Q1. Answer)
In computer science, the inlining is the optimization of the manual or the compiler which is used to replace the function call location with the body of the function implementation. Thus inlining occurs during the compile-time and does not change the source code, and is then processed using the compiler. The inlining process has some effect on performance such as this can improve speed by it takes up more space.

Excess of inlining, however, will hurt the speed of the program execution as there is the inline code that will consume too much instruction cache and also much space. Thus the inline functions are somewhat little faster than the normal function calls as the calling of the function has some overhead which is saved in the inline calls.

Thus the inlining has benefits such as it eliminates the instructions which are required for the function calls, reduces the register spilling and also does not have to pass the references and then de-reference the calls when the call by reference is used.
