sorry this is the code
Code:
#include <stdio.h>

int main(){
	 for (int i=0;i<4;i++){
		  printf("\n");
		  for (int j=0;j<(i+1);j++)
				printf("%d",(i+j));
	 }
getchar();
	 return 0;
}

and the output was
0
12
234
3456


instead of getting

0
12
345
6789


what's wrong in the code so I can get the right answer
