What does an assignment statement do give an example of an assignment statement?

An assignment statement gives a value to a variable. For example, the variable may be a simple name, or an indexed location in an array, or a field (instance variable) of an object, or a static field of a class; and. the expression must result in a value that is compatible with the type of the variable .

Which statement is known as the assignment statement?

In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct.

How to assign values to variables in C + + 17?

Q: C++ provides copy, direct, and list initialization, and copy assignment. Is there a direct or list assignment? No, C++ does not support a direct or list assignment syntax. When a variable is initialized with empty braces, value initialization takes place.

What is the result of integer division in C + + 11?

Integer division drops any fractions and returns an integer value. For example, 7 / 4 = 1 because the fractional portion of the result is dropped. Similarly, -7 / 4 = -1 because the fraction is dropped. Prior to C++11, integer division with a negative operand could round up or down. Thus -5 / 3 could result in -1 or -2.
