Question

Write an 8086 assembly program to find the factorial of a number. Store 4 different numbers in memory location as input, generate the factorial of each of these numbers and the result(s) is stored in memory at a specified location. Use LOOPS. Execute the Program in 8086 emulator and keep the

screenshot of the result.

Answer 1

To write an assembly program to find the factorial of a number, initialize the input numbers in memory, use a loop to calculate the factorial, and store the result in memory.

Step-by-step explanation:

To write an 8086 assembly program to find the factorial of a number, you can follow these steps:

1. Initialize the input numbers in memory locations.
2. Load the number from memory into a register.
3. Initialize another register with the value 1.
4. Use a loop to calculate the factorial.
5. Inside the loop, multiply the number in the first register by the number in the second register and store the result back in the first register.
6. Decrement the second register by 1.
7. Repeat the loop until the second register becomes zero.
8. Store the final result in memory at a specified location.

For example, if the input number is 5, the factorial can be calculated as:

5! = 5 x 4 x 3 x 2 x 1 = 120.

You can execute the program in an 8086 emulator and store the screenshot of the result.
