此方法接受一个string类型参数,但是却没有检测此数值是否 有足够的空间来拷贝数据。所以这里我们一般用 fgets() 方法将来的更好。 Answer: The hidden problem with the code above is the use of the function gets(). This function accepts a string from stdin without checking the capacity of buffer in w...
char string[10]; if( strlen( str1 ) <= 10 ) { strcpy( string, str1 ); } } 解答: 试题1 字符串 str1 需要 11 个字节才能寄存下(包括末尾 旳’\0’),而 string 只有 10 个字节旳空间,strcpy 会导致数组越 界; 对试题 2,假如面试者指出字符数组 str1 不能在数组内结束可以 给 3 分;...
