In this article, we will discuss the concept of C program to count vowels and consonants in a string
In this post, we are going to learn how to count the vowels and consonants in the given string in C programming language
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 <stdio.h> #include <stdlib.h> int main() { char str[100];//declara a char array int i,vowCount=0,consCount=0;//declare counter variables printf("Enter a string for count vowel and consonant\n"); gets(str); for(i=0; str[i]; 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' ){ vowCount++; } else if((str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){ consCount++; } } printf("The number of vowels: %d \n",vowCount); printf("The number of consonant: %d \n",consCount); getch(); return 0; }
When the above code is executed, it produces the following result
Enter a string for count vowel and consonant Vowels The number of vowels: 2 The number of vowels: 4
Approach
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 2
#include <stdio.h> #include <stdlib.h> int main() { char str[100];//declare a character array int i,vowCount=0,consCount=0;//declare counter variables printf("Enter a string for count vowel and consonant\n"); gets(str);//store the string input from the user i=0; while(str[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' ){ vowCount++; } else if((str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){ consCount++; } i++; } printf("The number of vowels: %d \n",vowCount); printf("The number of consonant: %d \n",consCount); getch(); return 0; }
When the above code is executed, it produces the following result
Enter a string for count vowel and consonant Vowel and consonant The number of vowels: 6 The number of vowels: 11
Approach
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 3
#include <stdio.h> #include <stdlib.h> int main() { char str[100]; int i,vowCount=0,consCount=0; printf("Enter a string for count vowel and consonant\n"); gets(str); 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' ){ vowCount++; } else if((str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z' )){ consCount++; } i++; }while(str[i]); printf("The number of vowels: %d \n",vowCount); printf("The number of consonant: %d \n",consCount); getch(); return 0; }
When the above code is executed, it produces the following result
Enter a string for count vowel and consonant Alphabet letters The number of vowels: 5 The number of vowels: 10
