A real number (floating-point number) in most programming languages follows this general format:

1. [digits] → Represents the integer part (optional).
2. [.digits] → Represents the fractional part (optional).
3. [(E|e)[(+|-)]digits] → Represents the exponent notation (optional).

This allows real numbers to be written in different forms, such as:

• 123.456 (Normal decimal representation)
• 0.789 (Starts with a decimal point)
• 123E4 (Scientific notation, equivalent to 123 × 10⁴)
• 3.14e-2 (Equivalent to 3.14 × 10⁻²)

Thus, option (A) [digits][.digits][(E|e)[(+|-)]digits] correctly represents the general syntax for real number representation.
