and what do you mean by "all addresses"?

Short answer: no you cannot do this. Even if you can read the memory of another process you have no idea what sort of values are stored there, so the information will be of limited use.

In Windows OS..

For example, User select Chrome.exe and my project will read Chrome.exe addresess in RAM.

0x000000 : 500
0x000001 : 7500
0x000002 : Chrome

Like that, I wanna read RAM addreses..

From what you say it seems that you have some confusion about how a modern OS manage memory.
First of all I suggest you to read this[^] and this[^] to clarify the basics (in an actual OS the memory is virtual and each executable generally is allocated on the same standard virtual address 0x400000).
When you'll have more clear ideas you can start from OpenProcess()[^] function. From this, if you have enough privileges, you can obtain an handle to the process. With this handle you can access the process resources, memory is one of them. Use function ReadProcessMemory()[^] function.
These functions are typically used in debuggers to access debugging process memory, the locations to read to inspect variables are obtained from debug info's using the functions from dbghelp[^] library.

Good luck! ;)

P.S. It should be clear that whichever address you read through ReadProcessMemory() you are reading data at the specified logical address inside the process, not a physical global memory address.
