Question

Write the output of the following program part:
int c= 10;
for(int j = 1; j <= 5; j++, c++)
{
if (c++> 2 && ++c <15)
System.out.println(c * 2);
}
Please explain how the output will come??​

Answer 1

Required Answer:-

Given C∅de:

int c=10;

for(int j=1;j<=5;j++,c++) {

if(c++>2&&++c<15)

System.out.println(c*2);

}

To Find:

• Output (Java)

Solution:

Initially,

→ c = 10

→ j = 1

When j = 1:

→ j<=5 is true.

→ Loop will execute.

c++ > 2 && ++c < 15

= 10 > 2 && ++c < 15

= true && ++c < 15 (c becomes 11, post-increment)

= true && 12 < 15 (c becomes 12, pre-increment)

= true && true

= true

As the condition is true,

→ If block will execute.

→ c * 2 = 12 * 2 = 24

Output: 24

★ c and j are incremented.

→ c = 13, j = 2

When j = 2:

→ j<=5 is true.

→ Loop will execute.

→ c++ > 2 && ++c < 15

= 13 > 2 && ++c < 15 (c = 13, post-increment)

= true && ++c < 15 (c becomes 14)

= true && 15 < 15 (c becomes 15, pre-increment)

= true && false

= false

From now, condition is always false. So, no output will be shown when j = 3,4,5

Final Output: 24

Output:

• 24
