Please help me fix the program I wrote for the following:

The month of February normally has 28 days, but if it's a leap year, it has 29 days. Write a program that asks the user to enter a year. The program should then display the number of days in February that year. Use the following criteria to identify leap years:

Determine whether the year is evenly divisible by 100. If it is, then it is a leap year if and only if it is also divisible by 400. For example, 2000 is a leap year, but 2100 is not.

If the year is not divisible by 100, then it is a leap year if and only if it is divisible by 4. For example, 2008 is a leap year, but 2009 is not.

Below is the code I have already written. Please help me identify what is wrong with it and how to fix it.

include int main () //establish variable int yearl; //asking for user input std::cout > yearl; //determine whether yearl is a leap year or not if yearl / 100&&yearl /400) std::cout
