construct.However, if you changeClass a{public : A () : I (1) { } A (const A a) { } int i; int i1; int i2;}; A func () { a A; return A;} void Func1 () { A B = func ();}　　Compilation can pass, why. Because the const a is passed in means that the object constructed with this value does not modify the value. Or can not be modified. Therefore, you can use this value to construct other objects.But the problem is still a, a is no longer on the stack, how to

Oracle user password. Check the limits.conf file parameters, in my version, there is no need to change. But to add a line of Oracle stack 10240 Check the sysctl.conf parameter and do not need to modify it in my version. Finally, run the next file.

1. Ldr and STR:(1) Ldr as an instruction, called a register loading instruction. Loads the in-memory value into the register.(2) Ldr, as a pseudo-instruction, implements a 32-bit constant or address value to be loaded into the register. A constant or address value label that is loaded after must have a "=" before the compiler replaces the pseudo-directive with the instruction implementation.(3) Str saves the value in the register to the memory unit.2. A long pseudo-operation that assigns a value
