应该是这样@我啊找东西

@我啊找东西

#include<stdio.h>
int main()
{
printf("这是一个九九乘法表\n");
int a,b,c;
a=0;
b=1;
while(a>9)
{
a++;
{
while(b>a)
c=a*b;
b++;
printf("%dx%d=%d",a,b,c);
}
printf("\n");
}
}
求助，怎么改

#include<stdio.h>
int main()
{
printf("这是一个九九乘法表\n");
int a,b,c;
a=1;
b=1;
while(a<10)
{
b=1;
while(b<=a){
c=a*b;
printf("%dx%d=%d\t",a,b,c);
b++;
}
a++;
printf("\n");
}
}

#include<iostream>
using namespace std;
unsigned short int x(unsigned short int a,unsigned short int b)
{
if(b!=0)
return a/b;
else
return -1;
}
void main()
{
unsigned short int a,b;
cin>>a>>b;
cout<<x(a,b)<<endl;
} 能运行，但是不出来结果，结果是想输出A除B的值
