Write a program that asks the user for three strings. Then, print out whether the first string concatenated to the second string

ipn [44]

Answer:

import java.util.Scanner;

public class num5 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter The First String");

String str1 = in.next();

System.out.println("Enter The Second String");

String str2 = in.next();

System.out.println("Enter The Third String");

String str3 = in.next();

String oneAndTwo = str1+str2;

if(str3.equals(oneAndTwo)){

System.out.println(str1+" + "+str2+" is equal to "+str3+"!");

}

else

System.out.println(str1+" + "+str2+" is not equal to "+str3+"!");

}

Explanation:

Implemented in Using Java Programming Language
Import Scanner Class to prompt and receive users' input
Create three string variables and store the three values entered by the user (str1, str2 and str3)
Concatenate str1 and str2 using the + operator and assign to a new variable
Use the if statement with Java's .equals() method to check for equality of the new string with the third string
Print the appropriate message if the equal or not

Which sequence best describes the evolution of computers?

SVETLANKA909090 [29]

Answer:

d. Mainframes came before minicomputers, which led to the development of microcomputers.

Explanation:

The first mainframe was introduced in 1951: The UNIVAC (UNIVersal Automatic Computer I): large computer systems, for general purpose, with hundreds of users (separated from the computer) and fast computations, typically deployed by large business, industry, and government organizations.

The minicomputers are another class of computers that start to evolve since the late of the 1950s and the beginning of 1960s (like LINC, PDP-1, among many others), and focused on to have a more direct contact with the user or programmer, and because of this, it is said that minicomputers were the first 'personal' computers. They were cheaper than mainframes and with less memory capacity.

Finally, the microcomputers appeared around the beginning of 1970s (Micral), and sometime later (Altair 8800, Apple II) and were firstly used by hobbyists and computers enthusiasts. The term microcomputers have been supplanted nowadays by 'personal computers'.
