Summary of problems related to initialization of C string arrayIn C programming, when we declare a string array, we often need to initialize it to an empty string. The following three ways are summed up:
(1) Char str[10]= "";
(2) Char

"introduction to arrays"An array is actually an ordered set of data of the same type, and its image is represented as a linear table. When storing data, a contiguous storage space is first allocated in memory, and each element is stored sequentially
Main (){Char s[30];strcpy (S, "good news!"); /* Assign string to array */...}The program at compile time, when encountering Char s[30] This statement, the compiler will be in memory somewhere left30 bytes in a row, and assigns the address of the
If you want to save a set of data with the same type, you can use an array.Definition of arrays and memory allocationThere are two types of syntax for defining arrays in Java:Type arrayname[];Type[] Arrayname;Type is any data type in Java, including
Usually we are exposed to most of the static array, in fact, in many cases, the static array does not meet the actual needs of our programming, for example, I need to be in the process of running the program to add data dynamically to the array,
