5.18 LAB: Count characters - functions 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. Ex: If the input is: n Monday the output is: 1 Ex: If the input is: z Today is Monday the output is: Ex: If the input is: n It's a sunny day the output is: Case matters. n is different than N. Ex: If the input is: n Nobody the output is: Your program must define and call the following function that returns the number of times the input character appears in the input string. int CountCharacters(char userChar, string userString)

C++ Given code is  #pragma once#include <iostream>#include "ourvector.h"using namespace std; ourvector<int> intersect(ourvector<int> &v1, ourvector<int> &v2) {    // TO DO: write this function    return {};}

/* Programming concept: structures Program should: be a C program, define a structure to store the year, month, day, and high temperature. write a function get_data that has a parameter that is a pointer to a struct and reads from the user into the struct pointed to by the parameter. write a function print_data that takes the struct pointer as a parameter and prints the data. in main, declare a struct, call the get_data function, call the print_data function. */ #include <stdio.h> int main(int argc, char *argv[]) {   return 0;}

C++ Write a void function that has two parameters: a value parameter called num that receives a floating point number from the calling function and a floating point reference parameter called result. The functions should do this calculation: 25.0 * num + 37 and store the answer in result. Do not do any read or write operations in the function.
