Developed the first compiler and conducted work that led to the development of COBOL ?
zimovet [89]

Answer:

Grace Hopper.

Explanation:

Grace Hopper was a US Naval Rear Admiral and an American computer scientist who was born on the 9th of December, 1906 in New York city, United States of America. She worked on the first commercial computer known as universal automatic computer (UNIVAC), after the second World War II.

In 1953 at the Remington Rand, Grace Hopper invented the first high-level programming language for UNIVAC 1 by using words and expressions.

Additionally, the high-level programming language known as FLOW-MATIC that she invented in 1953 paved the way for the development of common business-oriented language (COBOL).

Hence, Grace Hopper developed the first compiler and conducted work that led to the development of COBOL.

What are the advantages and disadvantages of using wireless communications? What are the advantages and disadvantages of using w
Nimfa-mama [501]

Answer:

<u>Advantages of wireless communication:-</u>

  • Flexibility in transferring the message through communication for which the sender and receiver can be in any place.
  • Speed of the communication is accurate and fast
  • Due to no wiring , the cost of the wireless communication is less.

<u>Disadvantages of wireless communication:-</u>

  • The security is less as the data can be accessed by unauthorized sources at times.
  • The setting up of wireless communication complex and expensive.

<u>Advantages of wired communication:-</u>

  • Simple configuration
  • Higher bandwidth is present in the cable
  • High reliability

<u>Disadvantages of wired communication:-</u>

  • Mobility is present for communication
  • Installation requires lot of time due to cabling
  • Requires extra devices for covering large areas for communication

Wireless communication is more preferable than wired communication in the conditions like communication connection that should face low damage and longer life which is not present in cable connection as they break or get disrupted.The flexibility of moving while communication is required by most people so, they use wireless communication .

We informally define the term corresponding element as follows: The first element in an array and the last element of the array
yanalaym [24]

The corresponding element in an array can be written as follows.

The given array is arr[len] whose size is given by integer variable len. We take another integer variable k.

Corresponding element for arr[k] = arr[len-1-k]

This applies for all expressions of k beginning from 0 upto half the size of len, i.e., len/2.

For element, arr[0], the corresponding element is arr[10-1-0] = arr[9].

The above expression is valid if the sum of index of both element and its corresponding element adds upto the index of the last element of the array.

Example: k + (len – 1 - k)  

= k + len – 1 - k

= len – 1

= index of the last element of the array

The number of elements that an array can hold is one more than the index of the last element of the array.

Suppose an array of 10 elements is given. The above expression holds true since first element of the array is always written as arr[0] and last element will be written as arr[9] for an array of 10 elements.

This is illustrated below.

The c++ program to display the element and its corresponding element along with their index is shown below.

#include <iostream>

using namespace std;

int main() {    

   int len=10, arr[len],k;    

   for(k=0; k<len; k++)

   {

       // elements are initialized to twice their index

       arr[k] = k*2;

   }

   cout<<"Element "<<" Index "<<"\t"<<" Corresponding "<<" Index"<<endl;

   for(k=0; k<len/2; k++)

   {

       cout<<arr[k]<<"\t"<<"\t"<<"\t"<<k<<"\t"<<"\t"<<"\t"<<arr[len-1-k]<<"\t"<<"\t"<<len-1-k<<endl;

   }

}

OUTPUT

Element Index    Corresponding   Index

0  0   18  9

2  1   16  8

4  2   14  7

6  3   12  6

8  4   10  5

 

The above program initializes all the elements of the array to twice the value of their corresponding index. Following this, the element, its index, the corresponding element and its index is displayed.

All the above is achieved using for loop. The size of the array and its elements can be changed.

The expression for the corresponding element is thus explained.
