13B Lecture Notes - Inline Function, Compile Time
Document Summary
Inline functions are used to reduce the compilation time runtime and make programs faster. When a function is inline, the compiler places a copy of the specified function"s code at each point where the function is called at compile time. This helps reduce the overhead of control transfer, which can slow down the program. The syntax for using inline functions is to place the keyword "inline" before the return type of the function, followed by the function name, and then the parameters and function definition inside parentheses. Here"s an example of how to use an inline function in c++. In this example, we define a function called "triple" that takes in a number and returns the triple of that number. using namespace std; inline int triple(int num){ return num*3; Then, in the main logic, we can call this function using the function name and passing in a number.
