Question
int x = 4;
if (x < 0) {
x *= -1;
}
What does the code snippet do?
2.) Given the following function prototype:
public static void Display(int[] ary)
Select the correct choice below.
3.) Large complex problems are best solved by __________ .
4.)
Select the choice that initializes all elements in the array to -1.
a.) int[][] ary = new int[N][N];
for (int i = 0; i < N; i++)
{
ary[i][j] = -1;
}
b.) int[][] ary = new int[N][N];
for (int i = 0; i < N; i++) {
for (int j = 0; j < N; j++) {
ary[i][j] = -1;
}}
c.) int[][] ary = new int[N][N];
for (int i = 0; i < N; i++) {
for (int j = 0; j < N; j++) {
ary[i] = -1;
}}
a. the code snippet creates the absolute value of xExplanation / Answer
Question 1:
Answer: b. the code snippet cannot work since x is greater than 0.
x values is 4 which is greater then zero so it skips the if condition
Question 2:
Answer:
The argument passed to the function is an integer array.
Question 3:
Answer:
dividing the problem into functions
yes convert the repeated code part in function and call when ever in use reduces the large code problem
Question 4:
Answer:
b.) int[][] ary = new int[N][N];
for (int i = 0; i < N; i++) {
for (int j = 0; j < N; j++) {
ary[i][j] = -1;
}}
c.The argument passed to the function is an integer array.
