Chapter 12, Problem 19RQE
Write a function whose prototype is
char lastChar(const char *str)
that takes a nonempty C-string as parameter and returns the last character in the string. For example, the call lastChar("abc") will return the character c.

in c++
write three overloaded functions called stringOperation that take in the following formal parameters list:
Function 1: takes as input a string, ONE character, and an integer n, and returns true if the string contains that character EXACTLY an n number of times.
Function 2: takes as input a string and TWO alphabatical characters c1 and c2, and returns true if all the string characters fall in the range between the two passed characters (exclusive) (You must make sure to order the characters first if c2 < c1 ).
Function 3: takes as input a string and THREE alphabatical characters c1, c2 and c3. The function reorders the characters in asecnding order, such that c1 holds the smallest character and c3 holds the largest character.
The function returns true if the string characters that fall between c1 and c2 (exclusive) is less than the string characters that fall between c2 and c3 (exclusive).
Do not write and submit the main subroutine, or any include statments, these are…
In C language, Write a function that gets a string containing a positive integer. The function subtracts 1 fromthat integer and puts the obtained value in the string.
void str_subtract_one(char* num);
For example:- if before we call str_subtract_one(str) we have str==“1997”, then after return str will be “1996”.- if before we call str_subtract_one(str) we have str==“12345678987650”, then after return str will be “12345678987649”.- if before we call str_subtract_one(str) we have str==“100”, then after return str will be “99”.
1. You may assume that the input is always legal, i.e., the string is a positive integer correctly formatted.2. Note that the numbers may be larger than the maximum of int or long. That is, you should not try to convert string to int
This is for my C++ 2 class, so still a beginner C++ program:
Case Manipulator Write a program with three functions: upper, lower, and flip. The upper function should accept a C-string as an argument. It should step through all the characters in the string, converting each to uppercase. The lower function, too, should accept a pointer to a C-string as an argument. It should step through all the characters in the string, converting each to lowercase. Like upper and lower, flip should also accept a C-string. As it steps through the string, it should test each character to determine whether it is upper- or lowercase. If a character is uppercase, it should be converted to lowercase. If a character is lowercase, it should be converted to uppercase. Test the functions by asking for a string in function main, then passing it to them in the following order: flip, lower, and upper.
