What is the meaning of exponents?
An exponent is a number or letter written above and to the right of a mathematical expression called the base. It indicates that the base is to be raised to a certain power. x is the base and n is the exponent or power.
What does constant mean in graphs?
A constant function is a function whose range consists of a single element. That is, the output value of the function at any input value in its domain is the same, independent of the input. The graph of a constant function is a horizontal line, that is, a line with slope 0.
What is the right way to declare constant in C?
const datatype variable = value ; So to declared the constant we used const int var=10; is the correct way to declared the constant in the c programming language .
Where we can define constant in C?
Variables can be declared as constants by using the “const” keyword before the datatype of the variable. The constant variables can be initialized once only. The default value of constant variables are zero. A program that demonstrates the declaration of constant variables in C using const keyword is given as follows.
What is const in C?
In C++, you can use the const keyword instead of the #define preprocessor directive to define constant values. Values defined with const are subject to type checking, and can be used in place of constant expressions. In C++, you can specify the size of an array with a const variable as follows: C++ Copy.
How the constants are declared?
You use the Const statement to declare a constant and set its value. By declaring a constant, you assign a meaningful name to a value. Once a constant is declared, it cannot be modified or assigned a new value. You declare a constant within a procedure or in the declarations section of a module, class, or structure.
What value is EOF?
What will happen when the structure is declared?
What will happen when the structure is declared? Explanation: While the structure is declared, it will not be initialized, So it will not allocate any memory. Explanation: The structure declaration with open and close braces and with a semicolon is also called structure specifier.
What is the difference between union and structure in C?
A structure is a user-defined data type available in C that allows to combining data items of different kinds. Structures are used to represent a record. A union is a special data type available in C that allows storing different data types in the same memory location.
Which is more effective while calling the function?
Which is more effective while calling the functions? Explanation: In the call by reference, it will just passes the reference of the memory addresses of passed values rather than copying the value to new memories which reduces the overall time and memory use. 6.
Who is an operator?
The definition of an operator is someone who controls a machine, or the manager or owner of a business. An example of an operator is a person who controls a telephone switchboard. An example of an operator is a person who runs a pest control business.
Which operator has the highest priority?
The exponential operator has the highest priority. Operators + and – can also be used as unary operators, meaning that they only need one operand. For example, -A and +X.
Why is it called ternary operator?
The name ternary refers to the fact that the operator takes three operands. The condition is a boolean expression that evaluates to either true or false . The ternary operator is an expression (like price + 20 for example), which means that once executed, it has a value.
