Answer / avinash
In this question ,two wrong thins ----
1.this is an array of char pointer so use
strcy(text[no.],"Hello World");
2.
we are copying a string without allocating memory to pointer . This is bug code .
correct solution :----
char *string()
{
char *text[20];
text[0]=malloc(20*sizeof (char));
strcpy(text,"Hello world");
return text;
}

as for as i know , there is only one error..... you have
declared text as array of pointers and not as character data
array..... so this text can only accept addresses.... :)
char *text[20] means you are going to store 20 addresses in
this array..... When you store addresses using arrays , the
that is called array of pointers....
if u declare : char text[20] , this will work correctly..
thank u
