I thought I could return an array like I do in Java, but I think there is no way to declare a char function in C.

CodePudding user response：

No. You return an array via a pointer (possible embedded in a struct). The array is either dynamically allocated in the function, or passed into the function as an argument and then returned again:

char *f() {
  char *s = malloc(42);
  ...
  return s;
}

char *f2(char *s) {
  ...
  return s;
}
