write a c++ function that counts the words in a string but does not include numbers for example : if you type in: "too good to be true" ---> you get 5 words in total. "2019" ----> 0 words

In C++ Even if a problem does not directly tell you to use a function, you should aim to do so regardless. 2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

This is for my C++ 2 class, so still a beginner C++ program: Case Manipulator Write a program with three functions: upper, lower, and flip. The upper function should accept a C-string as an argument. It should step through all the characters in the string, converting each to uppercase. The lower function, too, should accept a pointer to a C-string as an argument. It should step through all the characters in the string, converting each to lowercase. Like upper and lower, flip should also accept a C-string. As it steps through the string, it should test each character to determine whether it is upper- or lowercase. If a character is uppercase, it should be converted to lowercase. If a character is lowercase, it should be converted to uppercase. Test the functions by asking for a string in function main, then passing it to them in the following order: flip, lower, and upper.

In C++

In c++, Write a function that returns the greatest common divisor of 2 integers.

C Programming Write a program that reads an integer from the user (keyboard), namely n. Yourprogram should print all positive numbers that are smaller than n and whosedigits sum up to a perfect square number.(An integer is a perfect square if it hasan integer square-root for example 25) You should print the numbers in ascendingorder and print their digits separated by ":" symbol from the least significant digitto the most significant digit on the same line as the number. At the end of eachline you should also print the sum of the digits of the number. Example:If the user enters n : 30, then the output should be as follows:1 1 14 4 49 9 910 0:1 113 3:1 418 8:1 922 2:2 427 7:2 9

C++

in c++ Write a function that takes two strings and returns -1 if the first string is a substring of the second, a 1 if the second string is a substring of the first, or 0 if neither is a substring of the other.
