Could I retrieve the datatype from a variable in C?

Question

Has a way to get the datatype in C?

For example:

int foo;

if (foo is int)
{
    // do something
}

or something like:

if (typeof(foo

The only time you wouldn't know the type is if the type of foo is defined by a typedef -- if that's the case, your example should reflect it. And why do you need to something dependent on the type? There may well be a way to solve your actual problem, but you haven't presented your actual problem.
