how get get rid of this warning?

when i compiled in "code blocks" compiler my
code showed no wornings
but when i compiled with visual studio 2005 i got 4 warnings of this type:

warning C4996: 'scanf': This function or variable may be unsafe. Consider using scanf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

for each warning i get my grade cut off by a significant number
how to fix this??

Go to Project -> Properties -> Configuration Properties -> C/C++ -> Preprocessor

Then in the "Preprocessor Definitions" field set _CRT_SECURE_NO_WARNINGS so as to disable those needless warnings.

so there is no problem??
i thought maybe i use long variable
and do %d
in the scanf
or the opposite case when i enter %ld
in the scanf
but the variable is integer
??

but i checked
for every integer i wote %d in the scanf
and in long i got %ld in the scanf

so this is not a sign for the program to crush in some case?

The problem is that you are using scanf(), and the Microsoft compiler has an arguably safer version that is non-standard and which it suggests to you by default through irritating warnings.

thanks :)
