assignment from incompatiable pointer type C -

say want read in list of pages name of max 19 character, e.g. 4 (number of page) name1 name2 name3 name4

i trying use global 2d array store page number , page name, got error saying assignment incompatiable pointer type...

thanks

static int npages; static char** pagename;  int main(void){   scanf(" %d", &npages);    pagename = (char *)malloc(npages*sizeof(char));   for(int i=0; < npages ;i++){     pagename[i] = (char *)malloc(20*sizeof(char));     scanf(" %s", pagename[i]);   }  //free memory here of coz.     return 0; } 

the problem lies right there:

pagename = (char *)malloc(npages*sizeof(char)); 

pagename char **, not char *. should read:

pagename = malloc(npages*sizeof(char*)); // sizeof(char *), , no need cast 

edit: removed cast
