为什么这段代码不起作用？

基本思路：

每辆车可以坐4个人。每列火车的第一节车厢长 10 英尺，随后的每节车厢长 8 英尺。火车只能占据总轨道长度的25%。
目标是打印出可以填充火车轨道的最大人数，用户输入最大轨道长度和最大火车长度。

//This program calculates the maximum number of people that can be on the
//track at one time.  

int main(void) {

    int max_people_train;
    int num_cars_train;
    int total_num_trains;
    int max_length_track;
    int max_length_train;
    int max_people_track;
    int prev_max_people_track;
    int prev_total_num_trains, i;

    printf("Please enter the track length:\n");
    scanf("%d", &max_length_track);

    printf("Please enter the max length of the train:\n");
    scanf("%d", &max_length_train);

    for (i=10; i<=max_length_train; i+8) {
        num_cars_train = ((i-10)/8 +1);
        max_people_train = (num_cars_train)*4;
        total_num_trains = max_length_track/i;
        max_people_track = total_num_trains*max_people_train;

        prev_max_people_track = prev_total_num_trains * max_people_train;
        prev_total_num_trains = max_length_track/(i-8);

        if (prev_max_people_track > max_people_track)
            max_people_track = prev_max_people_track;
    }



    printf("Your ride can have at most %d people on the track,\n", max_people_track);
    printf("This can be achieved with trains of %d cars.\n", num_cars_train);


    system("pause");
    return 0;
}

我猜这与此有关：

for (i=10; i<=max_length_train; i+8) {
//  ============================^^^ WTF ?

尝试：

for (i=10; i<=max_length_train; i+=8) {
