C 结构和字符串

基本上，我在理解这个问题时遇到了一个问题

所以我试着刺激一些电梯

最初，所有电梯都在一楼，里面有0名乘客 和0使用率，即，尚未有人完成使用

给定一系列楼层编号，电梯将到达 一一对应楼层

如果电梯从一个较低的楼层到一个较高的楼层m，m 乘客将试图进入电梯。然而，一旦 电梯中的乘客人数达到15人，这是 电梯的容量，没有额外的乘客将能够 进入电梯

如果有p位乘客的电梯从一个较高的楼层到一个较低的楼层 n层、n层或p层，以较小者为准，乘客将离开 电梯离开电梯的实际乘客人数 应计入已完成的乘客人数 使用电梯

然后，我试着打印出相应的楼层、乘客数量和使用情况

Enter number of elevators: 1 
Enter sequence for elevator 1: 24653    
Elevator 1: 
Floor: 3 
Number of passengers: 4 
Usage: 8 
Most used elevator: 1

Enter number of elevators: 2
Enter sequence for elevator 1: 24653
Enter sequence for elevator 2: 798635
Elevator 1:
Floor: 3
Number of passengers: 4
Usage: 8
Elevator 2:
Floor: 5
Number of passengers: 5
Usage: 15
Most used elevator: 2

我需要帮助我的功能运行电梯和goToFloor，因为我不确定它们需要什么。我想我在电梯里做错了什么，但我不确定到底是什么

我知道字符2并不意味着整数2，但我似乎无法解决它

任何帮助都将不胜感激。谢谢

请具体解释你的问题，我不明白发生了什么事。解释你的期望和实际发生的事情。同样，forc=0；cvoid runElevators(elevator_t elevators[], char sequences[][MAX_LEN], int size) { int i, c; int prevFloor, currFloor; for(i = 0; i < size; i++) { for(c = 0; c < strlen(sequences[i]); c++) { prevFloor = elevators[i].floor; currFloor = sequences[i][c] - '0'; if (currFloor > prevFloor) { // Elevator going UP, passengers will enter the elevator int numPassengerToEnter; // Max capacity of elevator is CAPACITY (=15) numPassengerToEnter = CAPACITY - elevators[i].passenger; // At floor m, only m passengers (= currFloor) are available (to enter elevator) if (numPassengerToEnter < currFloor) { elevators[i].passenger += numPassengerToEnter; } else { elevators[i].passenger += currFloor; } } else if (currFloor < prevFloor) { // Elevator going DOWN, passengers will exit the elevator int numPassengerToExit; // Smaller of (Current floor number n) and (current number of passenger in elevator) will exit the elevator if (elevators[i].passenger < currFloor) { numPassengerToExit = elevators[i].passenger; } else { numPassengerToExit = currFloor; } elevators[i].passenger -= numPassengerToExit; } // Update current floor of elevator elevator[i].floor = currFloor; } }
