modify(char a[],char *b)
{
a[0]='a'//gives runtime error why?
b[0]='b'//gives runtime error
}
main()
{
char p[]="hello";
char *x="hello";
x[0]='x';//will give run time error i know why
p[0]='p' //works fine i know why
modify("string","pointer");
}
why un function modify both the assignments give runtiie error are both a
and b acting as pointers to some constant strings
