Eax, EBX, ECx, EDX, ESI, EDI, EBP, ESP, etc. are the names of General registers on the CPU in x86 assembly language, and are 32-bit registers. These registers can be viewed as variables in C language. For example:Add eax,-2;// It can be considered that a value such as-2 is added to the variable eax. These 32-bit registers have multiple purposes, but each of them has "expertise" and has its own special features. EaxIt is an accumulator, which is t
