How to generate binary numbers from 1 to N in C

Answer 1

#include <stdio.h>
 
#define LEN 100
 
void printBinaryNumber(int n) {
    int binary[LEN], i = 0;
     
    while (n > 0) {
        binary[i] = n % 2;
        n = n / 2;
        i++;
    }
    for (int j = i - 1; j >= 0; j--)
        printf("%d", binary[j]);
    printf("\n");
}
void generateBinaryNumbers(int n) {
    for (int i = 1; i <= n; i++) {
        printBinaryNumber(i);
    }
}
 
int main() {
    int N = 15;
 
    generateBinaryNumbers(N);
    
    return 0;
}
