Is there a way to return an array in C from a user defined function?

Question

Please help me with c program which takes less memory and time to sort a unsorted array of 1000 chars, its order should not be more then O(N) and memory should be most least as possible. Use bit fields and share the program?

Answer 1

well, an array is basically a pointer to an area in memory where a chain of variables of the same data type are stored. so, to answer your question, yes. you can. just return a pointer.

example:
int* functionThatReturnsIntArray(){

//allocating memory for the array dinamically (or you could just receive it as a parameter in your function)
int* array = (int) malloc (sizeof(int) * numberOfElementsInTheArray);

//process the array here

return array;
}
