yo guys , i wrote this program and compiled in turboc, but it gets error"declaration syntax error" .
whats the problem over here ? help me out thanks .Code:#include <stdio.h> int main() int isprime(int n) { if(n<2) return 0; for(int i=2;i<=n/2;i++) { if((n%i)==0) return 0; return 1; } }
main() is supposed to be a function in its own right - for example, that might call isprime().
Prefixing the definition of isprime() with "int main()" doesn't magically turned isprime() into the main function of the program.
If you don't understand what I said, open any basic textbook on C, and look up how to implement functions. Don't rely on guesswork like you clearly have.
Well it seems that even the horrible Turbo-C knows you shouldn't define a function inside another function. You need to move the isPrime() definition to before main, and it really wouldn't hurt if you came into this century by obtaining a more modern compiler.

well i do have devc and bcw , but they dont work properly on my pc . if you know anything then suggest me where i can code my c programs .(well i dont have enough space on my computer for visual c)
thanks both jim and grumpy
visual C++ is not recommended for compiling C code, because it doesn't implement any recent version of the C standard. I'd recommend code::blocks or eclipse.Originally Posted by qozmyox
What can this strange device be?
When I touch it, it gives forth a sound
It's got wires that vibrate and give music
What can this thing be that I found?
Logic is not right. Will return "is prime" before all divisors are checked.
