Help

Can anyone help me?:(
So i have to convert (or something like that) a c++ program into assembly.
The program used will be visual studio.

I would like a tutorial for idiots (like me☻ ) to explain where to put that breakpoint and why...
How to "translate" cout;cin;i++, and stuff like this in assembly code

Something like this
C++ stuff:
Y = 2
Z = 4
...
X = (Y + Z) / 2

ASM stuff
PUSH CX
PUSH BX
...
POP BX
MOV AX, BX
POP BX
ADD AX, BX
MOV CX, 02h
DIV AX, DX

i once implemented a sophisticated smalltalk-style oop in assembler using only the EAX register when I was 12
