    structure declaration

    Hello All,

    Want to make typedef concept clear by implementing following
    Code:
    typedef node
    {
    	int a;
    	int b;	
    };
    
    typedef tot
    {
    	struct node theNode[32];  //  <-- Is there any memory allocated for this???   
                                                              
    };
    
    struct tot theTot;
    First two typedef strcture declartion do not allocate any memory at all. But last structure declaration will allocate total 256 bytes of memory( considering 4 bytes for int)

    Let me know, whether my above statement is correct.

    You're trying to typedef a struct? well, try something like this
    Code:
    typedef struct {
        int blah, bleh;
        char *str, ch;
    } idea;
    
    idea id[60];
