What is the correct way to represent hexadecimal values in C++?

Solution (By Examveda Team)

Computers use different number systems. Decimal (base-10) is what we use every day. Hexadecimal (base-16) is useful for representing colors, memory addresses, and other things.

In C++, we use a special prefix to tell the compiler that a number is in hexadecimal.

Option A is incorrect because suffixes (things added to the end) aren't used for this purpose in C++.

Option B is also wrong. A prefix means something that comes at the beginning.

Option C is close, but not quite right. It's a bit of an older style.

Option D, "Prefix with 0x", is the correct answer. The '0x' prefix tells the compiler that the following number is in hexadecimal. For example: 0x1A represents the hexadecimal number 1A, which is equivalent to 26 in decimal.

Therefore, the correct way to represent hexadecimal values in C++ is by prefixing them with 0x.
