Re: [閒聊] 尋求比nest-if更優美的解決辦法
if(data != NULL) {
if(checkData(data) == 0) {
if(modifyData(data) == 0) {
if(fireDataChanged(data) == 0) {
if(saveDataIntoFile(data) == 0) {
printf("Finally succeed...");
}
else printf("Data storage failed.");
}
else printf("Observer call failed.");
}
else printf("Data modification failed.");
}
else printf("Data is invaild.");
}
else printf("Data not found.");
如果這樣呢?
if(data == Null) printf("Data not found.");
else if(checkData(data) != 0) printf("Data is invaild.");
else if(modifyData(data) != 0) printf("Data modification failed.");
else if(fireDataChange(data) != 0) printf("Observer call failed.");
else if(saveDataIntoFile(data) != 0) printf("Data storage failed.");
else printf("Finally succeed...");
不知道會不會比較好XD
新手 有錯請不吝指證 謝謝:)
