Answer to Question #44194 in C for Vijayasurya

Question

In my Data Structures text book there is mergesort program.
In that the function prototype is mergesort( int *,int,int) whereas the function header is
mergesort(int a[], int lb, int ub) , please explain int * in the prototype it should actually be int a[] !!

Answer 1

Dear Vijayasurya,
Actually int * and int[] is the same thing.
int[] is the pointer to the first array element, where int* is the pointer to variable.
So basically they're the same (as array element is actually a variable).
Hope that helps.
