Functions

Question 1

puts( )

Answer 1

The puts() function in C is used to output a string to the standard output (typically the console) followed by a newline character (\n). It is defined in the <stdio.h> header file.</stdio.h>

Question 2

rand()

Answer 2

The rand() function in C is used to generate pseudo-random integers. It is defined in the <stdlib.h> header file. This returns a pseudo-random integer in the range 0 to RAND_MAX, where RAND_MAX is a constant defined in <stdlib.h> (usually 32767). Without seeding, the sequence of numbers is the same every time the program is run.</stdlib.h></stdlib.h>

Question 3

srand()

Answer 3

Use srand() to seed the random number generator witha. starting value (e.g., srand(time(Null));).

For numbers in a specific range, use:
int random_number = rand() % (upper - lower +1) + lower;
