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 compiler replaces the function call with the actual code of the inline function, i...
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. int x=45; int *ptr=&x; It should be noted that the data type of the variable and the pointer...

The ternary operator is used to execute code based on the result of a binary condition. It takes in a binary condition as input, which makes it similar to an 'if-else' control flow block. It also, however, returns a value, behaving similar to a function
Space after an identifier, but not after a potential operator, implies a function call using command syntax. For example: ls ./d Spaces on both sides of a potential operator, or no spaces on either side of the operator, imply an operation on variables. For example, these statements are eq...
Line 4:Another thing that always appear in a C++ program isint main(). This is called afunction. Any code inside its curly brackets{}will be executed. Line 5:cout(pronounced "see-out") is anobjectused together with theinsertion operator(<<) to output/print text. In our example, it ...
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...

Operator Meaning AND In order for the entire conditional expression to be true, the comparisons on the left and right side of the AND must both be true. If either of them is false, then the entire statement is false. OR For the entire conditional expression to be true, at least one of...
