The following program segment should output the number 9 int

The following program segment should output the number 9. int x = 4; cout

Solution

the code is needed to modify the value 4 to 5 inorder to produce the output as 9;

because initially the value of x is declared as 4 and in the cout command the x is post incremented ( x++) it means that the value of x is 4 for the first time and then the value of x is incremented to 5 for the second time but here the value of x is printed for the first time then the value ( x++ + 4 ) is 4 + 4 =8 ; so it will produce the output as 8 . inorder to get the output as 9 we need to modify the value 4 as 5 then (x++ +5) = 4+5 = 9;

the following is the code change inorder to get the output as 9;

int x=4;

cout << (x++ +5);

=========================================

also we can get the output as 9 by changing the code as below:

int x=4;

cout << (++x + 4);

which means the x is pre incremented by 1 then the value will become the 5 +4 = 9;
