    help with random number generator

    I have an assignment for school, to make a long story short I'm having trouble with the random number generator. I get two errors saying "error: expected expression before ‘=’ token" they give the line number of the printf statment "printf("%d\n", rand() % (HIGH - LOW + 1) +LOW );". I dont understand what the problem is can anyone please help me.


    Code:
    	do
    	{
    			
    		/* gets time and convert seconds to unsigned int */
    		time_t now;
    	        time(&now);
    		srand(now);
    		
    		rand();
                    /*sets the bounds*/
    		printf("%d\n", rand() % (HIGH - LOW + 1) +LOW );
    		
    	/*	printf("%d", randnum); */
    		
    
    		++count;
    
    	} while (count <= 11);

    My Hat of Guessing says that you did
    Code:
    #define HIGH = 10
    instead of the correct
    Code:
    #define HIGH 10
    (or whatever your number is).
