Too Few Arguments & Expected A Declaration - c++

Question

I can't seem to figure out what is wrong with a game hack that makes the character auto jump for faster movement and I may sound very to dumb to what easy of an error it probably is so if anyone could help me that would be much appreciated!
#include <Windows.h>
Memory Mem;
#define key_space 0x20
#define key9 0x39
#define key_sc 0x0A
void bhopFunc();
const DWORD localBase = 0xA6C90C;
const DWORD flagOffset = 0x100;
void bhopFunc() {
int FL_ONGROUND = 257;
Mem.Process("csgo.exe");
DWORD ClientDLL = Mem.Module("client.dll");
}
if (GetAsyncKeyState(key_space) & 0x8000 && m_fFlags == FL_ONGROUND) {
keybd_event(KEY9, KEY9SC, 0, 0);
keybd_event(KEY9, KEY9SC, KEYEVENTF_KEYUP, 0);
}
int main()
{
while (true) {
bhopFunc();
}
}
}

Answer 1

The 4 lines of code above int main() are supposed to be inside your bhopFunct() function.
Here is your code fixed:
#include <Windows.h>
#define key_space 0x20
#define key9 0x39
#define key_sc 0x0A
void bhopFunc();
const DWORD localBase = 0xA6C90C;
const DWORD flagOffset = 0x100;
void bhopFunc() {
int FL_ONGROUND = 257;
Mem.Process("csgo.exe");
DWORD ClientDLL = Mem.Module("client.dll");
if (GetAsyncKeyState(key_space) & 0x8000 && m_fFlags == FL_ONGROUND)
{
keybd_event(KEY9, KEY9SC, 0, 0);
keybd_event(KEY9, KEY9SC, KEYEVENTF_KEYUP, 0);
}
}
int main()
{
while (true)
{
bhopFunc();
}
}
