Initialization Wheninitializingan object ofarraytype, the initializer must be either astring literal(optionally enclosed in braces) or be a brace-enclosed list of initialized for array members: =string-literal(1) ={expression,...}(2)(until C99) ...

The initialization of constructors in a C application can occur even if the BSPCFG_ENABLE_CPP and MQX_ENABLE_CPP flags are not explicitly defined in the project files. This is because the initialization of constructors is typically handled by the C runtime startup code pr...
To initialize all values to 0, one approach is to use Solution 3. However, it's not possible to initialize arrays like this. For 2D arrays, use the syntax with curly braces on the right-hand side of the initialization statement. In the case of 1D arrays, you can't use C arrays like...
array<int, 100>, 100> c{};整个二维数组都会被初始化为零， 详细你可以搜索value initialization。
比如A a=1;就是隐式转换，而不是显示调用构造函数，即A a(1);。像A(1)这种涉及类型转换的单参数...

这实际上只是初始化数组的特殊语法:https://en.cppreference.com/w/c/language/array_initialization 可以使用字符串文本初始化char数组,这只相当于声明一个包含字符串中每个字符的数组(包括null终止符)。 如何将char数组的元素复制到char? 你可以直接做。如果你想复制一个特定位置的char,你可以使用 char c = sourc...
In the declaration grammar of an array declaration, the type-specifier sequence designates the element type (which must be a complete object type), and the declarator has the form: [ static(optional) qualifiers (optional) expression (optional) ] attr-spec-seq (optional) (1)...
