#171776 - but Responding to: ???'s previous message |
Hi,Per,
1)i asked about !='0' vs !=0 . In topic context i think only second is proper. 2)You letter is very interesting (these sintax rules are known for me, but i never have thinked seriously about compiler side). I suppose original C implementation or ANSI standard defines what will compiler do with expression : " while ((a=b)!=0) .....". Is it true - that every C compiler will make assingment , and USE ASSIGNED value for comprasion ? regards |

| Yes. Should have said "warning" | 01/01/70 00:00 | |

Assign always spreads to the left, but mind the data type | 01/01/70 00:00 |
