1、首先，需要定义数组，数组常用类型有int型，float浮点型，char字符型等，输入即可定义。2、然后就是数组的名称了，可以自己定义，但是要符合相应规则。3、一般在数组定义阶段就确定数组的大小，输入数字即为数组大小，如下图所示。4、然后，可以对数组进行初始化，在花括号{}中输入即可。5、如果初始化...
请注意,c_arr 的长度为 21 个字符,并且初始化为 20 个 char 长字符串。因此,数组中的第 21 个字符保证是\0 字节,使内容成为一个有效的字符串。 #include <stdio.h> #include <stdlib.h> #include <string.h> void printCharArray(char *arr, size_t len) { printf("arr: "); for (size_t i...

指针方法的优点是,array的地址每次装入地址p后,在每次循环中只需对p增量操作。在数组索引方法中,每次循环中都必须根据t值求数组下标的复杂运算。 2、使用尽量小的数据类型 能够使用字符型(char)定义的变量,就不要使用整型(int)变量来定义;能够使用整型变量定义的变量就不要用长整型(long int),能不使用浮点型(flo...

I have a large array in C (not C++ if that makes a difference). I want to initialize all members of the same value. I could swear I once knew a simple way to do this. I could use memset() in my case, but isn't there a way to do this that is built right into the C ...
If you specify an array size that is shorter than the string, the extra characters are ignored. For example, the following declaration initializes code as a three-element character array:复制 char code[3] = "abcd"; Only the first three characters of the initializer are assigned to code. ...
