Calculation Output 4

Problem Description

Compute the result of $7$ divided by $2$ and print it.

Input Format

This problem has no input.

Output Format

Print one line containing a single real number: the result of $7 \div 2$.

Hint

• The problem has just one trap: in C++, 7 / 2 is not 3.5. Why? Think about the type of the result when two int values are divided.
• To keep the fractional part in a division, at least one operand must be written in decimal form.
• No fixed number of decimal places is required here; printing the result directly gives 3.5.
