C++ program to count number of vowels, consonants in a string

C++ program to count number of vowels, consonants in a string

In this article, we will discuss the concept of C++ program to count number of vowels and consonants in a string

In this post, we are going to learn how to write a program to  count Total number of vowels and consonants in a string in C++ language

Code to count number Vowels and consonants  in given string

Code to count number of vowels and consonants using for loop

In this code, we are going to learn how to write a program to count total number of vowels and consonants present in the given string using if else statements in C++ language

Program 1

#include <iostream>
#include <conio.h>
#include <stdio.h>
using namespace std;

int main()
{
    char str[100];//Char array declaration
    int i;//declare variable i
    int vowelCount=0,consonantCount=0;
//declare and initialize counter variable
    cout<<"Please enter a string\n";//ask input from user
    gets(str);//reading the input
    for(i=0; str[i]!='\0'; i++){

  if(str[i] == 'a'|| str[i] == 'e'|| str[i] == 'i'|| str[i] == 'o'|| str[i] == 'u'
  ||str[i] == 'A'|| str[i] == 'E'|| str[i] == 'I'|| str[i] == 'O'|| str[i] == 'U'){
    vowelCount++;//count vowels
  }
  else if((str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){
    consonantCount++;//count consonant
  }
}
cout<<"The number of vowels: "<<vowelCount;
cout<<"\nThe number of consonant: "<<consonantCount;


getch();
    return 0;
}

When the above code is executed, it produces the following result

Please enter a string
Vowels
The number of vowels: 2
The number of consonants: 4

 

Code to count number of vowels and consonants using while loop

In this code, we are going to learn how to count total number of vowels and consonants present in the given string using while loop in C++ language

Program 2

#include <iostream>
#include <conio.h>
#include <stdio.h>
using namespace std;

int main()
{
    char str[100];//Char array declaration
    int i;//declare variable i
    int vowelCount=0,consonantCount=0;
//declare and initialize counter variable
    cout<<"Please enter a string\n";//ask input from user
    gets(str);//reading the input
    i=0;
    while(str[i]!='\0'){

  if(str[i] == 'a'|| str[i] == 'e'|| str[i] == 'i'|| str[i] == 'o'|| str[i] == 'u'
  ||str[i] == 'A'|| str[i] == 'E'|| str[i] == 'I'|| str[i] == 'O'|| str[i] == 'U'){
    vowelCount++;//count vowels
  }
  else if((str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){
    consonantCount++;//count consonant
  }
   i++;
}
cout<<"The number of vowels: "<<vowelCount;
cout<<"\nThe number of consonant: "<<consonantCount;


getch();
    return 0;
}

When the above code is executed, it produces the following result

Please enter a string
Vowel count
The number of vowels: 4
The number of consonants: 6

 

Code to count number of vowels and consonants using do-while loop

In this code, we are going to learn how to count total number of vowels and consonants present in the given string using do-while loop in C++ language

Program 3

#include <iostream>
#include <conio.h>
#include <stdio.h>
using namespace std;

int main()
{
    char str[100];//Char array declaration
    int i;//declare variable i
    int vowelCount=0,consonantCount=0;
//declare and initialize counter variable
    cout<<"Please enter a string\n";//ask input from user
    gets(str);//reading the input
    i=0;
    do{

  if(str[i] == 'a'|| str[i] == 'e'|| str[i] == 'i'|| str[i] == 'o'|| str[i] == 'u'
  ||str[i] == 'A'|| str[i] == 'E'|| str[i] == 'I'|| str[i] == 'O'|| str[i] == 'U'){
    vowelCount++;//count vowels
  }
  else if((str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){
    consonantCount++;//count consonant
  }
   i++;
}while(str[i]!='\0');
cout<<"The number of vowels: "<<vowelCount;
cout<<"\nThe number of consonant: "<<consonantCount;


getch();
    return 0;
}

When the above code is executed, it produces the following result

Please enter a string
Consonant count
The number of vowels: 5
The number of consonants: 9
