Consider the following definitions and statements: char ch = '\0'; char *chp; chp = &ch; The character variable ch is stored in a memory cell on the right. What is the value of chp? Consider the following definitions: int x; int *px; int a [10]; int *pa; Assume that px is assigned to point to x and pa is assigned to point to a [0]. Match the variables in column A (on the left) with the equivalent variables in column B (on the right)
