在CLion IDE中使用C99标准进行编译和运行时，我得到的输出很奇怪；像这样：
Paint Layer Calculator
by : izder456
Room Width in Feet?1
Room Depth in Feet?2
Room Height in Feet?3
1 mil is 1/1000 of an inch
Paint Thickness in Mils?2
Calculating...
3332.000000 layers to fill your room with paint!!
& 1039.159058 gallons of paint
Process finished with exit code 0
我希望它看起来像这样：
Paint Layer Calculator
by : izder456
Room Width in Feet? 1
Room Depth in Feet? 2
Room Height in Feet? 3
1 mil is 1/1000 of an inch
Paint Thickness in Mils? 2
Calculating...
3332.000000 layers to fill your room with paint!!
& 1039.159058 gallons of paint
Process finished with exit code 0
我希望在提示和输入之间插入空格；我不希望他们像这样在行的开头。我还希望在倒数第二个问题和最后一个问题之前的行之间有一个空格，例如在C ++版本中。
我如何在scanf中格式化printf和main()以获得这种I / O格式？
您的帮助将不胜感激！
