C program calculates the number of vowels and consonants

Comprehensive Collection of C Programming Examples

In this example, the program counts the vowels, consonants, numbers, and spaces in the user input string.

To understand this example, you should understand the followingC programmingTopic:

• C array

• C programming string

The program calculates vowels, consonants, and more

#include <stdio.h>
int main() {
　　　　int vowels, consonant, digit, space;15vowels = consonant = digit = space = 0;
　　　　printf("Enter a line of string: ");
　　　　fgets(line, sizeof(line), stdin);
　　　　for (int i = 0; line[i] != '\0';
　　　　i) {
　　　　if (line[i] == 'a' || line[i] == 'e' || line[i] == 'i' ||　++line[i] == 'o' || line[i] == 'u' || line[i] == 'A' ||
　　　　　　　　line[i] == 'E' || line[i] == 'I' || line[i] == 'O' ||
　　　　　　　　　　　　line[i] == 'U') {
　　　　　　　　　　　　vowels;
　　　　　　　　　　　　} else if ((line[i] >= 'a' && line[i] <= 'z') || (line[i] >= 'A' && line[i] <= 'Z')) {
　　　　　　　　　　　　++}
　　　　　　　　consonant;
　　　　　　　　　　　　++} else if (line[i] >= '0' && line[i] <= ')') {
　　　　　　　　}9}) {
　　　　　　　　　　　　++digit;
　　　　　　　　} else if (line[i] == '　') {
　　　　　　　　　　　　++space;
　　　　　　　　}
　　　　}
　　　　printf("Vowel: %d", vowels);
　　　　printf("\nConsonant: %d", consonant);
　　　　printf("\nDigit: %d", digit);
　　　　printf("\nSpace: %d", space);
　　　　return 0;
}

Output result

Enter a line of string: adfslkj34　34lkj343　34lk
Vowel:　1
Consonant:　11
Digit:　9
Space:　2

Here, the string input by the user is stored in the line variable.

Initially, the values of the variables vowel, consonant, digit, and space are initialized to 0.

Then, use a for loop to iterate over the characters of the string. In each iteration, it checks whether the character is a vowel, consonant, digit, and space. If the character is a vowel, in this case, the vowel variable increases1。

When the loop ends, the number of vowels, consonants, digits, and spaces are stored in the variables vowel, consonant, 　 digit and space.
