You are not calling your functions correctly. The function getStudent() returns a Student datatype, so you need to store the value returned by this function in a variable of type Student.

Similarly the function displayStudent() requires a Student datatype input so you need to supply that input variable to that function.

int main()
{
	Student x;

	Student myStudent = getStudent();
	displayStudent( myStudent ); // do not put void here.


	cin.get();
	cin.get();
	return 0;

What is the error that it shows?
azntrindo (43)
in the errorlist on visual studios it shows 46 errors
mostly with error c2228 and 2065
example
one of the errors is
error C2228: left of '.state' must have class/struct/union
error C2065 'x' is undeclared

Try moving the following struct definition to the beginning of your program, before the functions.
