class OutPut { public static void main(String[] args) { int out = -15; for (int i = 0; i < 5; i++) { for (int j = 8; j > 4; j -= 2) { if (i <= j) { out += i + j; } else { out -= j - i; } } } System.out.println("out = " + out); } }
out = 155
out = -65
out = 75
Compilation Error
Correct Answer : C
Inside main, an integer variable out is declared and initialized to -15. Then comes a for loop with following conditions :
Initialization Condition : i = 0
Terminating Condition : i < 5
Increment Value : 1
Inside the above loop is another for loop with :
Initialization Condition : j = 8
Terminating Condition : j > 4
Increment Value : -2 (j -= 2)
Iteration 1 : i = 0 and j = 8. if(0 <= 8) returns true. So out = out + i + j = -15 + 0 + 8 = -7
Iteration 2 : i = 0 and j = 6. if(0 <= 6) returns true. So out = out + i + j = -7 + 0 + 6 = -1
Iteration 3 : i = 1 and j = 8. if(1 <= 8) returns true. So out = out + i + j = -1 + 1 + 8 = 8
Similarly other iterations. Finally out value will be 75 which is printed using display statement.
Output Is
