可能是我打开题目的姿势不对，我从题单进来的，说好的顺序结构，一大堆if是怎么回事，for循环都出来了，说好的顺序结构呢... 这题让没学分支结构的宝宝怎么办？ 这题用顺序结构怎么解？ 折腾一晚上，自己写了一个 请大家帮忙看看

#include <iostream>
#include <string>
using namespace std ;

int main() {
    string hour[24] = {"07","06","05","04","03","02",
    "01","00","23","22","21","20","19","18","17","16",
    "15","14","13","12","11","10","09","08"} ;
    double S , V ;
    int h , M , m1 , m2 ;
    cin >> S >> V ;
    h = 1440 - ( 1440 - 10 - S / V ) ;
    h = h / 60 ;
    M = 1440 - 10 - S / V;
    M = M % 60 ;
    m1 = M / 10 ;
    m2 = M - ( m1 * 10 ) ;
    cout << hour[h] << ":" << m1 << m2 ;
}
