The function takes two integer variables a and b as input and returns their total which is calculated using the addition arithmetic operator. Note that when a call is made to this inline function sum(), the com
and the pointer “ptr” stores the address of the variable x. The & (addressof) operator is used to obtain the memory address of the variable x. A pointer can also be declared and initialized in a single step. It is called the pointer definition. ...

Then, we calculate the next term t3 in the series by adding t1 and t2 (using addition operator). After that, we update t1 to be the previous value of t2, and t2 to be the new value t3, preparing for the next iteration. After every iteration, we increment the value of i by 1 as...
