Exit mistake

[Karajic]

Hi everyone!

Can you help me with my assignment
I'm truing to write a function which will give the message and exit the program, but when I'm trying to compile the system always gives me a mistake that exit(1)isn't declared. What to do? does anybody have an idea?

void error(char *msg)
{
perror(msg);
exit(1);// this is the place where the error occurs
}
