address, gender, just to distinguish different students. Identity columns are implemented in the following ways: If the data for a column is of a numeric type (such as an integer), you can define the column as an identity column. Once defined as an identity column, you also need to specify the identity seed and identity increment , respectively, and thedefault value is 1. After defining the columns of the table, each time the data is entered at a later time, the col

library defines an iterator type for each standard container. Iterator types provide a more generalized approach than subscript operations: All standard library containers define the appropriate iterator types, and only a few containers (such as arrays) support subscript operations. Because iterators are applicable to all containers, modern C + + programs tend to use iterators rather than subscript operations to access container elements.Iterators ar

Default (Can not write, but strongly recommended to write, code rigor ) is equivalent to the if else, and when all case does not match, execute default.3, If there is no code in the case, if you do not write break, it will run through the next code. 　　Problems merging multiple switch conditions: When the code for multiple case conditions is the same

Let's look at a simple example:If the entire program is likened to a "line", then the "line" must first have an entry, which is the invocation of the main function ("main (agc, argv);"), until the ret

C # programs execute on a line-by-line, top-down, with no missing code. In order for the program to execute according to the process designed by the developer, it is necessary to make the process of condition judgment, loop and jump, which need to realize the process control. The Process Control in C # contains four aspects of conditional statements, loop statements, jump statements, and exception handling.
