Certainly! Here is a simple program in x86 assembly language to calculate the factorial of a given number:

section .data
    number db 5
    result dw 1

section .text
    global _start

_start:
    mov cx, 1
    mov ax, 1

calculate_factorial:
    cmp cx, byte[number]
    jg end_calculation

    imul ax, cx
    inc cx
    jmp calculate_factorial

end_calculation:
    mov word[result], ax

    ; Add code here to display or store the result

    ; Exit the program
    mov eax, 1
    xor ebx, ebx
    int 0x80

This program initializes the number to calculate the factorial of (in this case, 5) and then iterates through a loop to calculate the factorial using the imul instruction. The result is stored in the result variable. You would need to add code to display or store the result as needed.

What is a program in c to calculate factorial of number?

First of all we will define what factorial is and how to it is calculated.Factional is non negative integer. Notation would be n! It is calculated by multiplying all integers from 1 to n;For example:5! = 1 x 2 x 3 x 4 x 5 = 120.Note: 0! = 1Small C program that illustrates how factorial might be counted:#include int factorial(int num);int main() {int num;printf("Enter number: ");scanf("%d", &num);printf("Factorial: %d\n", factorial(num));return 0;}int factorial(int num) {if (num == 0) {return 1;}return num * factorial(num - 1);}Testing:Enter number: 5Factorial: 120Enter number: 0Factorial: 1

There isn't a reason to write a complete program to do this; in any assembly language just shift the value 1 bit to the left to double it.

How many zeros are possible factorial 10 to the power factorial 10?

To calculate the number of zeros in a factorial number, we need to determine the number of factors of 5 in the factorial. In this case, we are looking at 10 to the power of 10 factorial. The number of factors of 5 in 10! is 2 (from 5 and 10). Therefore, the number of zeros in 10 to the power of 10 factorial would be 2.
