Question

编写一个程序输入一个整数,判断它是奇数还是偶数

Answer 1

1.声明个变量n
2.获得输入附值到变量中
3.判断变量能否被2整除(n%2是否为1,如果等于1则是奇数,如果是0则是偶数)
%是取余数的意思
4.输出

Answer 2

private
sub
command1_click()
dim
a
as
string
dim
n
as
long
a
=
inputbox("输入一个正整数",
"输入")
n
=
clng(a)
if
n
mod
2
=
0
then
print
n;
"是偶数"
else
print
n;
"是奇数"
end
if
end
sub

Answer 3

#include<iostream>
using namespace std;
void main()
{
int n;
cin>>n;
if(n%2==0)
cout<<"偶数"<<endl;
else
cout<<"奇数";<<endl;
}
