数字应为 18 个字符宽,4 位精度,并且需要采用固定格式。不要使用制表符 (\t) 来输出值............这是我得到的输出:
-30 100 20
Fahrenheit Celsius kelvin
-30.0000 -34.4444 238.7056
-10.0000 -23.3333 249.8167
10.0000 -12.2222 260.9278
30.0000 -1.1111 272.0389
50.0000 10.0000 283.1500
70.0000 21.1111 294.2611
90.0000 32.2222 305.3722
我在 Fahrenheit 列中的数字没有正确对齐........我希望我的输出看起来与这些完全一样 这是一个带有有效输入的示例运行:
-30 100 20 输出将是:
Fahrenheit Celsius Kelvin
-30.0000 -34.4444 238.7056
-10.0000 -23.3333 249.8167
10.0000 -12.2222 260.9278
30.0000 -1.1111 272.0389
50.0000 10.0000 283.1500
70.0000 21.1111 294.2611
90.0000 32.2222 305.3722
考虑这个输入: 100.5 110.4 5 有效输出将是:
Fahrenheit Celsius Kelvin
100.5000 38.0556 311.2056
105.5000 40.8333 313.9833
我被卡住了。请帮忙
