Explanation of code: In each line, we are using different types of operators and related operands.
In the 1st line:
“=” acts as an assignment operator and “m”, “n”, 34.76 and 3.6 are variables and constants.
Similarly in the 2nd line:
“=” acts as an assignment operator and “a”, “b”, 1 and 4 are variables and constants.
In the 3rd line:
“=” and “*” acts as an assignment operator and binary operator respectively and “m”, “n” and “r” are
operands.
In the 4th line:
“=” and “-” acts as an assignment operator and binary operator respectively and “a”, “b” and “c” are
operands.
In the above example, m*n and b-a are Arithmetic Expression and r = m*n and c = b-a is said to be Arithmetic
Statement.
Arithmetic Expression: Any meaningful expression containing identifiers, literals, and arithmetical operators and
producing a result is called an Arithmetic Expression.
Example: a*b, 2*(l + b)
Arithmetic Statement: When the expression is assigned to a variable, then it is called Arithmetic Statement.
Example: c=a*b, p=2*(l + b)
