Answer:

RAX = 333000h (16 bits with preceding zeros removed)

RDX = 20h (also 16 bits with preceding zeros removed)

Explanation:

The "div" opcode in the assembly language source code is used to divide operands. It accepts a divisor ( the denominator) and divides the content of the AX register. The result is saved in the AX register while the remainder (if any) is saved in the DX register. If the DX register holds any data, the data is replaced with the divisor remnant.

The code above divides the content of the RAX register with the divisor variable and saves the result and remainder in the RAX and RDX respectively.

Which would you use to get the number of elements in a dictionary?
Vikentia [17]

The function use to get the number of element in a dictionary is len.

<h3>What is a dictionary?</h3>

Dictionaries are used to store data values in key-value pairs. Dictionary are ordered.

Dictionary in python are express as follows:

my_dict = {"name": "Michael", "age": 28, "school": "Oxford"}

Therefore, the length of the element of the dictionary can be gotten using the len() function.

Hence,

print(len(my_dict)) will give you the length of the element.

Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to
Alik [6]

Answer:

#include<stdio.h>

#include<stdlib.h>

int main(void){

int seedval;

scanf ("%d", &seedval);

srand(seedval);

printf("%d\n", rand()%10);

printf("%d\n", rand()%10);

 return 0;

}

Explanation:

The given code is poorly formatted. So, I picked what is usable from the code to write the following lines of code:

#include<stdio.h>

#include<stdlib.h>

int main(void){

This line declares seedval as integer

int seedval;

This line gets user input for seedval

scanf ("%d", &seedval);

This line calls the srand function to generate random numbers

srand(seedval);

This prints a random number between 0 and 9

printf("%d\n", rand()%10);

This also prints a random number between 0 and 9

printf("%d\n", rand()%10);

 return 0;

}
