Question

I am trying to create a makefile for the following program in Unix. The C++ program I am trying to run is presented here. I was wondering if you could help me create a makefile for the following C++ file in Unix and show screenshots of the process? I am doing this all in blue on putty and not in Ubuntu, so i don't have the luxury of viewing the files on my computer, or I don't know how to anyway

Program:

//main.cpp

#include <iostream>
using namespace std;

int main() {
    string s;
    char ch;
    int vowels = 0, consonants = 0, digits = 0, specialCharacters = 0;

    getline(cin, s);

    for (int i = 0; i < s.length(); i++) {
        ch = s[i];
        if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')) {
            if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' || ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U') {
                vowels += 1;
            }
            else {
                consonants += 1;
            }
        }
        else if (ch >= '0' && ch <= '9') {
            digits += 1;
        }
        else {
            specialCharacters += 1;
        }
    }

    cout << "Vowels: " << vowels << endl;
    cout << "Consonants: " << consonants << endl;
    cout << "Digits: " << digits << endl;
    cout << "Special characters: " << specialCharacters << endl;

    return 0;
}

1. Copy the programs in the specific files.

2. Make sure that all files are in the same location.

3. Now open terminal and compile the files as follows

c++   main.cpp hello.cpp program.cpp -o hello

./hello

main.cpp

#include <iostream>
using namespace std;

#include "functions.h"

int main(){
   Hello_World();
   cout << endl;
   My_Program();
   return 0;
}

hello.cpp

#include <iostream>

using namespace std;

#include "functions.h"

void Hello_World(){
   cout << "Hello World!";
}

program.cpp

#include "functions.h"
#include <iostream>
using namespace std;

void My_Program(){

    string s;
    char ch;
    int vowels = 0, consonants = 0, digits = 0, specialCharacters = 0;

    getline(cin, s);

    for (int i = 0; i < s.length(); i++) {
        ch = s[i];
        if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')) {
            if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' || ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U') {
                vowels += 1;
            }
            else {
                consonants += 1;
            }
        }
        else if (ch >= '0' && ch <= '9') {
            digits += 1;
        }
        else {
            specialCharacters += 1;
        }
    }

    cout << "Vowels: " << vowels << endl;
    cout << "Consonants: " << consonants << endl;
    cout << "Digits: " << digits << endl;
    cout << "Special characters: " << specialCharacters << endl;

}

functions.h

void Hello_World();
void My_Program();
