c - Passing pointer to string, incompatible pointer type -

so i'm sure question answered many times having trouble seeing how fix situation. took snippet of program contains warning-generating code:

#include <stdio.h> #include <stdlib.h>  inputdata(int size, char *storage[size]) {     int iterator = -1;      {         iterator++;         *storage[iterator] = getchar();     } while (*storage[iterator] != '\n' && iterator < size); }  main() {     char name[30];      inputdata(30, name); } 

the warning message:

$ gcc text.c text.c: in function ‘main’: text.c:18:5: warning: passing argument 2 of ‘inputdata’ incompatible pointer type [enabled default] inputdata(30, name); ^ text.c:4:1: note: expected ‘char **’ argument of type ‘char *’ inputdata(int size, char *storage[size])

edit:

ok, managed play around syntax , fixed problem. still wouldn;t mind hearing more knowledgeable why precisely needed. here changed:

#include <stdio.h> #include <stdlib.h>  inputdata(int size, char *storage) // changed point string  {     int iterator = -1;      {         iterator++;         storage[iterator] = getchar(); // changed pointer string     } while (storage[iterator] != '\n'); // same above }  main() {     char name[30];      inputdata(30, name);      printf("%s", name); // added verification } 

array name converted pointer first element when passed function. name converted &name[0] (pointer char type) address of first element of array name. therefore, second parameter of function must of pointer char type.

char *storage[size] equivalent char **storage when declared function parameter. therefore, change char *storage[size] char *storage.
