PBYTE(inAddr)^ := $E8;
PDWORD(inAddr + 1)^ := rMemAddr - inAddr - 5;
I need convert code to c++, but i do not know about Pascal, pls help me, thanks！
I tryed, but the two line code is wrong.
Taking a guess I would say
*(uint8_t*)inAddr = 0xE8;
*(uint32_t*)(inAddr + 1) = rMemAddr - inAddr - 5;
I do remember that ^ is the indirection operator in Pascal and := is the assignment operator.

After taking those values I have to store the values in two different arrays (say x and y)
So the only error I can immediately see is this
float* a = NULL;
a = new(nothrow)float;
which should be
float* a = new float[count];
Your version only allocates enough space for a single float when you really need space for count floats.
When you have code that isn't working, and you want to ask a question about it you really should say exactly what happens when you run the code. Doing this will help get you better answers.

If you are using C# the you can use this code
txt=Regex.Replace(txt.Replace("_",""), #"\.\w+", "");

I have a simple formula and I want to use it in C++ application.
Not sure how to rewrite in C++.
logn(5, abs((a*b - d*c) / (tan(c) + sin(d))))
where logn is:
double logn(double base, double x) {
return log(x) / log(base);
}
and the header cmath is included for the other functions.
You can do this, be careful with libs, namespaces, and radian arguments
z = a*b - d*c;
s = tan(c) + sin(d);
num = abs(z/s);
log(num)/log(5);

I’m very new in C++ and I need your help. I want to use the input value as a mathematical function then print the result.
What i need is:
When user input: 2 +1 and hit Enter then output (cout>>)
should be your result is: 3 (the sum of 2 + 1)
The mathematical symbol could be + or * or / or -.
Could you please help me with some example?
Thanks in advance!

I would like to be able to convert a string such as "(5+6)*6" and get the resulting integer from that equation. It is important that it starts out as a string.
You can use library fastmathparser for c++.
In link is example how use this library.
If you really want write alone this parser, I recomended use Shunting-yard algorithm
