这是我 11 年级的计算机课。我正在创建一个将水平转换为百分比的程序。 这是我为我的 python 代码制作的列表，它向用户显示他们进入一个级别(例如 3+)时的百分比，但我想知道我是否可以在 C++ 中做这样的事情。
grade= {}
grade['R-'] = '0%'
grade['R'] = '30%'
grade['R+'] = '40%'
grade['1-'] = '50%'
grade['1'] = '53%'
grade['1+'] = '57%'
grade['2-'] = '60%'
grade['2'] = '63%'
grade['2+'] = '67%'
grade['3-'] = '70%'
grade['3'] = '73%'
grade['3+'] = '77%'
grade['4-'] = '80%'
grade['4'] = '87%'
grade['4+'] = '95%
