[singharchi]

hello please solve this prob (LValue required)

void main()
{

int a=0;
char *ptr[10]={" kanitkar","balagurushami","morishmano"};
char str[20];
clrscr();

cout<<"enter name to search\n";
cin>>str;

for(a=0;a<3;a++)
{

if(!strcmp(str, *ptr[a]))

{

cout<<"book is found"<<endl;
break;
}
ptr++;
}
if(a==3)
cout<<"book not found";

On which line of your code do you get the error?

[weaknessforcats]

There is no LVALUE error in this code.

The only error is using a char instead of a char* as a strcmp argument.

Maybe you could explain your situation in a little more detail.

LValue required on line 15th

[Banfa]

And by line 15 did you actually mean line 22

ptr++;

?

ptr is an array you can't perform arithmetic operations on an array.

It is not even clear what you intend as you increment the array control variable else where (a++ in the loop).


You whole program invokes undefined behaviour as you return void from main. main ALWAYS returns int.
