I have a struct: 开发者_C百科 struct KeyPair { int nNum; string str; }; Let\'s say I initialize my struct:
Today, with my great surprise, I discovered that When the sizeof operator is applied to a class, struct, or union type, the result is the number of bytes in an object of that type, plus any padding
In C# I\'vegot some \"safe\" API code related to UAC elevation.It involves getting the size of an enum (as follows)
The problem is simple: sizeof((u_char)value) returns 8. strlen fails. How to get a length of uchar\'s content?
This question already has answers here: In Java, wh开发者_开发技巧at is the best way to determine the size of an object?
I have 2 programs that share a header file. This header file defines a structure with a few members. There is then a #define: #define STRUCTURE_SIZE sizeof(OUR_STRUCTURE).
bool fp[81]; From my understanding fp should u开发者_开发技巧se ceil(81/8) bytes because it is in succession.
I have to get size of object which type I does not know. It\'s a template where I want to achieve sth like this:
In C, I need to know the size of a struct, which has function pointers i开发者_JS百科n it. Can I be guaranteed that on all platforms and architectures:
