Textbook Question
Chapter 8.1, Problem 4STE
Suppose the function strlen (which returns the length of its string argument) was not already defined for you. Give a function definition for strlen. Note that strlen has only one argument, which is a C string. Do not add additional arguments; they are not needed.

Write a c++ function that takes a string as parameter and returns the number of words in that string.
Write a function that replaces a substring with a new string.
Example:
>>> replace('The quick brown fox jumps over the lazy dog', 'quick', 'slow')
The slow brown fox jumps over the lazy dog
The first parameter is the string, second is the substring to be replaced and the third is the string to replace the substring.
If there are more than one occurrence of a substring, replace it all.

- Write a function in C++ to take a string as parameter and also returns a string that is the palindrome of the given string. string createPalin(string s){ //Write your code here //Return a string that is palindrome of s }arrow_forwardWrite a C++ function named getLowerAlphabets that takes a C-string argument and returns a C-stringmade up of the lower alphabet characters of the argument. If none of the characters of the argument is alower alphabet then you must still return a C-string which is obviously empty C-string; that is a C-stringwith only the null character.arrow_forwardWrite a function in C progarmming language that gets a string str, changes all lower case letters to * (asterisk), and all upper case letters to $ (dollar sign). All other characters remain unchanged. The function returns the total number of letters modified. int hide_letters(char* str); For example: - If str is "12ab0", then the function changes it to "12**0", and returns 2. - If str is "aBCDe*", then the function changes it to "*$$$**", and returns 5. - If str is "0123&***", then the function keeps the string as is, and returns 0. - An empty string is also a string.arrow_forward
- Write a function in C++ that takes a string as a parameter and returns the sum of ASCII value of all lowercase alphabets in the string. The function returns 0 if no lowercase alphabet it is present in the string. Test the function taking a sample string inside the main function.arrow_forward(C++) Question: Write a function string middle(string str)that returns a string containing the middle character in str if the length of str is odd, or the two middle characters if the length is even. For example, middle("middle") returns "dd". I'm not getting the correct output. What am I doing incorrectly?arrow_forwardWrite 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 programmingarrow_forward
- Write a C++ function named louder which accepts a pointer to a C-string as its argument. It should do 3 things: - change any period (.) in the C-string to an exclamation point (!) - change any lower case letter in the C-string to the corresponding upper case letter - return the number of characters which were changed You may assume that parameter str points to a valid, null-terminated C-string containing only alphabetic characters, spaces and periods. You do not need to demonstrate calling this function. Example: if str points to an array containing "Giants win." the function should change the array so that it contains "GIANTS WIN!", and should return 9. You must use this function signature: int louder(char *str)arrow_forwardWrite code for a C++ function that takes input a string and returns it's length without using any library function. Do fast please.arrow_forwardDo Programming Exercise 4 from Chapter 5 using a function acronym(phrase)that returns an acronym for a phrase supplied as a string.arrow_forward
- In C language, implement the function that gets a string str, changes all digits of str to 0 (zero), and returns the number of digits in the string. int digits_to_zero (char* str); For example: If str is "12ab0", then the function should change it to "00ab0", and return 3. If str is "abcde", then the function should keep it as is, and return 0. [Hint 1: you can check if a char is a digit using its numerical value. The numerical values of the digits are consecutive. For example, we have '3' + 2 =='5'] [Hint 2: you can also use the function isdigit (char c) implemented in the library <ctype.h> https://www.programiz.com/c-programming/library-function/ctype.h/isdigit]arrow_forwardWrite a function str_replace that takes three strings, str1, str2 and str3; and replaces the first occurence (if any) of str2 in str1 with str3, and returns the newly formed string. For example, str_replace("Nuclear Energy Engineering", "Nuclear Energy", "Mechanical") returns "Mechanical Engineering"arrow_forwardWrite a program in C to find vowels in a string s1 and concatente those vowels with string s2 in uppercase only.
