题目分析

此题考查了 if else 与 ASCII 编码。

代码实现

#include<cstdio>
int main(){
    char c;
    scanf("%c",&c);
    if(c>='0'&&c<='9')printf("数字字符");
    else if(c>='a'&&c<='z')printf("小写字母");
    else if(c>='A'&&c<='Z')printf("大写字母");
    else printf("其它字符");
    return 0;
}

记得给五星好评哦喵~ 谢谢客官啦~

#include<bits/stdc++.h>
using namespace std;
int main(){
	char ch;
	cin>>ch;
	if('a'<=ch and ch<='z'){
		cout<<"小写字母";
	}else if('A'<=ch and ch<='Z'){
		cout<<"大写字母";
	}else if('0'<=ch and ch<='9'){
		cout<<"数字字符";
}else{
	cout<<"其它字符"; 
}
	return 0;
}

#inlude<its/stdc++.h> using namespce std; int main(){ char ch; cin>ch; if('a'<=ch and ch<='z'){ cou<<"小写字母" }ele if('A'<=ch and ch<='Z'){ out<<"大写字母"; }else if('0'<=ch and ch<='9'{ cout<<"数字字符"; }else{ cut<<"其它字符"; } return 0; }

#include<bits/stdc++.h> using namespce std; int main(){ char ch; cin>>ch; if('a'<=ch and ch<='z'){ cout<<"小写字母" }ele if('A'<=ch and ch<='Z'){ cout<<"大写字母"; }else if('0'<=ch and ch<='9'){ cout<<"数字字符"; }else{ cout<<"其它字符"; } return 0; }
