Please explain Python Code # 2) Write a procedure that takes a string and returns that string ROT13'ed. def rot13(word): encryptedword = "" for c in word: if c >= 'a' and c <= 'm': # a..m encryptedword += chr((ord(c)+13)) elif c >= 'n' and c <= 'z': # n..z encryptedword += chr((ord(c)-13)) else: # don't encrypt letters encryptedword += c return encryptedword #print(rconvertup("example")) print(rot13("example!")) print(rot13(rot13("example!")))

3. Word Counter Write a function that accepts a pointer to a C-string as an argument and returns the number of words contained in the string. For instance, if the string argument is "Four score and seven years ago" the function should return the number 6. Demonstrate the function in a program that asks the user to input a string then passes it to the fune- tion. The number of words in the string should be displayed on the screen. Optional Exercise: Write an overloaded version of this function that accepts a string clás object as its argument.

C++ :  Write a function that inserts a given string in the middle of a second string. If the second string has an oddnumber of characters, the program first repeats the last character before inserting. Write a program to test your function.

C++ is my answer correct ? Write a function to convert a given string : Answer: #include <iostream> #include <string> using namespace std;   void toUpper(string &str) {         for (int i = 0; i < str.length(); i++)     {         str[i] = toupper(str[i]);     } }   void toLower(string &str) {        for (int i = 0; i < str.length(); i++)     {         str[i] = tolower(str[i]);     } }   int main() {     string str = "khaled";     toUpper(str);     cout << str << endl;       str = "MOHAMMED";     toLower(str);     cout << str << endl;       return 0; }   Write a function to calculate the sum of the even number from 1 - 100. Answer: #include <iostream> using namespace std;   int sumEven() {        int sum = 0;           for (int i = 1; i <= 100; i++) {                 if (i % 2 == 0) {                         sum += i;         }     }     return sum; } int main() {     cout << sumEven() << endl;     return 0; }

String to integer ATOI (requires use of INT_MAX and INT_MIN): Implement the myAtoi(string s) function, which converts a string to a 32-bit signed integer (similar to C/C++'s atoi function). The algorithm for myAtoi(string s) is as follows: Read in and ignore any leading whitespace. Check if the next character (if not already at the end of the string) is '-' or '+'. Read this character in if it is either. This determines if the final result is negative or positive respectively. Assume the result is positive if neither is present. Read in next the characters until the next non-digit character or the end of the input is reached. The rest of the string is ignored. Convert these digits into an integer (i.e. "123" -> 123, "0032" -> 32). If no digits were read, then the integer is 0. Change the sign as necessary (from step 2). If the integer is out of the 32-bit signed integer range [-231, 231 - 1], then clamp the integer so that it remains in the range. Specifically, integers less…
