WebFeb 3, 2024 · There are 6 basic ways to initialize variables in C++: int a; // no initializer (default initialization) int b = 5; int c( 6 ); int d { 7 }; int e = { 8 }; // initializer in braces after equals sign (copy list initialization) int f {}; // initializer is empty braces (value initialization) WebIn C++, both float and double data types are used for floating-point values. Floating-point numbers are used for decimal and exponential values. For example, // creating float type variables float num1 = 3.0f; float num2 = 3.5f; float num3 = 3E-5f; // 3x10^-5 // creating double type variables double num4 = 3.0; double num5 = 3.5; double num6 = 3E-5; // … Webint& r = const_cast( i); // 常量转换，将const int转换为int 重新解释转换（Reinterpret Cast） 重新解释转换将一个数据类型的值重新解释为另一个数据类型的值，通常用于在不同的数据类型之间进行转换。 重新解释转换不进行任何类型检查，因此可能会导致未定义的行为。 实例 int i = 10; float f = reinterpret_cast( i); // 重新解释将int类型转换 … eurythmics traduction
