nextdate function problems

The Nextdate function describes a complex relationship, that is, the complexity of the logical relationship between input variables

The Nextdate function contains three variables, month, day, and year, and the output of the function is the date after the date Entered. The input variables are required to be integer values of month, day, and year, and the following conditions are Met:

Condition 1 1≤month≤12 Otherwise output, month out of range

Condition 2 1≤day≤31 Otherwise output, date out of range

Condition 3 1912≤year≤2050 Otherwise output: year out of range

String nextdate (int m,int d,int y)

Note The return value is a string.

Program Requirements:

1) first show "please enter date"

2) does not satisfy the condition 1, returns: "the month out of range", does not satisfy the condition 2, returns: "date out of range", does not satisfy the condition 3, returns: "the year out of range", if there are multiple unsatisfied, the first occurrence of unsatisfied error return Information.

3) If the conditions are met, the date of the second day is output: format "* * * * Month * * * day" (if you enter December 31, 2050, the normal January 1, 2051
