Incrementing and Decrementing Numbers
Explore how to increment and decrement numbers through pseudocode, C/C++, and assembly instructions like INC and DEC. Understand their representation in GDB disassembly and how memory and registers update during these operations.
Increment and decrement numbers
In pseudocode, incrementing or decrementing the number stored in location (address) a looks very simple:
(a) + 1 -> (a)
(a) – 1 -> (a)
Increment and decrement in C and C++
In C and C++, we can increment and decrement in three different ways:
Increment and decrement in assembly language
In assembly language, we use instructions INC and DEC and write:
We use incl when we ...
