C++ Program to Check for Prime or Composite Number with User Input ( Explained in Detail )

In this video you will learn to write a C++ Program to Check whether the Number Entered by the User is Prime or Composite Number.
A Prime Number is a natural number greater than 1 which is completely divisible only by 1 and itself. if a natural number is not a prime number then it is called as a Composite Number.
1 is neither prime nor composite

Thank you 😊

How to make a flowchart of this?

Thank you so much

Pleasure

[@sohailahmed8144]

Thank u for this
We need more tutorials for c++

[@LearningLad]

sure :)

[@rajadas9716]

why the code showing 9 is prime?

[@smsofficial4809]

You are an absolute legend

Please make a series of videos on data structure using c++

[@LearningLad]

i will plan one :)

Hello .. Can anyone tell me why this code( without bool ) is not working ...
int main() {
int num;
int divisor;
coutnum;
if(num < 1){
cout

I think you can't use break twice.

Thank you bhai 🙏

[@LearningLad]

Most welcome

You make this easy problem in the complex way

[@StaticBlaster]

Sounds like you own a rooster. lol.

using namespace std ;
#include
int main ()
{
float number, i, flag=0;
cout number ;
if (number

Tell me my mistake

[@GoldPoptart]

@@sourabhkumar8603 I believe it is the bracketing system on the IFs and ELSE IFs

[@onurolce]

if we enter '2' in input then number variable will be 2 and for loop won't work. This is a bug.

[@LearningLad]

the for loop will not execute because the loop condition fails in the beginning.
this is not a bug.
program produces proper result

[@poojaj2905]

Super clear explanation...

[@LearningLad]

Glad you liked it

[@9841554468]

what if user enters decimal point value ? what would be the code for not allowing float or double ?

[@carosworldofficial]

Had to write it... Finally: FIIRRRSSSSSTTTTTT!!!
Nice tutoruals, btw!

[@AliAlRabeeiaaa41]

Line 15 the condition should be
divisor

[@R7amos]

that the other way to do that problem ..
Its your choice what method you prefer
