String Utility

Description

This string class is for an assessment for uni. It is a predominantly a wrapper class for cstring functions.

Functions

The class has an assortment of functions. These include:

Length()
CharacterAt()
EqualTo()
Append()
Prepend()
CStr()
ToLower()
ToUpper()
Find()
Replace()
ReadFromConsole()
WriteToConsole()
Wobble()

Length()

The length function returns the length of the string. It gets the string length using the strlen() function, returning the result as a size_t value;

CharacterAt()

The character at function returns a char at the specified index of a string. It supports both const and non const char arrays. The result is returned as a char.

EqualTo()

The equal to function determines whether or not two strings are identical. It does this using the strcmp() function. It returns either true or false.

Append()

The append function concatenates a string at the end of another string. It does this using a combination of strcpy() and strcat(). It returns a reference of itself.

Prepend()

The prepend function concatenates a string at the beginning of another string. It does this using a combination of strcpy() and strcat(). It returns a reference of itself.

CStr()

The cstr function returns a char array for the standary library console out.

ToLower()

The to lower function transforms all characters of the string to lowercase. It does this by looping through each char and using the standard library tolower() function. It returns a reference of itself.

ToUpper()

The to upper function transforms all characters of the string to uppercase. It does this by looping through each char and using the standard library toupper() function. It returns a reference of itself.

Find()

The find function searches and finds the location of a substring within a string. An index can be supplied to search the string from a specific starting point. It returns the location of the substring as a size_t.

Replace()

The replace function replaces all instances of a substring within a string. It returns a reference of itself.

ReadFromConsole()

The read from console function takes in input from the console and saves it as a string. It returns a reference of itself

WriteToConsole()

The write to console function sends output to the console. It returns a reference of itself.

Wobble()

The wobble function alternates letters in sequence between lowercase and uppercase. It returns a reference of itself
