consts.h
Declaration of constants used by the modules.

Preprocessor file used for including library for modules.

isHexDigit
bool isHexDigit(char character)
Checks if a char is a hexadecimal digit (not case sensitive).
Definition utility.c:101

containsFrom
bool containsFrom(const char *string, char character, int startPosition)
Checks if there is an occoruncy of the passed char from the passed position in the passed string.
Definition utility.c:63

decimalDigitToInt
int decimalDigitToInt(char digit)
If is a decimal digit, converts it to int; Otherwise returns ASCII integer representation of the pass...
Definition utility.c:105

count
int count(const char *string, char character, int startPosition)
Counts the number of occoruncies in the string, from a passed position, of the passed char.
Definition utility.c:50

evalutateBase
int evalutateBase(char *number)
Evalutates the base of the number (by finding the biggest digit up to hexadecimal digit F) and return...
Definition utility.c:123

isDecimalDigit
bool isDecimalDigit(char character)
Checks if a char is a decimal digit.
Definition utility.c:97

offsetFromNext
int offsetFromNext(const char *string, char character, int startPosition)
Counts the offset in the string between the position and the next occoruncy of the passed char.
Definition utility.c:38

nDigits
int nDigits(int number)
Evalutates the number of digits of a number. The time complexity of this function is constant (O(1)).
Definition utility.c:138

substring
char * substring(const char *string, int startPosition, int length)
Copies a substring (heap-allocated) from the passed string. If fails when allocating memory for the s...

int hexDigitToInt(char digit)
If is a hexadecimal digit (not case sensitive), converts it to int; Otherwise returns ASCII integer r...

containsSubstringFrom
bool containsSubstringFrom(const char *string, const char *subString, int startPosition)
Checks if there is an occoruncy of the passed substring from the passed position in the passed string...
