在C++中， 可以用isdigit()判断一个字符是否是数字，可以用isalpha()判断一个字符是否是字母，还有很多，都在<cctype>头文件中   而类似的方法在JAVA

  #include <cstdio> #include <algorithm> #include <cstring> #include <cctype

#include<iostream> #include<cctype> #include<cstdlib> #include<cstdio> #include

#include<iostream> #include<cctype> #include<cmath> #include<cstring> #include

#include<iostream> #include<cctype> #include<cmath> #include<cstring> #include

#include<iostream>、 #include<cctype> using namespace std; int main(){ char a[36]

#include<iostream> #include<cctype> #include<algorithm> using namespace std;

list::sort #include <iostream> #include <list> #include <string> #include <cctype

#include <iostream> #include <cstdio> #include <cctype> #include <cstring>

(具体方式参见第3章模板) 1.编写一个小程序，读取键盘输入，直到遇到@符号为止，并回显输入（数字除外），同时将大写字符转换为小写，将小写字符转换为大写（别忘了cctype函数系列）。

c++中应该是#include <cctype> c中应该是#include <ctype.h> 以下为字符函数库中常用的函数： 函数名称 返回值 isalnum

http://www.cplusplus.com/reference/cctype/   函数名称 返回值 isalnum() 如果参数是字母数字，即字母或数字，该函数返回true

Kruskal 算法的实现 #include <iostream> #include <string> #include <iomanip> #include <cctype

也有两种做法： 做法一： #include<iostream> #include<cstdio> #include<cstring> #include<cctype

C++实现代码： #include<iostream> #include<string> #include<cctype> using namespace
