A bitwise copy is what you automatically get when you do not provide a copy constructor. The compiler simply provides code that copies the object without regard to the type of the members. This is dangerous if any of the members happen to be pointers, because then you have two pointers to the same object and, if you delete one, you wind up having the other pointing to an object that has been deleted.

What is use of l in c language?
Bitwise OR.
What are the conditions to swap in c plus plus without temporary?
You can swap two integers without temporary storage by bitwise exclusive-or'ing them in a specific sequence...a ^= b;b ^= a;a ^= b;
How many types of logical operators in c only?
There are three logical operators in C; AND (&), OR (|), and NOT (^). These are the bitwise versions. The combinatorial versions are &&, , and !.
What are the various operators available in c language?
There are eight types of operators which are used in C language.These are- 1.Arithmetic operator 2.Assignment operator 3.Relational operator 4.Increment/Decrement operator 5.Bitwise operator 6.Logical operator 7.Conditional operator 8.Additional operator 1.Arithmetic operator:Arithmetic operators are mathmetical operator.These are addition,Subtraction,Multiplication and divison. 2.Assignment operator:Assignment operators are used to store the result of an expression to a variable.
What is the C plus plus expression and operator precedence?
Precedence is determined by operators only. Every operator has a precedence in the range 1 through 17, where 1 has the highest precedence. All precedences have left-to-right associativity except 3 and 15 which are right-to-left. Precedence 1: scope-resolution operator Precedence 2: postfix increment/decrement, function-style type cast, function call, array subscripting and selection by reference or pointer. Precedence 3: prefix increment/decrement, unary plus/minus, logical and bitwise NOT, C-style cast, dereferencing, address-of, sizeof, new/new [] and delete/delete []. Precedence 4: pointer to member. Precedence 5: multiplication, division and modulo. Precedence 6: addition and substraction. Precedence 7: bitwise left/right shift. Precedence 8: relational operators (<, <=, > and >=). Precedence 9: equal/not equal operators (= and !=) Precedence 10: bitwise AND Precedence 11: bitwise XOR Precedence 12: bitwise OR Precedence 13: logical AND Precedence 14: llogical OR Precedence 15: ternary conditional, assignment and compound assignment. Precedence 16: throw Precedence 17: comma
How is a bitwise copy created in c plus plus?
You could just use memcpy(3), using sizeof() to get the object size.
What is the use of bitwise operator in c plus plus?
They perform bitwise operations like AND (&), OR (|), XOR (^) and NOT (~).
What are logical classes in c plus plus?
There is no such thing. Logic is bitwise operation, not a data type.
How do you swap two numbers with bitwise operator in c plus plus?
// Note: ^ is the XOR operator a = a ^ b b = b ^ a a = a ^ b
What is use of l in c language?
Bitwise OR.
What is c plus c plus c plus c plus c?
c + c + c + c + c = 5 * c.
What are the conditions to swap in c plus plus without temporary?
You can swap two integers without temporary storage by bitwise exclusive-or'ing them in a specific sequence...a ^= b;b ^= a;a ^= b;
How do you concatinate two files in c plus plus?
Copy the first file then append the second file to the copy.
What are Bit Manipulations in C programming?
in C you can manipulate the individual bits of a data item. << leftwise shift >> rightwise shift & bitwise AND | bitwise OR ~ bitwise complement (flips all bits) I can't go intoa tutorial here in how to use these, but google it - i just did and there's tons of info out there.

strcpy
Users can use a shortcut such as CTRL plus C for operations they perform frequently?

What command is the control key plus c?
Copy the selected text (or object).
