Why does the expression 5 / 2 in C result in 2 instead of 2.5?

ABecause both operands are integers, so integer division truncates the decimal

BBecause C automatically rounds all divisions down

CBecause 5 and 2 are treated as floats by default

DBecause the division operator always returns an integer

Step-by-Step Solution

Solution:

Step 1: Understand operand types in division
Both 5 and 2 are integers, so C performs integer division.
Step 2: Integer division truncates decimal part
Integer division drops the decimal, so 5 / 2 = 2, not 2.5.
Final Answer:
Because both operands are integers, so integer division truncates the decimal -> Option A
Quick Check:
