帮帮我看安康内这里面有什么不对的问题
#include <stdio.h>
void   main()
{
                  int   sum,num1,num2,num3,num4,num5,num6,num7,num8,num9,num10;
printf( "\n请输入一个数： ");
scanf( "%d,&sum ");
num1=sum*1;
num2=sum*2;
num3=sum*3;
num4=sum*4;
num5=sum*5;
num6=sum*6;
num7=sum*7;
num8=sum*8;
num9=sum*9;
num10=sum*10;
printf( "\n%d ",num1);printf( "\n%d ",num2);
printf( "\n%d ",num3);printf( "\n%d ",num4);
printf( "\n%d ",num5);printf( "\n%d ",num6);
printf( "\n%d ",num7);printf( "\n%d ",num8);
printf( "\n%d ",num9);printf( "\n%d ",num10);
}

[解决办法]
scanf( "%d,&sum "); 应该是 scanf( "%d ",&sum);
