How to write data to a process/memory?

Okay so I'm making a basic Win32 console application that can read but more importantly write to a process's memory. Like it attaches onto a process/.exe

So say I have a pointer and an offset, how would I go about writing data to the pointer/offset?

So like for example the dynamic address is 00A89B开发者_运维百科CA. Pointer is 0x00EBCDB08 and Offset is 0xBCD7

I would like to write an integer value to this address.

How would I go about doing this?
