Write a C++ program to input a string from the user and convert all vowels in the string to uppercase. You have to also print the number of vowels that are converted to uppercase. If any vowel is already uppercase then it should not be counted in the answer. Input: afhEtkuoA Output: AfhEtkUOA, 3

I need help writing a C++ code. I need help writing a function that accepts a C-string as an argument and returns the number of words contained in the string. Let's say the string argument is "Howdy Partner" the function should return the number 2. Demonstrate the function in a program that asks the user to input a string and then pass it to the function. The number of words in the string should be displayed on the screen.

Read a 2-character string from input into variable inputString. Declare a Boolean variable isValid and assign isValid with true if inputString contains a lowercase letter. Otherwise, assign isValid with false. Ex: If the input is y-, then isValid is assigned with true, so the output is: Valid string Ex: If the input is 21, then isValid is assigned with false, so the output is: Invalid string Note: Use getline(cin, inputString) to read the entire line from input into inputString. #include <iostream>#include <string>#include <cctype>using namespace std; int main() {   string inputString;    /* Your code goes here */      if (isValid) {      cout << "Valid string" << endl;   }   else {      cout << "Invalid string" << endl;   }    return 0;}

USing basic C++ code pls!!!

Use C++ language

In C++ Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. n is different than N. Ex: If the input is: n Nobody the output is: 0 n's The program must define and call the following function that takes the input string and character as parameters, and returns the number of times the input character appears in the input string.int CalcNumCharacters(string userString, char userChar)

Write a function that accepts a pointer to an integer array and the array's size as arguments. The function should allocate a new array, copy the items from the original array to the new one in reverse order, and then deallocate the original array.
