Question

C++做一个降序数的判断，遇到了电问题

#include<iostream.h>
void main()
{int x,t;
int sign=0;
cout<<"number"<<endl;
cin>>x;
do
if(x%10>=t)
{t=x%10;
x/=10;}
else
{sign=1;
break;}
while(x%10==0);
if(sign==1)
cout<<"No"<<endl;
else
cout<<"YES"<<endl;
}
以上就是代码
sign等于是一个判断的数值，X是想要判断的数
t初始为0跟x&
#include<iostream.h>
void main()
{int x,t;
int sign=0;
cout<<"number"<<endl;
cin>>x;
do
if(x%10>=t)
{t=x%10;
x/=10;}
else
{sign=1;
break;}
while(x%10==0);
if(sign==1)
cout<<"No"<<endl;
else
cout<<"YES"<<endl;
}

Answer 1

#include<iostream.h>
void main()
{
int x,t = 0;
int sign=0;
cout<<"number"<<endl;
cin>>x;
do
{
if(x % 10 > t)
{
t=x % 10;
x /= 10;
}
else
{
sign=1;
break;
}
}
while(x != 0);
if(sign==1)
cout<<"No"<<endl;
else
cout<<"YES"<<endl;
}

Answer 2

t没赋值，
if(x%10>=t)
就会判断不准。
电脑会随机分配一个数给t。

Answer 3

t 没初始化
