In C++, the easiest way is probably to use a std::bitset as : Example Output

Sets c as the stream’s fill character.   Behaves as if member fill were called with c as argument on the stream on which it is inserted as a manipulator (it can be inserted...

i++ shows that the value of i is post incremented after operation, ++i shows that its pre incremented before operation. Example Output

1. Proper pointer initialization One common way is to assign the pointer an address to a previously defined variable. For example: Or, equivalently, Other common ways include assigning the pointer the address of memory...

Segmentation Fault, bus error or access violation is generally an attempt to access memory that the CPU cannot physically address. It occurs when the hardware notifies an operating system about a memory access violation....

To allow programs to be broken up into logical parts, C++ supports what is commonly known as separate compilation. Separate compilation lets us compose a program from several files. To support separate compilation. Designing...

A typedef lets us define a synonym for a type. Example Output A typedef definition begins with the keyword typedef, followed by the data type and identifier. The identifier, or typedef name, does not...

A const reference is a reference that may refer to a const object: Example We can read from but not write to refVal. Thus, any assignment to refVal is illegal. This restriction should make...

We can define multiple references in a single type definition. Each identifier that is a reference must be preceded by the & symbol: Example Output

Because a reference is just another name for the object to which it is bound, all operations on a reference are actually operations on the underlying object to which the reference is bound. Example...

A reference serves as an alternative name for an object. In real-world programs, references are primarily used as formal parameters to functions.   A reference is a compound type that is defined by preceding...

A constant variable is defined by const kwyword and can not be modified later. Example : Example

A global variable’s scope is throughout the program in which the variable is declared, from any where, in any function we can modify the variable and local variables are limited to the block only...

Variables can be initialized and defines anywhere in the program. Following example will demontrate how to define variables and declare variables. Example Output

C++ reserves a set of words for use within the language as keywords. Keywords may not be used as program identifiers. following Table lists the complete set of C++ keywords. asm do if return...

Some characters are nonprintable. A nonprintable character is a character for which there is no visible image, such as backspace or a control character. Other characters have special meaning in the language, such as...
