Answer:

Logic error.

Explanation:

When a logic error occurs sometimes it becomes difficult to locate the error in the code.So to locate the error dummy print used to see which loop,if,else,switch case etc. is executing or not.

for example:-

for(int i=0;i<45;i++)

{

if(i!=1)

{

continue;

}

cout<<i<<endl;

}

we wanted the loop to print all value of i except 1 but it is printing only 1.We can use dummy print statement for this code in if condition.for(int i=0;i<45;i++)

{cout<<"Loop"<<endl;

if(i!=1)

{

cout<<"Printing"<<endl;

continue;

}

cout<<i<<endl;

}

We see that the loop is printed 45 times and printing 44 times.We found that the condition in if statement is wrong.It hould be '==' instead of '!='.

insens350 [35]

The answers are;

highlights job roles and skills rather than positions

contains data relevant to the position for which you are applying

based on data obtained from a career portfolio

Skills and achievements in a functional resume are the focal points. This is the reason why a functional resume is also known as the skills-based resume. This resume is not commonly used. However, job seekers who are changing careers or have gaps in their employment history typically use a functional resume to emphasize their capabilities. On the contrast, a traditional chronological resume shows a timeline of reverse work experience with brief explanations of each job.

Use the loop invariant (I) to show that the code below correctly computes the product of all elements in an array A of n integer

NeTakaya

Answer:

Given Loop Variant P = a[0], a[1] ... a[i]

It is product of n terms in array

Explanation:

The Basic Step: i = 0, loop invariant p=a[0], it is true because of 'p' initialized as a[0].

Induction Step: Assume that for i = n - 3, loop invariant p is product of a[0], a[1], a[2] .... a[n - 3].

So, after that multiply a[n - 2] with p, i.e P = a[0], a[1], a[2] .... a[n - 3].a[n - 2].

After execution of while loop, loop variant p becomes: P = a[0], a[1], a[2] .... a[n -3].a[n -2].

for the case i = n-2, invariant p is product of a[0], a[1], a[2] .... a[n-3].a[n-2]. It is the product of (n-1) terms. In while loop, incrementing the value of i, so i=n-1

And multiply a[n-1] with p, i.e P = a[0].a[1].a[2].... a[n-2].

a[n-1]. i.e. P=P.a[n-1]

By the assumption for i=n-3 loop invariant is true, therefore for i=n-2 also it is true.

By induction method proved that for all n > = 1 Code will return product of n array elements.

While loop check the condition i < n - 1. therefore the conditional statement is n - i > 1

If i = n , n - i = 0 , it will violate condition of while loop, so, the while loop will terminate at i = n at this time loop invariant P = a[0].a[1].a[2]....a[n-2].a[n-1]

Write a program whose input is two integers and whose output is the two integers swapped. Place the values in an array, where x

Aliun [14]

Answer:

import java.util.Arrays;

public class swap{

public static void main(String []args){

int [] arr = {2,4};

swapValues(arr);

}

public static void swapValues(int[] values){

int temp;

System.out.println(Arrays.toString(values));

temp=values[0];

values[0]=values[1];

values[1] =temp;

System.out.println(Arrays.toString(values));

}

}

Explanation:

In the program above, we created the method swapValues that receives an array of integers as parameters. in the method definition, we created a temp variable that is used to swapp the element at index 0 and index 1. Java's Arrays.to string method is used to print the array before and after the swap.
