In the "eval_expr.cpp" file, you will implement the conversion algorithm in the following function. * @brief Convert an infix expression to an equivalent postfix expression @param infix_expr The input expression in the infix format. * @return the converted postfix expression. If the input infix expression is invalid, return an emp */ String convertInfixToPostfix (string infix_expr) Then implement a function to evaluate infix expressions by using the convertInfixToPostfix and evalPostfixExpr functions. bool evalInfixExpr(string infix_expr, float& result);

- There are three types of edits that can be performed on strings: insert a character,remove a character, or replace a character. Given two strings, write a function to check if they areone edit (or zero edits) away.EXAMPLEpale, ple -> truepales, pale -> truepale, bale -> truepale, bae -> falseIn this assignment, your program will read up to 80 characters from the keyboard and store thecharacters in a string (think about the string / buffer size you should declare). The characters couldbe letters, numbers, punctuation, and spaces. You CANNOT use %s and scanf or fscanf(stdin) to do this task because it is not safe; do not use fgets either for the purpose ofthis exercise. Instead, you may use scanf with %c or the getchar() function to read character-bycharacter and then save them to the string. The string should not include the new-line character.After reading the characters into the array, print it on the screen (with a new line character) byusing %s with the printf function. Then your program will call a function named reverseStringthat will take the string as its argument. The function will reverse the string (in place) and returna pointer to the reversed string back to the calling function. In your main program, print thereversed string with a new line.You may NOT use a…This exercise is to write a Decimal to Hex function using BYTE operations. You can use a List, Dictionary or Tuple for your Hex_Map as shown below, but it's not necessary to use one. It is necessary to use Byte operations to convert the decimal to hex. The bitwise operations are also available as __dunders__. Write a function to convert a integer to hexidecimal. Do not use the Python hex function (i.e. hexnumber = hex(number)) to convert the number, instead write your own unique version (i.e. MYHEX: hexnumber = MYHEX(number)). Your function should not use any Python functions like hex, dec, oct, bin or any other Python functions or modules. Functions, like Python ORD, can be used to convert a string to a integer. The input number range is 0 to 1024. def MYHEX(number): hex_map = {10: 'A', 11: 'B', 12: 'C', 13: 'D', 14: 'E', 15: 'F'} result = '' while number: digit = number % 16 if digit > 9: result = hex_map[digit] + result else:…

For instance, the function strncpy (s,t,n) copies up to n characters from t to s.

- The program will ask the user for their name and employee ID. The ID will be a five-digit number. This will be done in a single function, AskNameId, with bool return, where the name and id are passed as pointers. Read both variables as strings with a getline and convert the id to an int using atoi. Check that the id is not 0. If it is, cout a message to the user for entering an invalid id. Check if the name is an empty string. If it is, cout a message to the user for entering an invalid name. Return a bool, true if name and id are both valid and false if either one is not valid.You will write a function that can be used to decrypt Dan’s encrypted text. You will be given an open file that contains an encrypted passage from one of the books, and the name of a file containing a wordlist of English words. You need to discover the shift value to use (0-25) in order to decrypt the text. A correct shift value is one that leads to the maximum number of words being found in the English list of words. To find the words in the encrypted text, you must call split(). For a given shift value, convert all letters to lowercase, then try to find each word in the English wordlist. Do not remove any punctuation or symbols from the word: for example, if the word is hello!, then that is the exact string, including exclamation mark, that you should try to find in the English wordlist. Your function should return a string where all letters are in lowercase, and all other characters (newlines, spaces, punctuation, etc.) are retained. Input In each test case, we will call your…Create a function get-random the parameters -count and the set -maximum and - minimum are mutually exclusive in POWERSHELL as follows: a)Write your own version of get-random that accepts all 3 of -count -min and -max as switches. It should call the standard version to produce results. Your version does not have to handle a list of values. b) The value of count should default to 1 and should have an alias of nItems. c) Write a loop to produce the requested # of items. d) Test your functions with float and integer values. e) Use the group-object cmdlet to prove that your function will generate repeats.
