What is the difference between array of character and string?

Question

What's the basic difference between hardware and software solutions for critical section problem? Why are they called hardware or software solution?

Answer 1

In C language, string is collection of characters followed by NULL character, while array of character is collection of characters only without NULL character at last. For example:
char array[ ] = { 'a', 'b', 'c' }; /* Example of array of characters */
char string = "abc"; /* Example of string */

There is a typo in char string = "abc"; I think you intended to have
char *string = "abc"
the diff between a char *string and char arr[] is that the base of (any) array is a const pointer whereas, for the pointer, its not (unless you make the pointer const)

Even though, both string and array variables point to the base of the array.

ex:
char *string = "abc";
string ++;
printf("%s", string);
//would print bc because, string was pointing to base of the array abc which had a.
char aray[] = {'a','b','c'};
array ++; // this is an invalid operation and compiler would throw an error as attempting to modify an lvalue because base of this (and any array) is a const pointer.

Thanks to correct me. I missed  * before string variable.
