subscript out of range

See if the following example code is used: var studentlist:string[] = ["Zhang San", "John Doe", "Harry"] Studentlist[0] = "Zhuge Liang" var studentdictionary = [102: "Zhang San", 105: "John Doe", 109: "Harry"] STUDENTDICTIONARY[110] = "Dong Liu" When accessing arrays and dictionaries, you can use subscript access. Where the subscript of an array is an integ

Subscript ScriptSubscript scripts can be defined in the classes (class), struct (structure), and enumeration (enumeration) targets , which can be thought of as access to the collection (collection), list, or sequence (sequence shortcut , using the index of the subscript script to set and get values, you do not need to invoke the instance's specific assignment and access methods. For example, using the

Subscript swift allows us to define Subscripts for classes, struct, and enumeration to access a large number of attributes in a more convenient way. For example, both Array and Dictionary are struct, and swift engineers have provided code for subscript operations for these two types. Therefore, we can use myArray [2] in this way, read and Write the data stored in the struct. In addition, multiple

Multi-dimensional array subscriptThe subscript of multidimensional array is to use tuple to implement each dimension, if the tuple length is larger than the dimension, it will make an error, if small, then the default tuple is followed by: all Access is indicated;If a subscript is not a tuple, it is converted to a tuple, and the conversion of lists and arrays differs during the conversion process.A list is

1:c++ language can not check array subscript is out of bounds, if the subscript out of bounds will cause the program to crash, and the programmer in the editing code is difficult to find subscript out of bounds error. So how can you make an array subscript out-of-bounds detection? You can create an array template to ch

Use the field value as the array subscript For the awk command, any expression can be used as the subscript of the array. Therefore, fields can also be used as subscript. The program in the following example is used to calculate the number of times that all names appear in the 2nd fields, and a new form of for loop is introduced.For (index_value in array) statem

The [(subscript)] symbol in PHP can be applied not only to arrays and objects, but also to strings, assuming you are not aware of very easy errors.For example, to get a network interface, normally returns a JSON of the array structure, after parsing the result is:Array (' content ' = ' This is returned by interface ')After we have obtained the interface data, it is problematic to infer whether the content has a value by using the following statement:i

working, we need characters, strings. So how do numbers become strings? Here is a little article to do, I first thought of the ASCII code, but how to convert the ASCII code into a character? We need to introduce a function, but can we not introduce a new function? Let's think about it in a different way: try to generate an array, and then specify the subscript directly with the characters already in the array. For example, we can easily produce a "tr

Many classmates may have this question when learning the array, why does the subscript not start from 1? Isn't it more in line with People's daily habits starting from 1? In life we usually say a 1th, not a No. 0. Indeed, some computer languages, such as the early Pascal language, are the subscript for array elements starting from 1. is C language deliberately to be different? To figure this out, first look

This article mainly introduces the python in the sequence slice subscript problem related data, the article through the sample code introduced very detailed, has certain reference learning value to everybody, needs the friend to take a look below together. Objective In Python, a slice is a commonly used syntax, whether it is a tuple, a list, or a string, and the general syntax is: sequence[ilow:ihigh:step] # ihigh, step may be empty; For the sake of

in PHP [(subscript)]Symbols can be applied not only to arrays and objects, but also to strings, and are prone to errors if not noticed. For example, to obtain a network interface, normally returns a JSON of the array structure, after parsing the result is: Array (' content ' = ' This is returned by interface ') After we have obtained the interface data, we have a problem with the following statement to determine if the content has values: if
