Int a 1234 printf n a
NettetWrite a java recursive method called printNumPattern () to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. Ex. Nettet（在空间足够的情况下，当然遇到s1的空间不足以存放s2，另考虑），所以strcpy执行完后是“1234” strlen("1234") 就是4了 2 - strlen()函数：计算指定字符串 str 的长度，但不包括结束字符，遇到\0是结束计算，不算 \0，且从1开始计数。
