OJ click to judge whether the date (year, month, and day) is valid
Description

Compile the isValid_date function. The function declaration is as follows:
Int isValid_date (int year, int month, int day); // function declaration that determines whether the date (year, month, and day) is valid. if the date is valid, 1 is returned. if the date is invalid, 0 is returned.
Add the isValid_date function definition on the basis of the following programs so that the program can be correctly executed.
When submitting, you only need to submit the definition code of the isValid_date function.

# Include <iostream>
Using namespace std;

Int isValid_date (int year, int month, int day); // function declaration that determines whether the date (year, month, and day) is valid

Int main ()
{
Int y, m, d; // defines three variables to store the input year, month, and day.
Cin> y> m> d;
Cout <y <"-" <m <"-" <d;
If (isValid_date (y, m, d) = 1)
Cout <"valid" <endl;
Else
Cout <"not valid" <endl;
Return 0;
}

Input

Enter three positive integers, which represent the year, month, and day of a date.

Output

Whether the date is correct, for example, whether the month is correct, and whether the month date is correct

Sample Input

2002 13 40

Sample output

2002-13-40 not valid

 

 

The Code is as follows:

# Include <iostream> using namespace std; int isValid_date (int year, int month, int day); // function declaration that determines whether the date (year, month, and day) is valid int main () {int y, m, d; // defines three variables to store the input year, month, and day cin> y> m> d; cout <y <"-" <m <"-" <d; if (isValid_date (y, m, d) = 1) cout <"valid" <endl; else cout <"not valid" <endl; return 0;} int isValid_date (int year, int month, int day) {int days, I; for (I = 1; I <= month; I ++) {if (I = 1 | I = 3 | I = 5 | I = 7 | I = 8 | I = 1 0 | I = 12) days = 31; else if (I = 4 | I = 6 | I = 9 | I = 11) days = 30; else if (year % 4 = 0 & year % 100! = 0) | year % 400 = 0) days = 29; else days = 28 ;} if (year >=0 & month >=1 & month <= 12 & day >=1 & day <= days) return 1; else return 0 ;}
