Chapter 5, Problem 1MC
Program Description Answer
The println statement in the given
Hence, the correct answer is option “A”.
Expert Solution & Answer
Explanation of Solution
Increment operator “++”:
The increment operator is used to increment or increase the value of the variable by “1”.
Example:
/*the variable val is increased by 1 with a postfix representation */
val++;
/*the variable val is increased by 1 with a prefix representation */
++val;
In the given program segment, the variable “x” is declared and initialized with the value “5”. In the println statement, post-increment operation is performed using the statement “x++”. As per postfix mode, the value of the variable “x” is printed and then the value is incremented. Therefore, the value of “x”, which is “5” is printed using the println statement and then the value of “x” is incremented.
Explanation for incorrect options:
b. 6:
The value of “x” is incremented to 6 after it is displayed.
Hence, the option “B” is wrong.
c. 0:
The value of “x” is initialized as 5, and then it is not modified as “0”.
Hence, the option “C” is wrong.

what will the following code segment print on the screen?
int a,x=23;
a=x+2;
system.out.printf("%d+%d\n",x,a);
A function declared int addition (int a and b) is capable of returning one value back to the main loop.
True
False
Given the following program segment:
int first = 3;
int second = 4;
int j;
for ( j = 1; j <= first; j++)
{
cout << second * j <<endl;
second= second + (j - 1);
}
cout << endl;
Your task is to write a while loop and a do ... while loop which will produce the same output.
