Write a C++ Program to Find Substring Of String Without Using Library Functions. Note: Don't use functions. Example: string1= “hello world, this is my world.” string2= “this is” result= “string 2 is a substring of string1” string3= “not” result= “string 3 is not a substring of string1”

Exercise #3: Character Counts Write a c++ program that prompts the user to enter a string, calls the function lowerUpperDigits( ) which takes a string and counts the number of lower, upper, and digit characters in the string. The main program prints the number of found characters.   int lowerUpperDigits(string, int&, int&); Sample input / output:

Using C++ write this code Write a function called isValidNote that accepts a string and returns true if that string is a valid note expressed in SPN and false otherwise. See the explanation above for clarity on what is and is not considered valid SPN. Function Specifications: Name: isValidNote() Parameters (Your function should accept these parameters IN THIS ORDER): note (string): The string to be checked Return Value: True or false (bool) The function should return true if the string is a valid note in SPN and false otherwise. The function should not print anything. The function should be case-sensitive, e.g. B0 is valid SPN but b0 is not. Hint: Any note expressed in valid SPN will be exactly 2 characters long. --- Examples --- Sample function call Expected return value isValidNote("y") False isValidNote("D4") True isValidNote("d4") False isValidNote("E72") False isValidNote("I love coding") False Your file should be named isValidNote.cpp and should also…
