5rabbit question

i would have like to count how many bunnies are born each month
but the number of rabbits is regular,and it is better for me to use numbers to solve the problem

#include<stdio.h>
int main(){
    int i,j=1;
    int k;
    for(k=1;k<10;k++){
        printf("%d\t%d\t",i,j);
        i=i+j;
        j=i+j;
    }
}
