Assembly Language Lab report even or odd

Experiment No:
Experiment Name: Flow control if else (An assembly program that can take as input and print as an output find the number is even or odd).
Objectives: To be able to print the number is even or odd.
Apparatus: MICROPROCESSOR EMULATOR 8086, Computer etc
Introduction: Conditions in assembly language control the execution of loops and branches. The program evaluates the conditional instruction and executes certain instructions based on the evaluation. The CMP and JMP instructions implement conditional instructions.

Compare and jump instructions

The CMP instruction takes two operands and subtracts one from the other, then sets O, S, Z, A, P, and C flags accordingly. CMP discards the result of subtraction and leaves the operands unaffected. The following syntax is used for CMP instructions: CMP DST SRC
The JMP instruction transfers the program control to a new set of instructions indicated by the label in the instruction. The following syntax is used for JMP instructions: JMP label

Procedure:
1. Create: open emu8086 write a program after that save the program with .asm extension.
2. Compile: Emulator
3. Execute: Run
