Write program in c++

Assume letters A, E, I, O, and U as the vowels. Write a program that reads strings from a text file, one line at a time, using a while-loop. You do the following operations within each loop:

Read the one line from the input file and store it in a string;

Count the number of vowels and consonants (using either while-loop or for-loop) in the string The while-loop will terminate when the end-of-file is reached. After the loop is finished, display the total number of vowels and consonants in the text file. [A text file, named “ass4_Q1_input.txt”, is provided as your testing input file.]

Explanation / Answer

#include<iostream>
#include<fstream>

using namespace std;

// function to check whether a character is vowel or not
bool isVowel(char c){
   if(c=='a'||c=='A'||c=='e'||c=='E'||c=='i'||c=='I'||c=='o'||c=='O'||c=='u'||c=='U') {
return true;
}
else {
return false;
}
}
// function to check whether a character is consonant or not
bool isConsonant(char c){
   if(!isVowel(c) && ((c>='a' && c<='z')||(c>='A' && c<='Z')))
       return true;
   else
       return false;
}

int main(){
  
   ifstream infile("ass4_Q1_input.txt");
   int vowelCount=0, consCount=0;
   string line;
   while (getline(infile, line)) // reading line by line
   {
       unsigned int i=0;
       while(i < line.size()){ // traversing current line
           if(isVowel(line.at(i)))
               vowelCount++;
           else if(isConsonant(line.at(i)))
               consCount++;
           i++;
       }
   }
  
   cout<<"Total number of vowel: "<<vowelCount<<endl;
   cout<<"Total number of consonaant : "<<consCount<<endl;
   return 0;
}

Sample Run:

Content of ass4_Q1_input.txt:

Read the one line from the input file and store it in a string;
Count the number of vowels and consonants (using either while-loop or for-loop)
in the string The while-loop will terminate when the end-of-file is reached.
After the loop is finished, display the total

Output:

Total number of vowel: 82
Total number of consonaant : 129
