Create a simple calculator program. At the beginning program prints out number 0, after which it asks the user for the string in format [operator][number]. The program then prints the intermediate output. The program will stop, when the user inputs string quit. You can make an assumption, that the user inputs only valid strings. The calculator should be able to calculate plus(+) and minus(-) calculations. There is no need to take account of other types of calculations. The example run of the program: 0 Type in a calculation or quit: -30 -30 Type in a calculation or quit: +25 -5 Type in a calculation or quit: quit

This program reads a given set of integers and then prints the number of odd and even integers. It also outputs the number of zeros. Furthermore, it also identifies if the integer is positive or negative. Use looping.
Read string integer value pairs from input until "Done" is read. For each string read: • If the following integer read is less than 40, output the string followed by ": low on stock". • Otherwise, output the string followed by ": well stocked". End each output with a newline. Ex: If the input is Oven 43 Curtain 7 Pillow 1 Done, then the output is: Oven: well stocked Curtain: low on stock Pillow: low on stock 1 #include 2 #include 3 using namespace std; 4 5 int main() { 6 7 8 9 10 } * Your code goes here */ return 0;
Design a program with an algorithm that will take a string from the user and then decide if each character in that string is unique. For example, if you ask the user to enter a string and that user enters the world ‘hello’, the result of the algorithm implementedshould return ‘false’ or ‘not unique’. If the user enters a string such as the word ‘phone’ the program will return ‘true’ or ‘unique’ since every character in the word phone is unique and is not repeated. An example of this program follows: Output should show as : enter a string rizma This string has all the unique characters would u like to continue?(y for yes n for no) y Enter a string waali This string is not unique Your code should work for all strings and essentially all characters, as many examples will be tested.
Please &-. Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization. For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not. Your program should take a string as input and return true if it's a palindrome, and false otherwise. Ik.?
In programming you work with text, sometimes you need to determine if a given string starts with or ends with certain characters. You can use two string methods to solve this problem: .startswith() and .endswith()?
Complete the following program that collects an input word from the keyboard and finds if the word is palindrome. A word is palindrome if the sequence of characters are the same from left-to-right and right-to-left, for example, "dad", "racecar" or "rotor" are all palindrome words because they can be read the same either forward or backward. word = input ("Entera word: ") 1s_palindrome = True i = -1 for if word[j] != word[1]: if not is palindrome: else: i-1 is palindrome = False print ("word is palindrome") jin range(len(word)) i+1 -1 print ("word is not palindrome") len(word) jin word
