Remove string from process memory using Adress

Question

I want to remove string from one of the process with adress method. I got a ProcID and tried to get adress with which I can to change all string of process memory, but something doesn't enough. I know that it isn't a full code of this remover but i can't to search more info on this topic for C++

int procname;  
uintptr_t adress;  
string ValueToWrite;  
  
int main()  
{  
	SetConsoleTitle("String Remover");  
  
	cout << "Enter process PID: \t";  
	cin >> procname;  
	cout << "\n" << "\n";  
  
	HANDLE hProc = OpenProcess(PROCESS_ALL_ACCESS, 0, procname);  
  
	if (!hProc)  
	{  
		cout << "Iinvalid PID.";  
		return -1;  
	}  
	else  
	{  
		cout << "Process succsesfully opened." << endl;  
		cout << "\n";  
	}  
  
	SIZE_T BytesToWrite = ValueToWrite.length() + 1;  
  
	cout << "Enterr adress: \t";  
	cin >> adress;  
	cout << "\n" << "\n";  
  
  
	if (ReadProcessMemory(hProc, (void*)adress, (LPVOID)ValueToWrite.c_str(), BytesToWrite, 0))  
	{  
		WriteProcessMemory(hProc, (void*)adress, (LPCVOID)ValueToWrite.c_str(), BytesToWrite, 0);  
	}  
	else  
	{  
		cout << "Invalid adress.";  
		return -1;  
	}  
}  

I tried to ReadProcessMemory after PID that program could to check about process strings. I had an idea to "if person will enter adress and it will be check by ReadProcessMemory and it will not invalid adress => WriteProcessMemory (i wanted to change by this function all string and it will be change it).
Maybe i should to add some functions. Can you help me with this and tell me what to do?
I recently started to learn about process memory so don't be so angry for me

Hi, @Vadym Sydorchuk

You could refer to the similar thread's answer.

you have to fill the difference in character length with \0.

It is not recommended that writing string into memory.
