Write a program that uses the function isPalindrome given in Example 6-6 (Palindrome). Test your program on the following strings: madam, abba, 22, 67876, 444244, trymeuemyrt Modify the function isPalindrome of Example 6-6 so that when determining whether a string is a palindrome, cases are ignored, that is, uppercase and lowercase letters are considered the same. The isPalindrome function from Example 6-6 has been included below for your convenience. bool isPalindrome (string str) { int length = str.length(); for (int i = 0; i < length / 2; i++) { if (str[i] != str[length - 1 - i]) { return false; } // if } // for loop return true; }// isPalindrome Your program should print a message indicating if a string is a palindrome: madam is a palindrome

A function that turns an argument to a string (call it “toString(…)”) is a great use of function overloading. In one sentence, why might this be? In one sentence, why should we generally verify the arguments are what we expect when writing a function?

Write a function hasBothCases that takes a a c-string and determines if it contains both the upper and lowercase forms of a letter, returning 11 if both the upper and lowercase form of a letter are part of the string and returning 00 if no such letter exists. For example, hasBothCases should return 11 for the strings "Nine", "Lowell", and "o_O", but should return 00 for "nine", "Massachusetts", and "zyBooks". HINTS: You can make use of either the following: (1) Assume that the <ctype.h> library has already been #included. 2) Upper case letter A starts at 65 and Upper case Z is 90 in ASCII code, while lower case a starts at 97 and z is 122. NOTE: You only need to write the function.  In C programming

Write out a function that prints out all the permutations of a string. For example, abc would give you abc, acb, bac, bca, cab, cba.
