Program for count vowel and consonant of a string in C++ using ASCII value

In this article, we will discuss the concept of Program to count vowel and consonant of a string in C++ using ASCII value

In this post, we are going to learn how to count the vowels and consonants in the given string using ASCII value in C++ programming language

Code to count vowel and consonant of a string

Code to count the vowels and consonants using for loop

The program allows the user to enter a string  thereafter It counts the vowels and consonants of the given string using for loop in C++ language

Program 1

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

int main()
{
    char str[100];//character array declaration
    int i;
    int vowelCount=0,consonantCount=0;//counter variable declaration

    cout<<"Please enter a string\n";
    gets(str);//store the entered string
    for(i=0; str[i]!='\0'; i++){

    if(str[i] == 97|| str[i] == 101|| str[i] == 105|| str[i] == 111|| str[i] == 117
    ||str[i] == 65|| str[i] == 69|| str[i] == 73|| str[i] == 79|| str[i] == 85 ){
        vowelCount++;//vowel counter incremented by 1
    }
    else if((str[i] >= 97 && str[i] <= 122 || str[i] >= 65 && str[i] <= 90 )){
        consonantCount++;//consonant counter incremented by 1
    }
}
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

 

Approach

1. Declare a character Array as char str[100];
2. Declare and initialize two integer counter variable as int vowCount=0 and consCount=0;
3. The user asked to enter a string to count vowels and consonants
4. A for-loop is used to count total vowels and consonants of the given string
5. It is initialized as i=0, and checks the test-expression and executes the loop until the given condition becomes true
6. Use an if statement to test vowel, if the test expression is true,  vowCount becomes vowCount + 1(vowCount=vowCount+1)
7. When the if-condition is false, control moves to else-if and checks the test expression of else-if
8. If the test-expression of else if is true,  consCount becomes consCount + 1(consCount =consCount +1)
9. If the test expression of else if is false, control skips from the loop
10. Finally, the program displays the number of vowels and consonants of the given string.

Code to count the vowels and consonants using while loop

The program allows the user to enter a string  thereafter It counts the vowels and consonants of the given string using while loop in C++ language

Program 1

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

int main()
{
    char str[100];
    int i;
    int vowelCount=0,consonantCount=0;

    cout<<"Please enter a string\n";
    gets(str);
    i=0;
    while(str[i]!='\0'){

    if(str[i] == 97|| str[i] == 101|| str[i] == 105|| str[i] == 111|| str[i] == 117
    ||str[i] == 65|| str[i] == 69|| str[i] == 73|| str[i] == 79|| str[i] == 85 ){
        vowelCount++;
    }
    else if((str[i] >= 97 && str[i] <= 122 || str[i] >= 65 && str[i] <= 90 )){
        consonantCount++;
    }
     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

consonant count

The number of vowels:: 5

The number of consonants: 9

 

Approach

1. Declare a character Array as char str[100];
2. Declare and initialize two integer counter variable as int vowCount=0 and consCount=0;
3. The user asked to enter a string to count vowels and consonants
4. A while-loop is used to count total vowels and consonants of the given string
5. It is initialized as i=0, and checks the test-expression and executes the loop until the given condition becomes true
6. Use an if statement to test vowel, if the test expression is true, vowCount becomes vowCount + 1(vowCount=vowCount+1)
7. When the if-condition is false, control moves to else if and checks the test expression of else-if
8. If the test-expression of else-if is true, consCount becomes consCount + 1(consCount =consCount +1)
9. i is incremented by 1
10. If the test expression of else if is false, control skips from the loop
11. Finally, the program displays the number of vowels and consonants of the given string.

 

Code to count the vowels and consonants using do-while loop

The program allows the user to enter a string  thereafter It counts the vowels and consonants of the given string using do-while loop 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;
    int vowelCount=0,consonantCount=0;
//counter variable declaration

    cout<<"Please enter a string\n";
    gets(str);//store the entered string from user
    i=0;
    do{

    if(str[i] == 97|| str[i] == 101|| str[i] == 105|| str[i] == 111|| str[i] == 117
    ||str[i] == 65|| str[i] == 69|| str[i] == 73|| str[i] == 79|| str[i] == 85 ){
        vowelCount++;//vowel counter incremented by 1
    }
    else if((str[i] >= 97 && str[i] <= 122 || str[i] >= 65 && str[i] <= 90 )){
        consonantCount++;//consonant counter incremented by 1
    }
     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
vowels and consonants
The number of vowels:: 5
The number of consonants: 9

 

Approach

1. Declare a character Array as char str[100];
2. Declare and initialize two integer counter variable as int vowCount=0 and consCount=0;
3. The user asked to enter a string to count vowels and consonants

5. It is initialized as i=0, and checks the test-expression and executes the loop until the given condition becomes true
6. Use an if statement to test vowel, if the test expression is true,  vowCount becomes vowCount + 1(vowCount=vowCount+1)
7. When the if-condition is false, control moves to else if and checks the test expression of else-if
8. If the test-expression of else-if is true,  consCount becomes consCount + 1(consCount =consCount +1)
9. If the test expression of else if is false, control skips from the loop
10. Finally, the program displays the number of vowels and consonants of the given string.
