how to go through the pointers

hello!
I am not able to follow how should i like the same thing in pointers:

int a[10], b= 1, c; // initialization
a[++b]=c; // increment

If I want to write the same thing in pointer, then what would it be like

int *a, b =1, c;
a = (int*) calloc(10, sizeof(int));
//how would the third line be written ??????
