Question

Can someone please edit my current code to accept a user input for the text file name in lieu of how it currently will read data1.txt. Also if the user enters a data file that isn't ready to be used, cout a statement "cout << "Could not open file " << userInputforData.txt << endl;

Another condition that I need to add is if there is a special character anywhere in the word it cannot be an acceptable variable name.

could you also add a count function that ive already declared for the total of valid variable names.

Below is my current c++ code:

#include <iostream>
#include <string>
#include <fstream>
#include <cctype>
using namespace std;
void printReport(string userText, int vowels, int consonents, int specialCharacters, bool isValid);
bool isVowel(char c);
//void getCount(string userText, int& vowels, int& consonents, int& numbers, int& specialCharacters);
bool isValid(char t);
int main()
{
    ifstream inFile("data1.txt");
    string s;
    char ch;
    int vowels = 0, consonents = 0, specialCharacters = 0, numbers = 0;
    while(inFile >> s) {
        vowels = consonents = specialCharacters = numbers = 0;
        for (int i = 0; i < static_cast<int>(s.length()); i++) {
            ch = s[i];
            if(i==0) {
                if ((ch >= 'a' && ch <= 'z'))
                    printReport(s, vowels, consonents, specialCharacters, true);
                else{
                    printReport(s, vowels, consonents, specialCharacters, false);
                }
            }
            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 {
                    consonents += 1;
                }
            } else if (!(ch >= '0' && ch <= '9')) {
                specialCharacters += 1;
            } else if (ch >= '0' && ch <= '9') {
                numbers += 1;
            }
        }
      //  cout << s <<  " " <<vowels << " " << consonents << endl;

    }
   // printReport(s, vowels, consonents, specialCharacters);
    isVowel(ch);
    inFile.close();
    return 0;
}
/*void getCount(string userText, int& vowels, int& consonents, int& numbers, int& specialCharacters);{

}*/
void printReport(string s, int vowels, int consonents, int specialCharacters, bool isValid) {
    if (isValid) {
        cout << "The variable name - " << s <<  " - is valid." << endl;
    }
    else {
        cout << "The variable name - " << s << " - is invalid." << endl;
    }
}
bool isVowel(char ch){
    if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' || ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U'){
        return true;
    }else{
        return false;
    }
}
