Instruction in memory has two parts: opcode and operands. The operands are subjects of the operation, such as data values, registers, or memory addresses. Due to variety of opcodes and operands, instructions may occupy different sizes of bytes in memory
Answer:
Computer scientists began building rudimentary games and simulations on mainframe computers in the 1950s and 1960s, with MIT's Spacewar! in 1962 being one of the first such games to be played with a video display. The first consumer-ready video game hardware arrived in the early 1970s, with the Magnavox Odyssey, the first home video game system, and the first arcade video games from Atari, Computer Space and Pong, the latter of which was later transformed into a home console version. Pong's success in arcades and at home prompted numerous firms to create clones of the game, resulting in a market contraction in 1978 owing to oversaturation and a lack of innovation.
Answer:
Following are the program in the C++ Programming Language.
//set header file
#include <iostream>
//set namespace
using namespace std;
//define class
class format
{
//set access modifier
public:
//set string type variable
string res;
//define function
void names(string first_name, string last_name)
{
//set if-else if condition to check following conditions
if(first_name.length()>0 && last_name.length()>0)
{
res="Name: "+last_name+", "+first_name;
}
else if(first_name.length()>0 and last_name.length()==0)
{
res="Name: "+first_name;
}
else if(first_name.length()==0 and last_name.length()==0)
{
res="";
}
}
//define function to print result
void out(){
cout<<res<<endl;
}
};
//define main method
int main() {
//set objects of the class
format ob,ob1,ob2;
//call functions through 1st object
ob.names("John","Morris");
ob.out();
//call functions through 2nd object
ob1.names("Jhon","");
ob1.out();
//call functions through 3rd object
ob2.names("", "");
ob2.out();
}
<u>Output</u>:
Name: Morris, John
Name: Jhon
Explanation:
<u>Following are the description of the program</u>:
- Define class "format" and inside the class we define two void data type function.
- Define void data type function "names()" and pass two string data type arguments in its parameter "first_name" and "last_name" then, set the if-else conditional statement to check that if the variable 'first_name' is greater than 0 and 'last_name' is also greater than 0 then, the string "Name" and the following variables added to the variable "res". Then, set else if to check that if the variable 'first_name' is greater than 0 and 'last_name' is equal to 0 then, the string "Name" and the following variable "first_name" added to the variable "res".
- Define void data type function "out()" to print the results of the variable "res".
- Finally, we define main method to pass values and call that functions.
Execute this assignment from Scratch in the following way
Explanation:
1.For each thread, first Scratch sets the 'active thread' to that thread. Then, it executes each block one by one in the stack for the active thread. It will execute the entire stack all in one go if it can.
2.The Hide block is a Looks block and a Stack block. If the block's sprite is shown, it will hide the sprite — if the sprite is already hidden, nothing happens. This block is one of the simplest and most commonly used Looks blocks.
3.Scratch is used in many different settings: schools, museums, libraries, community centers, and homes.
4.Mitch Resnik, the creator of the super-simple Scratch programming language and head of the Lifelong Kindergarten group at the MIT Media Lab, gave a TEDx talk about the value of coding and computer literacy in early education.
