What is the difference between Char a[ ]=”string” and char *a=”String”..

Answer / prasant nayak

differences are as follows
1.
Char a[]="string"; //invalid, coz--its not 'Char' but
its 'char' , i.e its syntaticaly incorrect

char *a="string";//it correct

2.
char a[]="string";

above 'a' is an array of characters , where we can change
the string, its not a constant.
i.e we can do a[3] = 'Z';

char *a = "string";

above 'a' is a string constant where we can't change the
string i.e we can't do a[3] = 'Z';

Answer / sushant mahajan

Ohk... dudes I think that 'C' in Char a[] is a typo. The only difference I can see is this:

char *a="string";
printf("%d", sizeof(a));
/*will print 2 or 4, whatever is the memory assigned to a pointer*/

char a[]="string";
printf("%d", sizeof(a));
/*will print 7 - 1 byte for each character+1 byte for the '\0' */

So basically its a memory thing :D

Answer / anshul

I guess the main difference for which interviewer was looking for it that name of the array is constant pointer and character pointer is not. So, if
char a1[]="string";
char *a2="string";

a2=a1;//Compiles and works perfectly
a1=a2;//Error caught at compile time

This is a famous example and is available in many C books.

Answer / ratish

c/c++ is case sensitive language. so Char is invalid data type. hence char *a="String" is correct answer.

Answer / vincy

the syntax for a character variable is wrong if we use a
pointer variable as given above that is char*a="string". so
i think the first one is right.we know that the pointer
variable points to the value in the particular address, then
it should not the "string" but "&string".
