Study Notes
Functions
- Functions can be used to perform a specific task or set of tasks.
- Functions can be reused throughout a program, making it more efficient and organized.
Math Library Functions
- The math library includes functions to perform various mathematical operations, such as trigonometric functions.
- The expression
sin(x)returns the trigonometric sine ofx.
Exclusions in Math Library Functions
sqrtfunction is not included in the math library functions by default, but it can be declared separately.
Function Prototypes
- The function prototype
double mySqrt(int x);declares a function namedmySqrtthat takes an integerxas an argument and returns a double value.
