Do anybody have c notes I require
Anonymous
thanks😅😅.. I was just trying to understand this.. I'm somewhat new to it
This is used to prevent format string vulnerability. Instead of writing
printf(i)
you need to write the code above because the attacker can insert malicious input to an "i" theoretically
Anonymous
If you will write printf("%x \n", i), you will get a hexadecimal form of number in i
Kaashᅠ
i got it😃
Kaashᅠ
It's C language?

Yes

ohh i see, printf is written there

Hi all, i'm newmember. Nice to meet !

i have tried porting this code from c# to c++ , but failed many times , can someone help me learn ?
————————————
public float ReadFloat(int MemoryAddress)
{
byte[] buffer;
return this.ReadMem(MemoryAddress, 4U, out buffer) == 0 ? 0.0f : BitConverter.ToSingle(buffer, 0);
}

What have you tried so far?
float GetFloatTest(DWORD offset) // OK
{
DWORD OldProtect;
float Value;
VirtualProtect((void*)offset, 4, PAGE_EXECUTE_READWRITE, &OldProtect);
if ((*(float*)(offset)) > 0.0f)
{
Value = *(float*)(offset);
}
else
{
Value = 0.0f;
}
VirtualProtect((void*)offset, 4, OldProtect, &OldProtect);
return Value;
}

Assuming this.ReadMem just reads n bytes from the address, this looks correct.

this is Readmem
public int ReadMem(int MemoryAddress, uint bytesToRead, out byte[] buffer)
{
IntPtr num = ProcessMemoryReaderApi.OpenProcess(56U, 1, (uint) this.m_ReadProcess.Id);
if (num == IntPtr.Zero)
{
buffer = new byte[0];
return 0;
}
buffer = new byte[(IntPtr) bytesToRead];
IntPtr lpNumberOfBytesRead;
ProcessMemoryReaderApi.ReadProcessMemory(num, (IntPtr) MemoryAddress, buffer, bytesToRead, out lpNumberOfBytesRead);
ProcessMemoryReaderApi.CloseHandle(num);
return lpNumberOfBytesRead.ToInt32();
}
Nessie
will this cause me to convert it ?

Looking at this, is seems like you are reading the memory from a potentially different process. In this case you need the OpenProcess and ReadProcessMemory functions

Can someone tell me what's the use of setConsoleColor ( )
Anonymous
It's bitwise operator
Yes but booleans implicitly get converted to 1 or 0. So bitwise & has the same behavior as logical &&.

Because I think it doesn't make any difference, because you're checking for 0 or not 0...

In that case, both are AND (one logical and one conditional)
But they have different meaning and might result in different code (hopefully it's optimized and then it's the same code)
Anonymous
But for conditional shit u should use the conditional one (&&).

i know about competitive programming but not exclusively about C++

it's about graph, dynamic programming, arithmetic...

This is quite a meta questions, do you really just want to know if there are competitive programmers who code in c++ or something else?

hey guy's
what will this code do
if ( gender ! = ' m ' && gender ! = ' M ' && gender ! = ' f ' && gender ! = ' F ' ) {
return false;
}
Prince Fine
Should it be && or ||
Prince Fine
Depends on what you want to say
what i want to do was if the user enters
' m ' or ' f ' or ' M ' or ' F ' it will return true
Prince Fine
if not false

Write a recursive function that find the numbers of letters in a given word.

Not required if you have a single function to execute.

Like, we have to use two Couts in if statement..
Will have to use braces or not?

Yes, then you have to but he is using 1.

The only form of competitive programming I partake in is the IOCCC and my code read like an OCR of Mesopotamian clay tablets done with a software that only supports NASDAQ company codes

don't u think it's easier if we send screenshots than writing
yeah it's easier but, Just to prevent spam or filling up storage is the reason behind, i think

Hey what are constant, volatile and constant volatile variables
