The definition of an array in C is a way to group together several items of the same type. These elements may have user-defined data types like structures, as well as standard data types like int, float, char,
- **C. `int foo[10];`** 错误写法。在Java中,声明数组时无法直接指定长度,数组容量需在初始化时确定(如`new int[10];`)。- **D. `Object[] foo;`** 声明了一个`Object`类型数组,与题目要求的`int`类型不匹配。- **E. `Object foo[10];`** 语法错误(同C),`Object`与后续写法不匹配...
The sample code below demonstrates building an array that contains function addresses and calling those functions. C++ Copy /* * Compile options needed: none */ #include <stdio.h> void test1(); void test2(); /* Prototypes */ void test3(); /* array with three functions */ v...
- **类型[] 变量名**(如选项A:`int[] foo;`)- **类型 变量名[]**(如选项B:`int foo[];`)**错误选项分析:**1. **选项C(`int foo[10];`)**:Java不允许在声明时直接指定数组大小,数组大小应在初始化时通过`new`关键字指定。2. **选项D(`Object[] foo;`)**:声明的是一个Object类型数组...
varmyArray = Enumerable.Empty<string>().ToArray(); Use the Repeat Method We can also use theEnumerable.Repeat()method to repeat the empty string 0 times and then convert it to an array using theToArray()method: varmyArray = Enumerable.Repeat("",0).ToArray(); ...
CsharpProgrammingServer Side Programming Declare a char array and set the size − char[] arr = new char[5]; Now set the elements − arr[0] = 'h'; arr[1] = 'a'; arr[2] = 'n'; arr[3] = 'k'; arr[4] = 's'; Let us see the complete code now to declare, initialize...
B、declare -a arrayC、declare -x array 相关知识点: 试题来源: 解析 B declare [+/-][选项] 变量名 选项: -:给变量舍得类型属性 +:取消变量的类型属性 -a:将变量声明为数组型 -i:将变量声明为整型 -x:将变量声明为环境变量 -r:将变量声明为只读变量 -p:查看变量的被声明的类型...

解析 C 在Visual FoxPro中,声明数组的命令有DIMENSION和DECLARE。DIMENSION和DECLARE功能完全相同,均用于定义一维或二维数组。ARRAY并非Visual FoxPro的合法数组声明命令,因此排除选项A和B。选项D仅提到DIMENSION,但遗漏了DECLARE,因此错误。正确答案为C。反馈 收藏 ...
