It will be good if you can explain why the

first two codes do-not allow to print the output, whereas the last allows it to print the output!

```
1——
for(int i=0; i<=i++; i)
printf("%d\n",i);
2——
for(int i=0,j=0; i<=i++,j<=j++; i,j)
printf("%d\n",i);

3——
for(int i=0,j=0; i<=i++,j=i; i,j)
printf("%d\n",i);
```

I don’t think it has anything to do with ‘debugging or codeblocks’, does it?
