How can I get a binary sequence from rand() function of C?

I need to get a sequence of bits which will represent the work of LCG in rand() function in C, but I've no idea how to do it. Found a code example which looks like this

// C program for generating a 
// random number in a given range. 
#include <stdio.h> 
#include <stdlib.h> 
#include <time.h> 

// Generates and prints 'count' random 
// numbers in range [lower, upper]. 
void printRandoms(int lower, int upper,  
                             int count) 
{ 
    int i; 
    for (i = 0; i < count; i++) { 
        int num = (rand() % 
           (upper - lower + 1)) + lower; 
        printf("%d ", num); 
    } 
} 

// Driver code 
int main() 
{ 
    int lower = 0, upper = 1, count = 30; 

    // Use current time as  
    // seed for random generator 
    srand(time(0)); 

    printRandoms(lower, upper, count); 

    return 0; 
}

but I'm not sure if the sequence from this program will be an LCG binary sequence. Is there any other ways of getting bitstream from rand?
