Thank you guys!

This was actually very obvious.



i < UINT_MAX


will always be true since UINT_MAX is the upper limit for unsigned int. Declaring i as unsigned long fixes the problem.

I have written a little program to find out the amount of bits in an unsigned int. By some reason the program prints nothing. It just goes into an infinite loop. What is wrong?

ar is an array of 6 int.
&ar is a pointer to an array of 6 int.

The value ar is the address of the first element in the array.

First of all, have you designed any algorithm for calculating the age?

Every array must have a size.



#define BUFSIZ 4096 /* for instance */

...

char buff[BUFFSIZ];

while ( fgets( buff, BUFSIZ, fp ) != NULL ) {
fputs( buff, stdout );


The first line will go through all lines in the file, one at a time, till fgets( ) returns NULL.

When does fgets(...

I think a function name, much like an array name, is just a pointer.



int func( void );


func is a pointer to a function, with no arguments, returning int.

You don't need to typedef your structure.

The first argument of fgets() must be a char *.
