所以我正在尝试计算元音、辅音和特殊字符的数量。我可以使用元音和特殊部分,但不能使用辅音。这是代码;

#include <iostream>
using namespace std;

void characterType(string);

int main()
{
string input = "Testing a sentence.";
characterType(input);
}

void characterType(string input)
{
int vowel, consonant, special = 0;

for (int i = 0; i < input.length(); i++)
{
char character = input[i];

if((character >= 'a' && character <= 'z') ||(character >= 'A' && character <= 'Z'))
{
character = tolower(character);

if (character == 'a' || character == 'e' || character == 'i' || character == 'o' || character == 'u')
{
vowel++;
}
else
{
consonant++;
}
}
else
{
special++;
}
}
cout<< "Vowels: " << vowel << endl;
cout<< "Consonant: " << consonant << endl;
cout<< "Special Character: " << special << endl;
}

这是输出; enter image description here

我似乎无法弄清楚,有人知道吗?

最佳答案

定义

int vowel, consonant, special = 0;

仅将special初始化为0。另外两个变量未初始化,并且将具有不确定值。

您需要显式初始化所有想要具有特定初始值的变量:

int vowel = 0, consonant = 0, special = 0;

这就是为什么许多人建议每个语句只定义一个变量:

int vowel = 0;
int consonant = 0;
int special = 0;
