Question

What is difference between a Compiler and Just In Time Compiler ?

Answer 1

A JIT compiler runs after the program has started and compiles the code (usually bytecode or some kind of VM instructions) on the fly (or just-in-time, as it's called) into a form that's usually faster, typically the host CPU's native instruction set. A JIT has access to dynamic runtime information whereas a standard compiler doesn't and can make better optimizations like inlining functions that are used frequently.

This is in contrast to a traditional compiler that compiles all the code to machine language before the program is first run.

what are inling functions can you please elaborate in context of your answer with an example ?

#define square(x) x*x int main() {   int x = 36/square(6); // will be expended as 36/6*6   printf("%d", x);   return 0; } // Output: 36

If we use inline functions, we get the expected output using inline functions.

inline int square(int x) { return x*x; } int main() {   int x = 36/square(6);   printf("%d", x);   return 0; } // Output: 1

okay thank you so much sir
