Could you please help me construct some of these basic C programs?
I apologize for these questions but I have fallen desperately behind my class and can't seem to understand some of these and feel to embarrassed to ask for help there! :confused:
How would I write this basic C program?
Using the sizeof(<variable or type>) function and the print function, write a program that displays the size of several variable types.
An integer array with 3 elements
a character array with 4 elements
a float array with5 elements
a double array with 6 elements
Could you please explain this to me?

printf("%d\n", sizeof(char) );
The rest you'll have to figure out for yourself.

Perhaps you should post the one's you are specifically having trouble with, along with what you have achieved yourself.
FWIW, if you're that far behind, you really need to talk to your tutor, to try and work out some kind of catch-up plan.
Your homework is beginning of the book basic stuff, there are much harder things coming. Unless you can put the effort in to catch up quickly, you're just going to end up failing.

Am I heading in the right direction?
int size_of_int = sizeof(int);
int = ;
int size_of_float = sizeof(float);
float = ;
int size_of_char = sizeof(char);
char = ;
int size_of_double = sizeof(double);
double = ;
printf = ("%d"size_of_int, size_of_float, size_of_char, size_of_double);

Paste it into your compiler, and find the answer in a few seconds (rather than waiting for what could be hours).

And be sure to set your compiler to display warnings, so that it can scold you for not returning an int as you had promised.

No. The right direction would be a series of statements similar to that Salem posted - he's done the first one for you! You have severely overcomplicated the solution.
