5.14章节，求大神帮忙改下程序错误顺便交一些从编译器错误反馈中提取程序错误信息的基础技巧

#include <stdio.h>

int taxiFare(km)

{

int distance,float fare;

if(distance<=3)

float fare=14;

else

taxiFare=taxiFare(km-1)+2.3;

return fare=fare*2;

}

int main()

{

int 12kmFare=taxiFare(12);

printf("小明每天打车的总费用为%f元”,12kmFare);

return 0;

}

另附编译器出错提示，能不能帮我说明一下编译器指出的错误有哪些，怎样从编译器的错误报告中自己修改程序错误?

你这错误还不少啊！找了半天，方便采纳下吧
#include <stdio.h>
int taxiFare(int km)//参数没有写int类型 
{
    int distance; 
	float fare;
    if(distance<=3)
        float fare=14;
    else 
        fare=taxiFare(km-1)+2.3;//变量书写错误 
        return fare=fare*2;
}
int main()
{
    float a12kmFare=taxiFare(12);//命名错误，数字不能打头 （类型写错） 
    printf("小明1每天打车的总费用为%f元",a12kmFare);//“”引号使用错误 
    return 0;
}
