C++ 程序打印从 a 到 z 的字母

编写一个 C++ 程序，通过示例打印从 a 到 z 的字母。此处，for 循环 (for(char lwalpCh = ‘a’; lwalpCh <= ‘z’; lwalpCh++) ) 迭代从 a 到 z 的字符。在循环内，cout << lwalpCh << ” “; 语句打印从 a 到 z 的字符。

#include<iostream>
using namespace std;

int main()
{
	cout << "\n---List of Lowercase Alphabets between a and z are---\n";
	
	for(char lwalpCh = 'a'; lwalpCh <= 'z'; lwalpCh++)
	{
		cout << lwalpCh << " ";
	}
	
	return 0;
}

在此代码中，此 for 循环 (for(lwalpCh = 97; lwalpCh <= 122; lwalpCh++)) 迭代 a 和 z 的 ASCII 值，而不是在 a 和 z 之间迭代。

#include<iostream>
using namespace std;

int main()
{
	char lwalpCh;
	
	cout << "\n---List of Lowercase Alphabets between a and z are---\n";
	
	for(lwalpCh = 97; lwalpCh <= 122; lwalpCh++)
	{
		cout << lwalpCh << " ";
	}
	
	return 0;
}

---List of Lowercase Alphabets between a and z are---
a b c d e f g h i j k l m n o p q r s t u v w x y z 

使用 while 循环打印从 a 到 z 的字母的 C++ 程序

#include<iostream>
using namespace std;

int main()
{
	char lwalpCh = 'a'; 
	
	cout << "\n---List of Lowercase Alphabets between a and z are---\n";
	
	while(lwalpCh <= 'z')
	{
		cout << lwalpCh << " ";
		lwalpCh++;
	}
	
	return 0;
}

---List of Lowercase Alphabets between a and z are---
a b c d e f g h i j k l m n o p q r s t u v w x y z 

此 C++ 程序返回从 a 到 z 的字母代码允许用户输入起始小写字母。接下来，它打印从 startLwAlp 到 z 的小写字母。

#include<iostream>
using namespace std;

int main()
{
	char startLwAlp;
	
	cout << "\nPlease Enter the Starting Lowercase Alphabet = ";
	cin >> startLwAlp;
	
	cout << "\n---List of Lowercase between " << startLwAlp << " and z are---\n";
	
	for(char lwalpCh = startLwAlp; lwalpCh <= 'z'; lwalpCh++)
	{
		cout << lwalpCh << " ";
	}
	
	return 0;
}

Please Enter the Starting Lowercase Alphabet = j

---List of Lowercase between j and z are---
j k l m n o p q r s t u v w x y z 

此返回从 a 到 z 的字母的代码允许用户输入起始和结束小写字母。接下来，它打印从 startLwAlp 到 endLwAlp 的小写字母。

#include<iostream>
using namespace std;

int main()
{
	char startLwAlp, endLwAlp;
	
	cout << "\nPlease Enter the Starting Lowercase Alphabet = ";
	cin >> startLwAlp;
	
	cout << "\nPlease Enter the Starting Lowercase Alphabet = ";
	cin >> endLwAlp;
	
	cout << "\n---List of Lowercase between " << startLwAlp << " and " << endLwAlp << " are---\n";	
	for(char lwalpCh = startLwAlp; lwalpCh <= endLwAlp; lwalpCh++)
	{
		cout << lwalpCh << " ";
	}
	
	return 0;
}

Please Enter the Starting Lowercase Alphabet = f

Please Enter the Starting Lowercase Alphabet = v

---List of Lowercase between f and v are---
f g h i j k l m n o p q r s t u v
