String1 and String3 are not equal. 这里,如果我们先用 = 运算符比较 String1 和 String2。由于 String1 和 String2 都具有相同的长度,具有相同的字符序列,比较运算符返回 true,因此我们得到 String1 and String2 are equal.. 作为程序中第一个 if-else 块的输出。 同样,在第二个程序中,我们使用 == 运...

[ STRING1 > STRING2 ] 如果 “STRING1” sorts after “STRING2” lexicographically in the current locale则为真。 [ ARG1 OP ARG2 ] “OP” is one of -eq, -ne, -lt, -le, -gt or -ge. These arithmetic binary operators return true if “ARG1” is equal to, not equal to, less than...
