如果我输入最多3条记录，我想这样显示

Name        Gender    Birthdate       Age //I want this to display in my output

joselito male 2001年11月28日19岁//如果我输入3条记录，我想要这个输出，尽管输出中的生日、生日和生日是分开的，但它们必须混合joselito male 2001年11月28日19岁joselito male 2001年11月28日19岁
我想通过减去2021年的出生年份来显示年龄。
但它看起来像这样，如果我在max记录中输入3

Name        Gender    Birthdate       Age //But it looks like this when i run the program
Joselito    Male      Nov. 28.0000, 2001.00000 //and error
