How is scientific notation represented in C++?

In C++, scientific notation is represented using the format that involves the base followed by the letter 'e' or 'E' and then the exponent. This format effectively allows programmers to work with very large or very small numbers in a compact way.

For example, the number 6.02 x 10^23 could be represented as 6.02e23 or 6.02E23 in C++. This representation makes it clear that the number is a floating-point value multiplied by ten raised to the power of the exponent.

The use of 'e' or 'E' is standard in many programming languages for denoting scientific notation, facilitating easy reading and writing of large numerical values. Recognizing this format is essential for understanding how to work with floating-point literals in C++. In contrast, the other options might reference various mathematical concepts or formats that do not align with the C++ implementation for scientific notation.
