代碼確實有問題，你這個沒有使用拋出，只是try執行那個函數是打印了語句，并沒有用到throw，所以不算是異常處理

#include?<iostream>
#include?<string>
#include?<stdlib.h>
using?namespace?std;
/**?*?定義函數division?*?參數整型dividend、整型divisor?*/
int?division(int?dividend,?int?divisor)
{???
?if(0?==?divisor)	
?{????????
?//?拋出異常，字符串“除數不能為0”	
?	throw?string("除數不能為0");	
?}	
?else	
?{	
?	return?dividend?/?divisor;
?}
}
int?main(void)
{
	int?d1?=?0;	
	int?d2?=?0;	
	int?r?=?0;	
	cin?>>?d1;	
	cin?>>?d2;????
	//?使用try...catch...捕獲異常	
	try	
	{	?
	???division(d1,d2);	
	}	
	catch(string?&e)	
	{	???
	?????cout<<e<<endl;
	}
	system("pasue");
	return?0;
}

誰能告訴我，為什么用了【代碼語言】，程序排版還是這么亂？？？

#include?<iostream>#include?<string>#include?<stdlib.h>using?namespace?std;/**?*?定義函數division?*?參數整型dividend、整型divisor?*/int?division(int?dividend,?int?divisor){????if(0?==?divisor)	{????????//?拋出異常，字符串“除數不能為0”		cout<<?string("除數不能為0");	}	else	{		return?dividend?/?divisor;	}}int?main(void){	int?d1?=?0;	int?d2?=?0;	int?r?=?0;	cin?>>?d1;	cin?>>?d2;????//?使用try...catch...捕獲異常	try	{	???division(d1,d2);	}	catch(string)	{	???	}	return?0;}
