请用c语言编写上述信息

为了用C语言编写一个简单的程序来计算广东省高速公路的费用，首先我们需要创建一个结构体来存储车辆的信息，并编写函数来根据输入的数据返回收费系数。这里是一个基础示例，假设我们已经有了一个名为`VehicleInfo`的结构体，其中包含座位数（`passengerCount`）和轴数（`axlesCount`）字段：

#include <stdio.h>

// 定义车辆信息结构
typedef struct {
    int passengerCount;
    int axleCount;
} VehicleInfo;

// 计算客车费用函数
double calculatePassengerFee(VehicleInfo vehicle) {
    double baseFee = 0;
    
    // 根据座位数分段计算
    if (vehicle.passengerCount <= 9)
        baseFee = 1;
    else if (vehicle.passengerCount <= 19)
        baseFee = 2;
    else if (vehicle.passengerCount <= 39)
        baseFee = 1.5;
    else
        baseFee = 2; // 40座以上
    
    return baseFee;
}

// 计算货车费用函数
double calculateTruckFee(VehicleInfo vehicle) {
    double feePerAxle = 0;

    switch (vehicle.axleCount) {
        case 2:
            feePerAxle = 2.1;
            break;
        case 3:
            feePerAxle = 3.16;
            break;
        case 4:
            feePerAxle = 3.75;
            break;
        case 5:
            feePerAxle = 3.86;
            break;
        case 6:
            feePerAxle = 4.09;
            break;
        default:
            // 处理未知轴数情况
            feePerAxle = 0;
            printf("Unknown number of axles for the truck.\n");
    }

    return feePerAxle * vehicle.axleCount;
}

int main() {
    VehicleInfo input;
    printf("Enter the number of passengers for a passenger car and the number of axles for a truck:\n");
    scanf("%d %d", &input.passengerCount, &input.axleCount);
    
    double passengerCharge = calculatePassengerFee(input);
    double truckCharge = calculateTruckFee(input);

    printf("For a %d-seat passenger car, the fee is %.2f yuan/km.\n", input.passengerCount, passengerCharge);
    printf("For a truck with %d axles, the fee is %.2f yuan/km.\n", input.axleCount, truckCharge);
    
    return 0;
}

这个程序会提示用户输入车辆的乘客数和轴数，然后计算费用。请注意，这只是一个简化版本，实际的收费规则可能会更复杂，包括计费单位、优惠政策等细节。在实际项目中，建议参考官方文件或API获取最新准确信息。
