我是照着书上的代码打的  这是什么情况呢

#include<stdio.h>
#include<stdlib.h>
void main()
{
    long i;
    float bonus,bonl,bon2,bon4,bon6,bon10;
    bonl=100000*0.1;
    bon2=bonl+100000*0.075;
    bon4=bon2+200000*0.05;
    bon6=bon4+200000*0.03;
    bon10=bon6+400000*0.015;
    printf("请输入利润i：");
    scanf("%ld",&i);
    if(i<=100000)
       bonus=i*0.1;
    else if(i<=200000)
       bonus=bonl+(i-100000)*0.075;
    else if(i<=400000)
       bonus=bon2+(i-200000)*0.05;
    else if(i<=600000)
       bonus=bon4+(i-400000)*0.03;
    else if(i<=1000000)
       bonus=bon6+(i-600000)*0.015;
    else
       bonus=bon10+(i-1000000)*0.01;
    printf("奖金是%10.2f\n",bonus);
    system("pause");  
       
}

1 和l 还要打错了

我滴个乖乖 还是不小心啊  多谢了
