Assume that you have an ArrayList variable named a containing 4 elements, and an object named element that is the correct type t

jonny [76]

Answer:

Option (4) is the correct answer.

Explanation:

In Java programming language ,array collection starts from 0 index location and ends in a size-1 index location. So to access the last elements the user needs to use a[Size-1] statement. so to modify the value of the last location of the array the user needs to use "a[size-1]= element;".

But when the user wants to add some new value to the end of the array list collection then he needs to use the statement--

a.add(element); //where add is a function, element is a value and a is a array list object.

Another option is invalid because--

Option 1 is not the correct because "a[3]=element;" modify the value of the 3rd element of the array.
Option 2 gives a compile-time error because add functions bracts are not closed.
Option 3 gives the error because a[4] gives the location of the 5th element of the array but the above question says that a is defined with 4 elements.

Write a program that accepts a number as input, and prints just the decimal portion.

Olegator [25]

Answer:

There are 2 ways to do extract the decimal part: 

Explanation:

First method using number

int main() {

double num = 23.345;

int intpart = (int)num;

double decpart = num - intpart;

printf(""Num = %f, intpart = %d, decpart = %f\n"", num, intpart, decpart);

}

Second method using string:

#include <stdlib.h>

int main()

{

char* inStr = ""123.4567"";

char* endptr;

char* loc = strchr(inStr, '.');

long mantissa = strtod(loc+1, endptr);

long whole = strtod(inStr, endptr);

printf(""whole: %d \n"", whole);

printf(""mantissa: %d"", mantissa);

}

2.Consider the following algorithm and A is a 2-D array of size ???? × ????: int any_equal(int n, int A[][]) { int i, j, k, m; f

Elis [28]

Answer:

(a) What is the best case time complexity of the algorithm (assuming n > 1)?

Answer: O(1)

(b) What is the worst case time complexity of the algorithm?

Answer: O(n^4)

Explanation:

(a) In the best case, the if condition will be true, the program will only run once and return so complexity of the algorithm is O(1) .

(b) In the worst case, the program will run n^4 times so complexity of the algorithm is O(n^4).
