Write a C++ function named dup that makes a copy of a C-string but repeats the C-string. For example, if your C-string contains "bye" the result should be "byebye". Here is what it should do: Dynamically allocate memory (using new) for a new C-string large enough to hold the result C-string. It should be the minimum size necessary to store the result C-string. Don't forget room for a null character! Put the result C-string into the newly allocated memory. It must be a valid, NULL-terminated C-string. Return a pointer to the result string. The function can assume that parameter str points to a valid, NULL-terminated C-string. You can use cstring utility functions like strcpy(), strlen(), etc. if you wish, but you are not required to. You do not need to demonstrate calling this function. Example: dup("Giants")should return a pointer to a newly-allocated, null-terminated C-string: "GiantsGiants" char* dup(char *str)

Write a program in C++ using libraries. Write a function that allows case-insensitive comparison of two strings. The return value should be analogous to that from strcmp: s1 < s2 return something < 0 s1 == s2 return something == 0 s1 > s2 return something > 0 (These return values can be short integers.) Just remember that the comparisons are to be done in a manner that ignores the caseof the letters in the strings! But also note that the strings should not be altered at all. Don't change the two string arguments before or during the call. Don't make copies and change the copies. All of this is terribly wasteful and/or destructive of data. Place your new function in a library (strextra?) and call it something useful (strcmp_ncase?). Write a driver program to test your function.
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)
Write a C++ function named dup that makes a copy of a user input C-string and repeats the C-string. For example, if the user inputs "HelloWorld" then it will say "HelloWorldHelloWorld" Dynamically allocate memory *(using new)* for a new C-string large enough to hold the result C-string. It should be the minimum size necessary to store the result C-string. Don't forget room for a null character! Put the result C-string into the newly allocated memory. It must be a valid, NULL-terminated C-string. Return a pointer to the result string. The function can assume that parameter str points to a valid, NULL-terminated C-string. You can use cstring utility functions like strcpy(), strlen(), etc. if you wish, but you are not required to. Please demonstrate calling this function. Example: dup("Giants")should return a pointer to a newly-allocated, null-terminated C-string: "GiantsGiants" char* dup(char *str)
Write a C function called sorttwo that takes the x and y as parameters and returns both values but with the lowest value first. Call the function and assign the return values to the variables low and high and print both.
Write a program in C programming language that takes two arguments at the command line, both strings. The program checks to see whether or not the second string is a substring of the first (without using the substr -- or any other library -- function). One caveat: any * in the second string can match zero or more characters in the first string, so if the input were abcd and the substring was a*c, then it would count as a substring. Also, include functionality to allow an asterisk to be taken literally if preceded by a \, and a \ is taken literally except when preceding an asterisk.
Write a C++ function that accepts a double typed number and return back the fractional part of the number. For example, if the number is 789.123, the number 0.123 should be returned.
Write a C function delWordN() that takes a string and an integer (n) as parameter, removes from the string the words that are n character long. A word is a group of consecutive alphanumeric characters; words are separated by non-alphanumeric characters. ps: do not take aswers from chegg or from other websites. I can already see them. Write the code yourself. I need different code.
Write a C function strEven() that takes two strings (say s1, s2) as parameters, stores into s2 the even indexed (0th, 2nd, 4th, ...) characters of s1. s2 must be null character terminated. Example: if s1 is "Abcde1234", the function will make s2 as "Ace24" Prototype: void strEven(char s1[], char s2[]);
In the C program, I am trying to create a function that will separate a string by storing the two parts of the string in two variables. The string is randomly selected from the text file and for example if the string is " Halloween - A holiday", I want the string to be separated on the basis of '-'. So the first string would be separated as "Haloween" and the second string would be stored as "-A holiday". The string could have any content but it should split based on the '-' and then the two strings should be stored in the two varaibles
Problem: Write a C++ program that would implement the function called romanToInt which returns the integer equivalent of a given string s in Roman numeral. Roman numerals are represented by seven different symbols each with corresponding values: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500 and M = 1000. Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five, we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used: · I can be placed before V (5) and X (10) to make 4 and 9. · X can be placed before L (50) and C (100) to make 40 and 90. · C can be placed before D (500) and M (1000) to make 400 and 900. ASSUMPTIONS The given string s only contains the characters ('I', 'V', 'X', 'L', 'C', 'D', 'M') It is guaranteed that s is a valid Roman numeral in the…
Write a complete C++ program in one file which takes a double value from the user, cubes it, and prints the result. Your program must use a function which takes a parameter for the value to be cubed and returns the result by reference. The function may not print anything or read anything directly from the user (i.e. no cin/cout in the function). Hint: n cubed is defined as n*n*n.
• Write a function for a double function that will accept either two or three parameters of type double. • If it only receives two parameters, then it will return the average of the two numbers. • If it receives three parameters, then it will return the average of the largest number and the smallest number. • Write a complete C++ program to show the use of this function.
