What is div mod is a question many of you ask when learning Pascal programming. Failure to distinguish these two math operations will cause you to fail the exam, leading to depression and not learning the next math.

In today’s article hocmay.vn will explain in detail what div mod is and guide you how to do div mod exercise successfully in high school. You can also refer to the article: 25 must-read books on business management.

What is div mode?

What is Div Math?

Div is the main field, used for all groups.

Explanation: A div B = C. Where: A is the divisor, B is the divisor and C is the divisor between A and B.

For example: 30 divided by 7 = 4

What are mods?

Unlike divs, mods are divided by remainder and used for all groups.

The word mod is the same as the word div (mentioned in the previous section).

For example: 35 mods 6 = 5

What are the attributes and methods that distinguish mod divs?

Divisibility has mod = 0

Mod value is always less than divisor because if equal then this is not divisor with remainder, no mod works.

The value of the Div is always greater than the value of the value, because if equal then this is division, no mods work.

To differentiate between div mods, let’s take another example like this:

32 divided by 6 = 5; 32 mods 6=2. Because 32 divided by 6 gives 5 remainder 2.

Use div . mode

Div mod is used to separate the digits of a number. Specifically: Take for example the number 123456. First take 123456 mod 10 = 6, that is, the number 6 has been separated from the original number. Then take 123456 div 10=12345 as next step. Using 12345 already in the previous step to calculate 12345 mod 10 = 5 is to separate the number 5 from the original number.

Continue this process until all numbers are separated from the original number.

Apply div mod to a specific Pascal problem

After you understand what div mod is, let’s read how to apply div mod to a specific Pascal problem.

Data to file: Dem _CS.inp

Export to file: Dem_CS.out

It has the number n

Example: 12456

– Line 1: write the number of digits

– Line 2: Enter the number of digits

Problem definition

if n = 0 then set the counter variable to 1 and otherwise set the variable to 0. This is the code that handles the special problem n = 0, if this happens the program will not perform the operation After and at the same time it will confirm the number has 1 digit and the number of digits and 0. Depending on the algorithm, there are often obvious events that we have to program to handle separately.

While loop: this function repeats the function

Divide each number of digits (right to left) – using mod
after division, remove the number – use Div

Instructions for using the mod to calculate the sum, difference, product, and quotient of any 2 numbers

Specifically, the code that uses the div mod function to calculate the sum, difference, product, and quotient of two numbers is as follows:

use crt;

var a,b,tg,i,tong:integer;

crystal(x, y: integer): integer;

begin

tg:=xy;

if tg=0 then Tinh:=y other Tinh:=tinh(y,tg);

COMPLETE;

BEGIN

clrscr;

write(‘Talking:’); readln(a);

write(‘Text ab:’); read (b);

group:=1;

for me: = 2 to do abs(a+b).

if (abs(a+b) mod i = 0) then tong:=tong+i;

writeln(‘Two so: ‘,a+b);

writeln(‘Understand 2 as:’, ab);

writeln(‘Mark 2 as: ‘,a*b);

writeln(‘Two like: ‘,a/b:0:4);

writeln(‘UCLN 2 so: ‘,tinh(a,b));

writeln(‘One of ‘,a+b,’ is: ‘,tong);

read

COMPLETE.

Match numeric values using div and mod

Here is how to apply div mod to the problem of calculating the sum of the digits of any number, follow along to strengthen your knowledge in this section.

BEGIN

clrscr;

write(‘Pap 1 so three parts:’); readln(a);

tong:= mod 10;

a:= div 10;

tong:=tong+a mod 10;

a:= div 10;

tong:=tong+a mod 10;

writeln(‘Cong elephant: ‘,tong);

Use mod to check number, odd number, prime number, positive number

This is how you can use the mod to see what numbers are: even, odd, prime,…

use crt;

var n,i:integer;ok:boolean;

BEGIN

clrscr;

write(‘Press n:’); readln(n);

if n mod 2=0 then writeln(‘So ‘,n,’ la so chan’)

other writeln(‘So ‘,n,’ staggered’);

if n<2 write('So ',n,' does not compare to')

other

begin

good:= true;

for me: = 2 for trunc(sqrt(n)) to do

if n mod i=0 then ok:=false;

if ok then writeln(‘So ‘,n,’ is so nguyen to’)

else writeln(‘So ‘,n,’ not good for’);

COMPLETE;
