Compilers convert C code into Instructions

HEAP

Whenever you use malloc or calloc or global or static variable we use the memory of heap

Registers

Registers are special memory containers present in CPU.

There are general purpose registers (eax,ebx,ecx,edx,esi,edi) & Reserved registers (ebp,esp,eip)

The Stack

push & pop

Stack grows downward

Whenever functions are called code & variables are stored in stack as stack frame

ebp -> base pointer

esp -> stack pointer

(esp - ebp ) denotes the stack frame for one function

Instructions

1. mov r1,r2;
