Type of variables mer ,tmpmonth, tmpday,tmphour,tmpminute

[nnnnn]

type of variables " mer ,tmpmonth, tmpday,tmphour,tmpminute"

May you kindly help me with :

1 . the type of following variables ( in FORTRAN ) ?

mer ,
tmpmonth, tmpday, tmpyear and
tmphour,tmpminute,tmpsecond,tmphund

2 . " Warning: Variable MER is used before its value has been defined "
how it must be defined ? and also about all above variables .

Much much thanks

For 1, I don't know if the current versions of FORTRAN still do this, but the older versions, like FORTRAN 77, used to assocation types with variable names. Names that started with i, j, k, l, m, or n were INTEGER. Variable names that started with other letters were REAL.

So, if that rule is still applicable, mer is of type INTEGER, and all the others are of type REAL.

2. You should never use a variable before it has been defined; i.e., given a value.

Hello! I would be happy to help you with your questions.

1. The type of variables in FORTRAN is determined by the data type declaration. Without knowing the specific data type declaration for each variable, it is difficult to determine the exact type. However, based on the variable names, it is likely that "mer" is a numeric variable, while "tmpmonth", "tmpday", and "tmpyear" are likely to be integer variables. "tmphour", "tmpminute", "tmpsecond", and "tmphund" could be either integer or floating-point variables, depending on how they are used in the program.

2. The warning message "Variable MER is used before its value has been defined" means that the variable MER is being used in the program before a value has been assigned to it. To fix this, you need to assign a value to the variable before using it in the program. This applies to all variables in the program - they must be defined and given a value before being used. This can be done by using an assignment statement in the program, such as "MER = 0" to assign a value of 0 to the variable MER. It is important to properly define and assign values to all variables in a program to avoid any errors or unexpected results.

I hope this helps answer your questions. Best of luck with your programming!
