如果我可以用 for 和 while 做一个循环，我应该选择哪个？
[为]
int num = 10;
int i;
for (i=0; i<num; i++)
{
/* ... */
}
[同时]
int num = 10;
int i = num;
while ( i-- )
{
/* ... */
}

最佳答案
for 和 while 之间的选择只是为了清楚起见:
K&R 。第 1 章 For 语句:
The choice between while and for is arbitrary, based on which seems clearer. The for is usually appropriate for loops in which the initialization and increment are single statements and logically related, since it is more compact than while and it keeps the loop control statements together in one place.
