Dada una string, cuente el número total de consonantes en ella. Una consonante es un carácter del alfabeto inglés que no es una vocal (a, e, i, o y u). Ejemplos de constantes son b, c, d, f, g, ..
Ejemplos:
C++
// Iterative CPP program to count total number
// of consonants
#include <iostream>
using namespace std;
// Function to check for consonant
bool isConsonant(char ch)
{
// To handle lower case
ch = toupper(ch);
return !(ch == 'A' || ch == 'E' ||
ch == 'I' || ch == 'O' ||
ch == 'U') && ch >= 65 && ch <= 90;
}
int totalConsonants(string str)
{
int count = 0;
for (int i = 0; i < str.length(); i++)
// To check is character is Consonant
if (isConsonant(str[i]))
++count;
return count;
}
// Driver code
int main()
{
string str = "abc de";
cout << totalConsonants(str);
return 0;
}
Java
// Iterative Java program
// to count total number
// of consonants
import java.io.*;
class GFG {
// Function to check for consonant
static boolean isConsonant(char ch)
{
// To handle lower case
ch = Character.toUpperCase(ch);
return !(ch == 'A' || ch == 'E' ||
ch == 'I' || ch == 'O' ||
ch == 'U') && ch >= 65 && ch <= 90;
}
static int totalConsonants(String str)
{
int count = 0;
for (int i = 0; i < str.length(); i++)
// To check is character is Consonant
if (isConsonant(str.charAt(i)))
++count;
return count;
}
// Driver code
public static void main(String args[])
{
String str = "abc de";
System.out.println( totalConsonants(str));
}
}
