麻烦大家给我看看我这个小程序，我资质不够，还发现不了其中的错误！

#include"math.h"拆搭

main()

{

float p,d,f

printf("please inout consumption\袜御老n")

scanf("%f",&p)

if(p<100)

{m==0

f=p}

else if(p>告升=100&&p<200)

{m==o.o5

f=(1-0.05)*p}

else if(p>=200&&p<500)

{m==0.1

f=(1-0.1)*p}

else if(p>=500&&p<1000)

{m==0.15

f=(1-0.15)*p}

else(p>=1000)

{m==o.2

f=(1-0.2)*p}

printf("discount is %f,amount is %f",m,f)

}

试试看!

#include <stdio.h>

void main()

{

int age

printf("please input the child age:"脊睁)

scanf("%d",&age)

switch(age)

{

case 2:

case 3: printf("%d,enter the Lower class.\n",age)break

case 4: printf("%d,enter the Middle class.\n",age)break

case 5:

case 6: printf("樱拿岁敏局%d,enter the Higher class.\n",age)break

default : printf(" you chlid shuld goto more Higher class.\n")break

}

}
