不知道哪里错啦

由于您没有提出你的问题点，所以我只能猜测是在 scanf 这里有问题，不建议写 "%d,%f"，因为这样你在输入的时候必须输入 0,1.1。建议你把逗号换为空格，

#include<stdio.h>

int main(void) {

    /*********Begin*********/

    int area;

    float weight, Price;

    scanf("%d %f", &area, &weight);

    if (area == 0) {
        if (weight <= 1) { Price = 10; }

        else {
            Price = 10 + (weight - 1) * 3;
        }

        printf("Price:%.2f\n",Price);

    } else if (area == 1) {
        if (weight <= 1) { Price = 10; }

        else { Price = 10 + (weight - 1) * 4; }

        printf("Price:%.2f\ni",Price);

    } else if (area == 2) {
        if (weight <= 1) { Price = 15; }

        else { Price = 15 + (weight - 1) * 5; }

        printf("Price:%.2f\n",Price);

    } else if (area == 3) {
        if (weight <= 1) { Price = 15; }

        else { Price = 15 + (weight - 1) * 6.5; }

        printf("Price:%.2f\n",Price);

    } else if (area == 4) {
        if (weight <= 1) { Price = 15; }

        else { Price = 15 + (weight - 1) * 10; }

        printf("Price:%.2f\n",Price);

    } else {
        printf("Error in Area\nPrice:0.00");

    }

    /*********End**********/

    return 0;

}

简单的改了改，问题很多。

1. 比较的时候应该使用 ==
2. scanf 的时候，参数应该传一个地址，所以有些要加取地址符
3. printf 的时候，参数要单独写出来
