Cpp code: count vowel,consonant,digit,special character and space

In this article, we will discuss the concept of the Cpp code: count vowel, consonant, digit, special character and space

In this post, we are going to learn how to count the total number of Vowels, consonants, digits, special character and Space of the given string in C++ programming language

C++ program to count Vowels, consonants, digits, special characters and space of a string

Count vowels, consonants, digits, special characters and space using for loop

The program allows the user to enter a String and then it counts and display the total number of vowels, consonants, digits, special characters and Spaces of the given string using for loop in C++ programing language

program 1

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

int main()
{
   char str[100];//declare and initialize char array
   int i; int digits=0,spaces=0,spe_Char=0;//display and initialize variables
   int vCount=0,cCount=0;
   cout<<"Please enter the string \n";
   gets(str);//stored the string entered by user
   for(i=0; str[i] != '\0'; i++){
        if(str[i] == 'a'|| str[i] == 'e'|| str[i] == 'i'|| str[i] == 'o'|| str[i] == 'u' || //check vowels
           str[i] == 'A'|| str[i] == 'E'|| str[i] == 'I'|| str[i] == 'O'|| str[i] == 'U' ){
               vCount++;
   } else if(
             (str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){ // check consonants
   cCount++;
             }
             else if(str[i]>='0' && str[i]<='9') // check digits
    {
        digits++;
    }
    else if(str[i]==' '){ // check spaces
        spaces++;
    }
    else{
        spe_Char++;
    }
}
cout<<"\nTotal Vowels: "<<vCount; //display total number of vowels
cout<<"\nTotal consonants: "<<cCount; //display total number of consonants
cout<<"\nTotal digits: "<<digits; //display total number of digits
cout<<"\nTotal white space : "<<spaces; //display total number of spaces
cout<<"\nTotal special characters: "<<spe_Char; //display total number of special characters
getch();
    return 0;
}

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

Please enter the string

Total vowels: 7
Total consonants: 9
Total digits: 5
Total white space: 2
Total white special characters: 2

Count vowels, consonants, digits, special characters and space using while loop

The program allows the user to enter a String and then it counts and display the total number of vowels, consonants, digits, special character and Space of the given string using while loop in C++ programing language

Program 2

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

int main()
{
   char str[100];//declare and initialize char array
   int i; int digits=0,spaces=0,spe_Char=0;//display and initialize variables
   int vCount=0,cCount=0;
   cout<<"Please enter the string \n";
   gets(str);//stored the string entered by user
   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' ){
               vCount++;
   } else if(
             (str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){
   cCount++;
             }
             else if(str[i]>='0' && str[i]<='9')
    {
        digits++;
    }
    else if(str[i]==' '){
        spaces++;
    }
    else{
        spe_Char++;
    }
     i++;
}
cout<<"\nTotal Vowels: "<<vCount;
cout<<"\nTotal consonants: "<<cCount;
cout<<"\nTotal digits: "<<digits;
cout<<"\nTotal white space : "<<spaces;
cout<<"\nTotal special characters: "<<spe_Char;
getch();
    return 0;
}

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

Please enter the string

Total vowels: 12
Total consonants: 20
Total digits: 1
Total white space: 2
Total white special characters: 3

Count vowels, consonants, digits, special characters and space using do-while loop

Program 3

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

int main()
{
   char str[100];//declare and initialize char array
   int i; int digits=0,spaces=0,spe_Char=0;//display and initialize variables
   int vCount=0,cCount=0;
   cout<<"Please enter the string \n";
   gets(str);//stored the string entered by user
   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' ){
               vCount++;
   } else if(
             (str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){
   cCount++;
             }
             else if(str[i]>='0' && str[i]<='9')
    {
        digits++;
    }
    else if(str[i]==' '){
        spaces++;
    }
    else{
        spe_Char++;
    }
     i++;
}while(str[i] != '\0');
cout<<"\nTotal Vowels: "<<vCount;
cout<<"\nTotal consonants: "<<cCount;
cout<<"\nTotal digits: "<<digits;
cout<<"\nTotal white space : "<<spaces;
cout<<"\nTotal special characters: "<<spe_Char;
getch();
    return 0;
}

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

Please enter the string

Total vowels: 9
Total consonants: 14
Total digits: 1
Total white space: 2
Total white special characters: 3

Approaches

Declare a char array as char str[100];
Declare and initialize integer variables as vCount=0,cCount=0,digits=0,spaces=0,spe_Char=0;
The user asked to enter a string
The given string is stored in the variable str;
A loop(for, while and do-while) is used to count every total of the vowel, consonant, digit.space and special characters in the given string
It is initialized as i=0, checks the condition wether (str[i] != ‘\0’) and executes the loop until the given condition becomes true
Use an if condition to test vowels, when the test expression is true, The vCount becomes vCount+ 1( vCount= vCount +1);
When it is false, control moves to the else-if (second condition) and evaluates the test-expression of else-if. if it is true The cCount becomes cCount+1(cCount=cCount+1);
When it is false, control moves to the next else-if part(third condition) and evaluates the test-expression of else-if. if it is true The digits becomes digits+1(digits=digits+1);
When it is false, control moves to the next else-if part(fourth condition) and evaluates the test-expression of else-if. if it is true The space becomes space+1(space=space+1);
When it is false, control moves to the else part and executes the else part statements. the special becomes special+1
Finally, the program displays the total number of the vowels, consonants, digits, Special character and Space of the given string
