浙大PTA<基础编程题目集>：7-13 日K蜡烛图
题目内容
股票价格涨跌趋势，常用蜡烛图技术中的K线图来表示，分为按日的日K线、按周的周K线、按月的月K线等。以日K线为例，每天股票价格从开盘到收盘走完一天，对应一根蜡烛小图，要表示四个价格：开盘价格Open（早上刚刚开始开盘买卖成交的第1笔价格）、收盘价格Close（下午收盘时最后一笔成交的价格）、中间的最高价High和最低价Low。
如果Close<Open，表示为“BW-Solid”（即“实心蓝白蜡烛”）；如果Close>Open，表示为“R-Hollow”（即“空心红蜡烛”）；如果Open等于Close，则为“R-Cross”（即“十字红蜡烛”）。如果Low比Open和Close低，称为“Lower Shadow”（即“有下影线”），如果High比Open和Close高，称为“Upper Shadow”（即“有上影线”）。请编程序，根据给定的四个价格组合，判断当日的蜡烛是一根什么样的蜡烛。
输入格式
输入在一行中给出4个正实数，分别对应Open、High、Low、Close，其间以空格分隔。
输出格式
在一行中输出日K蜡烛的类型。如果有上、下影线，则在类型后加上with 影线类型。如果两种影线都有，则输出with Lower Shadow and Upper Shadow。
输入样例1
5.110 5.250 5.100 5.105
输出样例1
BW-Solid with Lower Shadow and Upper Shadow
输入样例2
5.110 5.110 5.110 5.110
输出样例2
R-Cross
输入样例3
5.110 5.125 5.112 5.126
输出样例3
R-Hollow
代码一：C语言
只对了三分之一
#include "stdio.h"
int main(){
double Open, High, Low, Close;
scanf("%f %f %f %f",&Open,&High,&Low,&Close);
if (Close < Open) {
if (Low < Open && Low < Close) {
if (High > Open && High > Close)
printf("BW-Solid with Lower Shadow and Upper Shadow");
else printf("BW-Solid with Lower Shadow");
}
else if (High > Open && High > Close) printf("BW-Solid with Upper Shadow");
else printf("BW-Solid");
}
else if (Close > Open){
if (Low < Open && Low < Close) {
if (High > Open && High > Close)
printf("R-Hollow with Lower Shadow and Upper Shadow");
else printf("R-Hollow with Lower Shadow");
}
else if (High > Open && High > Close) {
printf("R-Hollow with Upper Shadow");
}
else printf("R-Hollow");
}
else if (Close == Open) {
if (Low < Open && Low < Close) {
if (High > Open && High > Close)
printf("R-Cross with Lower Shadow and Upper Shadow");
else printf("R-Cross with Lower Shadow");
}
else if (High > Open && High > Close) printf("R-Cross with Upper Shadow");
else printf("R-Cross");
}
return 0;
}
代码二：Python
这个是正确的
# -*- coding: utf-8 -*-
Open, High, Low, Close = input().split()
Open = eval(Open)
High = eval(High)
Low = eval(Low)
Close = eval(Close)
if Close < Open:
if Low < Open and Low < Close:
if High > Open and High > Close:
print("BW-Solid with Lower Shadow and Upper Shadow")
else:
print("BW-Solid with Lower Shadow")
elif High > Open and High > Close:
print("BW-Solid with Upper Shadow")
else:
print("BW-Solid")
elif Close > Open:
if Low < Open and Low < Close:
if High > Open and High > Close:
print("R-Hollow with Lower Shadow and Upper Shadow")
else:
print("R-Hollow with Lower Shadow")
elif High > Open and High > Close:
print("R-Hollow with Upper Shadow")
else:
print("R-Hollow")
elif Close == Open:
if Low < Open and Low < Close:
if High > Open and High > Close:
print("R-Cross with Lower Shadow and Upper Shadow")
else:
print("R-Cross with Lower Shadow")
elif High > Open and High > Close:
print("R-Cross with Upper Shadow")
else:
print("R-Cross")
