Question

编写程序以命令行参数形式输入两个整数，计算并输出两个整数相除的商和余数,程序中必须对无命令行参数或少

Answer 1

public class CatchsDemo {
public static void main(String args[]){
String x = "";
String y = "";
int i = 0;
int j = 0;
try{
x = args[0];
y = args[1];
i = Integer.parseInt(x);
j = Integer.parseInt(y);
}catch(IndexOutOfBoundsException e){
System.out.println("没有输入命令行参数");
System.exit(0);
}catch(NumberFormatException e){
System.out.println("输入数据格式不正确");
return;
}
finally{
System.out.println("输入的第一个数据为：" + x + " 输入的第二个数据为:" + y);
int sun = 0; int mun = 0;
sun = i / j;
mun = i % j;
System.out.println("两个数的商为：" + sun + " 两个数的余数为：" + mun);
}
System.out.println("here is the end of the program");
}
}

Answer 2

int main(int argc,char *argv[])
{
int x;
if(argc<3)
{
printf("请输入2个整数。");
return 0;
}
x=arg[0]%arg[1];
printf("商是 %d\n",x);
x=arg[0]-arg[1]*x;
printf("余数是 %d",x);
retrun 0;
}
