include <iostream> using namespace std; int main(){ cout <<"Hello World! " << endl; return 0; }
Under visual studio, this is a typical run time error,
Code: void func(int x){ x = 3; } int main() { int x; func(x); }
When x is passed to the function func, it is not initialized. But my question is that why it should be an error? On the other hand, if I change the definition of func a little bit like this,
Code: void func(int& x) { *x = 3; } int main() { int x; func(&x); }
Now in main, x is still not initialized, but this time there isn't a run time error like "the variable is being used without being initialized. Why?
run-time check failure #0 - the value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention
when i try to run my code. It has compiled fine on another computer, but it simply will not work on this one. This is the part of code where it is receiving the error. it has to do with the stoi
Code: #include <string> // for use of string #include <fstream> //for file handling #include <iostream> // for file handling #include <cstdlib> #include <iomanip> //for the setprecision used further below using namespace std; struct MasterData //struct created named 'MasterData' to hold one line from master file
I'm trying to make OBJ converter. The file structure of which I am trying to convert is an XML structure. Here's an example. I currently have a lua script that does this for me. But it always crashes on big objects. It's for a game called "ROBLOX" The only information I need to convert is.
<int name="BrickColor">194</int> <-- Brick Color <CoordinateFrame name="CFrame"> <-- Position <X>0</X> <Y>0.600000024</Y> <Z>0</Z>
And
Vector3 name="size"> <-- Part size. X>1000</X> Y>1.20000005</Y> Z>1000</Z>
Here's the lua script. [URL] .....
This currently grabs all of the ClassNames in the place and converts them to OBJ wavefront gemotry.
I have a problem in using ATL 7.0 string conversion macros.
My codes looks like this, which uses ATL 3.0 string conversion macros in the past:
Void Myfunc() { USES_CONVERSION;
LPSTR lpszA; LPWSTR lpszW; If (...) { CString strText; If (...) { If (bUnicode)
[Code]...
But since 3.0 macros do not support large strings, I want to switch to 7.0 macros, but have problems. Based on the [URL]... samples, I should declare CT2A pszA(strText) or CT2W pszW(strText) within the if and else bodies, as below:
However, in such a case, after running to the codes using lpszA or lpszW, both CT2A and CT2W will be destructed so lpszA and lpszW will be invalid. How to solve this problem?
I have a project that is essentially a hot pot of C/asm (naked functions etc). The code gets injected into another EXE. It works fine when compiled in Visual C++ 6 but when compiled in Visual Studio 2008 it compiles fine but falls over in use.
Are there certain settings I need to look out for? I have optimization disabled and as far as I can tell the command line options for compiler/linker are the same (given the differences).
I have opened both builds in IDA and the 2008 build has more import and offset jumps are in different places.
Processing time for the above code takes 9500 to 9900 microseconds (Used QueryPerformanceCounter).
Code: TempArr[0] = ((BYTE*) pvData) [0];
This code takes 1100 to 1200 microseconds. My doubt is, The processing time of PVOID data into byte array conversion takes time like above? Or any other easy way(PVOID data into byte array conversion) to reduce the processing time?
I'm expected to write a c program for this question :
Using these header files #include <stdio.h> #include <conio.h>
Question : Write a program that will prompt the user to enter an integer value and a character code to indicate whether they want to do a Kilogram to Pounds conversion (A) or a Pounds to Kilogram (B) conversion. Note that 1 kg = 2.2 pounds. The program should then do the necessary conversion indicated by the code and display the newly converted value to the screen.
Say I have a class that requires dynamic allocation to implement a few of the operators. Take "+" for example; I need to create a new object to hold the sum of the two parameters whose size is not known at compile time.
I'm pretty sure the standard way to indicate a failure inside the overloading function would be to throw an exception. However I am currently involved in an embedded(ish) project where the spec. says no exceptions are to be used.
I think I have 2 options:
1. Return an "invalid" object (with a flag indicating an error has occurred) and check for this after each operation.
a = b + c if (a.err) // handle error or
2. To forsake operator overloading entirely and think up a new way of doing things where all functions that involve dynamic allocation can return error codes. but this seems rather terrible too as I may end up with something like:
objA a if (add(&a, b, c) == -1) // assuming b and c are initialized before this snippet starts // handle error
Is there a number 3 that I haven't thought of? It seems that not allowing exceptions is fairly common even in the non-embedded world [URL] so how is this normally done? or is operator overloading usually avoided when exceptions are not allowed?
I am having trouble with the array pointer and with the variables. I don't seem to have the pointer set up because the additional times the array is called it is empty. Also, if I don't use integers the program drops through. where I am going wrong?
Question is in the code
/* NumClass Main.cpp ******************************************************************************************* * * Design a class that has an array of floating point numbers. The constructor should accept an integer argument and dynamically allocate the array to hold that many numbers. The destructor should free the memory held by the array. In addition, there should be member functions to perform the following operations: * **Store a number in any element in of the array
I am looking for a math/big num library, that allows me to convert 32/64/80 bot float numbers to string and vice versa.
Precision & accuracy is of importance here, and since this is an IEEE standard, i have high hopes that there are libraries for this out there, which would save me the hassle of trying to implement this myself...
I am having trouble in creating a program (named "up.c") that should do the following:
- if you run the command ("up") with no arguments, it should read input from stdin and display it on stdout, converting lowercase letters to uppercase.
- if you run the command with one or more files (as arguments to the "up" command), your program should read input from each file and display it on stdout, again converting lowercase letters to uppercase.
I'm trying to create a single program that can do both of these, and handle errors gracefully. I've found that some codes work to convert the letters, but they seem overly simple and aren't giving me what I'm looking for in my program.
I have a question on conversion between char & string. I have cut & pasted the part of the code from my C++ code and my function "decryptPwd" uses C style code with "char" etc.
I need to pass a string (mypwd) somehow to this function after conversion & then compare it to another string (newmypwd).
I tried - "decryptPwd(mypwd.c_str())==newmypwd.c_str()" but it did not work.
.. #include <string> .. char* decryptPwd(char hash[64]); main () { string mypwd; string newmypwd; if (decryptPwd(mypwd)==newmypwd)
