In C language, Write a function that gets a string containing a positive integer. The function subtracts 1 from that integer and puts the obtained value in the string. void str_subtract_one(char* num); For example: - if before we call str_subtract_one(str) we have str==“1997”, then after return str will be “1996”. - if before we call str_subtract_one(str) we have str==“12345678987650”, then after return str will be “12345678987649”. - if before we call str_subtract_one(str) we have str==“100”, then after return str will be “99”. 1. You may assume that the input is always legal, i.e., the string is a positive integer correctly formatted. 2. Note that the numbers may be larger than the maximum of int or long. That is, you should not try to convert string to int

Write a program that reads in a line consisting of a students name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1.
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]
In C++, write a function isVowel that returns true if a character is a vowel (whether you want to include 'y' as a vowel or not is up to you) and false otherwise. Use this function in a program that asks the user to enter a string of characters and outputs the number of vowels.
in c++: Write a program that prompts the user to input a string. The program then uses the function substr to remove all the vowels from the string. For example, if str = "There", then after removing all the vowels, str = "Thr". After removing all the vowels, output the string. Your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.
Write a C++ program using C-Strings 4. This function returns the index in string s where the substring can first be found. For example if s is “Skyscraper” and substring is “ysc” the function would return 2. It should return -1 if the substring does not appear in the string. int findSubstring(char *s, char substring[]) 5. This function returns true if the argument string is a palindrome. It returns false if it is not. A palindrome is a string that is spelled the same as its reverse. For example “abba” is a palindrome. So is “hannah”, “abc cba”, and “radar”. bool isPalindrome(char *s) Note: do not get confused by white space characters. They should not get any special treatment. “abc ba” is not a palindrome. It is not identical to its reverse. 6) This function should reverse the words in a string. A word can be considered to be any characters, including punctuation, separated by spaces (only spaces, not tabs, \n etc.). So, for example, if s is “The Giants won the Pennant!”…

I need to write a C function that deletes the desired character in a given character string.

n formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of "hello" and " world" is "hello world". Write a function in C language. The function name is conscat_strings that takes a char** as a parameter and return a char* Then in the main function we call the conscat_strings function. Assume the maximum input char number is 100, you do not have to calcualte the number of total chars For example, if I compile the file whcih name is homework1.c by using the gcc on the terminal, I just type gcc homework1.c -o homework.out in mac or gcc homework1.c -o homework.exe in windows. Then I am trying to call the outpout, if I only type ./homework1.out, It should give a hint such as please input at least 3 arguments (inlcude ./homework1.out or ./homework1.exe). if I only type ./homework1.out hello It should give a hint such as please input at least 3 arguments (inlcude ./homework1.out or…
In C++, Write a function that receives a string of characters and return true if the string is in language, otherwise it returns false. You may use following function header (Assume a string is in language if it is read from the left side is the same as it is read from the right side. For example, a-b-d-c is not in the language, a-b-c-a-c-b-a is in language): bool isInLanguage_2(string aString) And I also, want to know if my if statement is incorrect, and if it is how is it incorrect?
In program language C: The problem is to write a program that counts the number of letters, digits, other characters, and total characters from the input. If the user does not provide any additional command-line arguments, count the occurrences from standard input. If there is an additional command-line argument, count the occurrences in the string provided on the command line. It must use two functions: one that calculates the counts from standard input, and another that calculates the counts from a string (in this case you'll want to pass argv[1] to the latter function, if argv[1] exists). In main(), check the number of command line arguments to see which function to call, call the appropriate function to get the counts, and then print out the counts in main(). Each function should require you to return multiple values. The program must use two of the following strategies, one for each of the function implementations: - Create variables in main() that will store the counts and pass…
// Write a function that takes 1 argument, a string. // It returns true if the string is a palindrome (the same forwards and backwards). // It returns false if the string is not a palindrome. const isPalindrome = (string) => { // your code here... // Examples isPalindrome("cat") // returns false //isPalindrome("level") // returns true }
Write a C program that gets a string from the user and counts total number of digits in that string. Assume that the size of your string is 10. Use isdigit() function to check whether the character is digit or not. For example: isdigit(„a‟) returns 0 (false), isdigit(„3‟) returns true(1).Please remember that you need to include <ctype.h> for isdigit() library functionSample Run:Enter your string: cng230There are 3 digits in your string.
Complete the check_character() function which has 2 parameters: A string, and a specified index. The function checks the character at the specified index of the string parameter, and returns a string based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character. Ex: The function calls below with the given arguments will return the following strings: check_character('happy birthday', 2) returns "Character 'p' is a letter"check_character('happy birthday', 5) returns "Character ' ' is a white space"check_character('happy birthday 2 you', 15) returns "Character '2' is a digit"check_character('happy birthday!', 14) returns "Character '!' is unknown" use python please def check_character(word, index): # Type your code here. if __name__ == '__main__': print(check_character('happy birthday', 2)) print(check_character('happy birthday', 5)) print(check_character('happy birthday 2 you', 15))…
