C programming diamond shape for loops Problem and output sample is in the picture?

What will happen if you do not use break statement?
Everywhere in the code when there is no 'break', the running will continue with the next instruction. Example: for (i=0; i<3; ++i) { printf ("i=%d: ", i); switch (i) { case 2: printf ("two "); case 1: printf ("one "); case 0: printf ("zero "); } printf ("\n"); } The output: 0: zero 1: one zero 2: two one zero
