Which of the following is NOT an example of data?

A function that modifies an array by using pointer arithmetic such as ++ptr to process every value should have a parameter that is:

a. A nonconstant pointer to nonconstant data. b. A nonconstant pointer to constant data. c. A constant pointer to nonconstant data. d. A constant pointer to constant data.

What method does the function use to refer to array elements?

void reverse( char *string1, const char *string2 ) { int stringsize = sizeof( string1 )/sizeof( char ); *( string1 + stringsize –1 ) = '\0'; string1 = string1 + stringsize – 2; for ( ; *string2 != '\0'; string1--, string2++ ) *string1 = *string2; } a. Array subscript notation. b. Pointer/offset notation where the pointer is actually the name of the array. c. Pointer subscript notation. d. Pointer/offset notation.
