1015 . Relational Operators
Description
The relational operators in C programming language are shown in the table below. Of course the
last two are also known as equality operators.
These operators compare the value of the two operands it is working on (The value on its left and
the value on its right) and returns true or false (one or zero). For example value of 2 > 3 is
interpreted as “false” (As 2 is actually less than 3), value of 3 != 4 is interpreted as true and
value of 3 >= 3 is also interpreted as true. You have to find out this interpretation using a
program.
Input Format
The input file contains around 12000 line of input. Each line contains two integers a and b
separated by an operator “>”, “>=”, “<”, “<=”, “==” or “!=”. Input is terminated by
a line which contains an “E” instead of the operators. Note that there is also a space between any
operator and operand. You can assume (-10000 ≤ a, b ≤ 10000).
Output Format
For each line of input produce one line of output. This line contains the serial of output followed
by a string “true” or “false” (without the quotes) which denotes how the expression is interpreted
in C language. Look at the output for sample input for details.
Sample Input 1
4 < 4
4 <= 5
3 E 3
Sample Output 1
Case 2: false
Case 3: true
