C语言编程计算油费

#include<stdio.h>

main()

{   int n

    float m,l

    while(1){

     printf("********************\n")

     printf("    1.  0号\n")

     printf("    2. 89号\n")

     printf("    3. 92号\n")

     printf("    4. 95号老改\n")

  侍颂判   printf("********************\n")

     printf("请选择(1-4):")

scanf("%d",&n)

if(n>0&&n<5){

    printf("请输入油量(L):")

 樱亮   scanf("%f",&m)

switch(n){

    case 1:l=m*7.23break

case 2:l=m*5.86break

case 3:l=m*7.66break

case 4:l=m*8.16break

}

printf("油价为:%.2f元\n",l)

} 

else

    printf("输入错误，请重新输入!\n")

}

}

如图所示，望采纳。。。。。。

下面那个回答是C++写的，如果你要C语慧悉言的答案的话如下：

#include <stdlib.h>前早乎

int main(void)

{

const float RATE=0.4

const float PRICE=7.74

const float GRASS_PER_MILE=7.5

float distance

float expense=0

printf("Please input the distance(with mile)\n")

scanf("%f",&distance)

expense=distance*PRICE*GRASS_PER_MILE/100+distance*RATE

printf("睁羡The expense is %f\n",expense)

return 0

}

运行结果如下：
