hey guys i have a problem running this code of vowel counting my code is only reading the first line only can sme1 please help...thanx in advance

 #include <iostream>
#include <fstream>
#include <string>

using namespace std;

void CalculateVowel(string word)
{
    //string word;
    ifstream infile("input.txt");
    int  numofA =0;
    int  numofE =0;
    int  numofI =0;
    int  numofO =0;
    int  numofU =0;
    int numofConsonants=0;
    int numofSpaces=0;
    ofstream outfile("output.txt");
    int i=0;


    while((!infile.eof())||(i<word.size()))
    {
        getline(infile,word);

        if((word.at(i) =='a')||(word.at(i) =='A'))
        {
            numofA++;
        }
        else if((word.at(i) =='e')||(word.at(i) =='E'))
        {
            numofE++;
        }
        else  if((word.at(i) =='i')||(word.at(i)=='I'))
        {
            numofI++;
        }
        else if((word.at(i) =='o')||(word.at(i) =='O'))
        {
            numofO++;
        }
        else if((word.at(i) =='u')||(word.at(i)=='U'))
        {
            numofU++;
        }
        else if(word.at(i) =='  ')
        {
            numofSpaces--;
        }
        else
        {
            numofConsonants++;
        }
    } 
    outfile<<"a "<<numofA<<endl;
    outfile<<"e "<<numofE<<endl;
    outfile<<"i "<<numofI<<endl;
    outfile<<"o "<<numofO<<endl;
    outfile<<"u "<<numofU<<endl;
    outfile<<"consonants  "<<numofConsonants<<endl;
}
int main()
{
    string word;
   CalculateVowel(word);
return 0;
}

you are not incrementing i

EDIT :
btw, i think the word parameter in Calculate() function has no purpose other creating unnecessary temporary variables and using more memory.

It would be better if you will remove word from the function parameter and just declare it below the function.

void CalculateVowel( )
{
    string word;
    
     // ...
}
