Need some help

[Mr.wut]

for homework at school i need to make program which will calculate and decide if number set by user is prime number.

i thought about doing it with an it sentence but it wolud have to go something like this: 

if (number%everything betwen number and 1==0) {

cout << "number isn't prime"

}else {

number is prime

}

and my actual question is if there exist a command that can automaticaly devides the number with evrey number betwen? 

i need to do it in c++

 

pls help.

tnx

No, but you could use a for loop. Programming isn't just about finding premade functions that do exactly what you need.
