What is 1ul in C?
So 1ul is an unsigned long version of 1. By default integer constants are (signed) ints. For long long constants, use ll, e.g., the unsigned long long constant 0xdeadbeef01234567ull.
How many bits is a long in C?
How do Bitwise operators work in C?
What is data type in Python?
Data types are the classification or categorization of knowledge items. It represents the type useful that tells what operations are often performed on specific data. Since everything is an object in Python programming, data types are classes and variables are instances (object) of those classes.
What is INTEGER data type in C++?
Integer: The keyword used for integer data types is int. Integers typically require 4 bytes of memory space and range from -2147483648 to 2147483647. Character: Character data type is used for storing characters. The keyword used for the character data type is char.
How do I use XOR in C++?
The ^ (bitwise XOR) in C or C++ takes two numbers as operands and does XOR on every bit of two numbers. The result of XOR is 1 if the two bits are different. The << (left shift) in C or C++ takes two numbers, left shifts the bits of the first operand, the second operand decides the number of places to shift.
What is data type long in C?
Longer integers: long
The long data type stores integers like int , but gives a wider range of values at the cost of taking more memory. Long stores at least 32 bits, giving it a range of -2,147,483,648 to 2,147,483,647. Alternatively, use unsigned long for a range of 0 to 4,294,967,295.
What is bit level programming?
Bitwise Operators are used for manipulating data at the bit level, also called bit level programming. Bitwise operates on one or more bit patterns or binary numerals at the level of their individual bits. They are used in numerical computations to make the calculation process faster.
How do you write or in C++?
Operator keyword for ||
C++ specifies or as an alternative spelling for || . In C, the alternative spelling is provided as a macro in the <iso646. h> header. In C++, the alternative spelling is a keyword; use of <iso646.
How do you make a set in Python?
Creating Python Sets
A set is created by placing all the items (elements) inside curly braces {} , separated by comma, or by using the built-in set() function. It can have any number of items and they may be of different types (integer, float, tuple, string etc.).
How do you use long in Python?
Type int(x) to convert x to a plain integer. Type long(x) to convert x to a long integer. Type float(x) to convert x to a floating-point number.
How do I use pointers in CPP?
- Define a pointer variable.
- Assigning the address of a variable to a pointer using unary operator (&) which returns the address of that variable.
- Accessing the value stored in the address using unary operator (*) which returns the value of the variable located at the address specified by its operand.

What is keyword in C Plus Plus?
Keywords are those words whose meaning is already defined by Compiler. These keywords cannot be used as an identifier. Note that keywords are the collection of reserved words and predefined identifiers. Predefined identifiers are identifiers that are defined by the compiler but can be changed in meaning by the user.
How do I input binary in C++?
- if s[j] is same as ‘1’, then − (increase cnt by 1)
- Otherwise. (decrease cnt by 1)
- if cnt is same as 0, then − insert “1” + makeLargestSpecial(substring of s from index i + 1 to j – i – 1) at the end of v. i := j + 1.

How do I convert a string to an int in C++?
One effective way to convert a string object into a numeral int is to use the stoi() function. This method is commonly used for newer versions of C++, with is being introduced with C++11. It takes as input a string value and returns as output the integer version of it.
What is the size of char variable in Java?
char: The char data type is a single 16-bit Unicode character. It has a minimum value of ‘u0000’ (or 0) and a maximum value of ‘uffff’ (or 65,535 inclusive).
What a variable is?
A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables.
What does >> mean in C?
Bitwise Right shift operator >> is used to shift the binary sequence to right side by specified position.
What is header file in C?
A header file is a file with extension . h which contains C function declarations and macro definitions to be shared between several source files. There are two types of header files: the files that the programmer writes and the files that comes with your compiler.
How do you print something in C++?
