____ is a prototype of a function that returns no value.

A. void funcA();
B. funcA();
C. int funcA();
D. null funcA();

Placing the appropriate #include statement at the top of the program ensures proper access to the library functions whose prototypes are contained in the header file.

The rand() function produces a series of random numbers in the range 0 < rand() < RAND_MAX, where the constant RAND_MAX is a compiler-dependent symbolic constant that is defined in the stdlib.h header file.
