Explanation
The following code is a C program that demonstrates the use of various operators in the C programming language. These operators include arithmetic, modulo, relational, logical, bitwise, increment, decrement, assignment, and conditional operators.
At the start of the program, the user is prompted to enter two integer values separated by a space,
which are stored
in the variables d and m. The program then uses these values to
demonstrate the
functionality of each type of
operator.
Arithmetic operators include addition +, subtraction -, division
/, and
multiplication *. The result of each
operation is printed to the console with a description of the operator used.
The modulo operator % returns the remainder of the division of two values. The program
demonstrates
its use by
dividing d by m and printing the result.
Relational operators are used to compare two values. They include less than <,
greater than
>, less than or equal
to <=, greater than or equal to >=, not equal to !=,
and equal to
==. The program demonstrates the use
of each of these operators by comparing d and m and printing the result.
Assignment operators allow values to be assigned to variables. The program demonstrates the use of
the assignment
operator = by assigning the value of m to d.
Logical operators are used to perform logical operations on values. The program demonstrates the use
of the equal to
== operator, the logical and && operator, and the logical or
||
operator.
Bitwise operators are used to perform bitwise operations on values. The program demonstrates the use
of the logical
not ! operator, the bitwise and & operator, the bitwise or
|
operator, and the bitwise exclusive or ^
operator.
Increment and decrement operators are used to increase and decrease the value of a variable. The
program demonstrates
the use of the post-increment ++ and post-decrement -- operators.
Conditional operators allow for the execution of certain statements based on a condition. The program
demonstrates
the use of the conditional operator if a>b by comparing d and
m and printing the
value of d if d is
greater than m.
The program concludes by printing a summary of all the operations performed and the results.
