Fatemeh What if your loop and if block doesn't execute then your function will not return anything which should return because return type is int so you should return 0 after end of for loop

Fatemeh Your program will always return true because of (i < n && c == 0) and if(c == 0)

Also the logic is not true. You cannot find prime number in this way. To find a prime number, we have to check if that number is perfectly divisible by any integers between 2 and the root of our number. If it is perfectly divisible even by 1 number , it is not prime. https://code.sololearn.com/cNQa8jPCopGv/?ref=app
