Write a c++ program to read a text file and count number of vowels.

#include<fstream.h>
#include<iostream.h>
#include<ctype.h>
#include<conio.h>

void  main()
{
    char fname[30],lname[30];
int c=0;
char ch;

clrscr();
   
cout<<"Enter First Name = ";
cin>>fname;
 
cout<<"Enter Last Name = ";
cin>>lname;
   

ofstream ostud("stud.asa", ios::out);
ostud<<fname<<"\n"<<lname;

ostud.close();

ifstream istud("stud.asa",ios::in);

while(istud>>ch)
{
ch=tolower(ch);

if(ch=='a'||ch=='e'||ch=='i'||ch=='o'||ch=='u')
{
c++;
}

}


cout<<"Number of vowels in file are = "<<c;

istud.close();
getch();

}

/*
OUTPUT:-

Enter First Name = ARJUN
Enter Last Name = SINGH
Number of vowels in file are = 3
