Flag is not clear

#1

what is the meaning of flag in this case and how can we use it in case of checking prime number till N

hey @AK072672
Flag is just a name of variable if a number is prime we can set the variable flag value as 1 and check if flag==1 then just print this number else if flag==0 then skip as it is not prime

flag is just a name of variable you can keep it anything it can be int a,int b ,int var etc anything for generalisation we keep its name as flag
