int getchar(void); Reads a character from stdin.
char *gets(char *s); Reads a line from stdin.
int putchar(int c); Writes a character to stdout.
int puts(const char *s); Writes a line to stdout.
div_t Structure type that is the type of the value returned by the div function.
ldiv_t Structure type that is the type of the value returned by the ldiv function.
size_t Unsigned integral type of the result of the sizeof operator.
wchar_t Integral type whose range of values can represent distinct codes for all members
of the largest extended character set specified among the supported locales.
EDOM Expands to distinct nonzero integral constant expressions.
ERANGE Expands to distinct nonzero integral constant expressions.
EXIT_SUCCESS Expands to integral expression which indicates successful termination status.
EXIT_FAILURE
Expands to integral expression which indicates unsuccessful termination
status.
HUGE_VAL Expands to a positive double expression, not necessarily represented as a
float.
NULL Expands to a null pointer constant.
RAND_MAX Expands to an integral constant expression, the value of which is the
