C Programming: Count total number of vowel or consonant
C String: Exercise-9 with Solution
Write a program in C to count the total number of vowels or consonants in a string.
Sample Solution:
C Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define str_size 100 // Declare the maximum size of the string
int main() {
char str[str_size]; // Declare a character array to store the string
int i, len, vowel, cons; // Declare variables for iteration, string length, vowel count, and consonant count
printf("\n\nCount total number of vowel or consonant :\n"); // Display information about the task
printf("----------------------------------------------\n");
printf("Input the string : ");
fgets(str, sizeof str, stdin); // Read a string from the standard input (keyboard)
vowel = 0; // Initialize vowel count to zero
cons = 0; // Initialize consonant count to zero
len = strlen(str); // Get the length of the input string
// Loop to check each character of the string
for (i = 0; i < len; i++) {
// Check if the character is a vowel (both lowercase and uppercase)
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') {
vowel++; // Increment the vowel count if the character is a vowel
}
// Check if the character is an alphabet (both lowercase and uppercase)
else if ((str[i] >= 'a' && str[i] <= 'z') || (str[i] >= 'A' && str[i] <= 'Z')) {
cons++; // Increment the consonant count if the character is an alphabet but not a vowel
}
}
// Display the total number of vowels and consonants in the string
printf("\nThe total number of vowel in the string is : %d\n", vowel);
printf("The total number of consonant in the string is : %d\n\n", cons);
return 0; // Return 0 to indicate successful execution of the program
}
Sample Output:
Count total number of vowel or consonant : ---------------------------------------------- Input the string : Welcome to w3resource.com The total number of vowel in the string is : 9 The total number of consonant in the string is : 12
