8 0

Answer:

Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope in 1590.

Explanation:

A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses. Eeuwenhoek observed animal and plant tissue, human sperm and blood cells, minerals, fossils, and many other things that had never been seen before on a microscopic scale. He presented his findings to the Royal Society in London, where Robert Hooke was also making remarkable discoveries with a microscope.

Write a C++ program to exchange values of two variables using function exchange().
Shkiper50 [21]

Answer:

#include<iostream>

using namespace std;

//create the exchange function

void exchange(int a, int b){

   int temp;  //initialize temporary

   //swap the variables value

   temp=a;

   a=b;

   b=temp;

   //print the output after exchange

   cout<<"a is: "<<a<<endl;

   cout<<"b is: "<<b<<endl;

}

//main function program start from here

int main(){

  //initialization

  int a=3, b=6;

  exchange(a,b);  //calling the function

  return 0;

}

Explanation:

Create the function exchange with two integer parameter which takes the value from the calling function.

and then declare the third variable temp with is used for swapping the value between two variables.

first store the value of 'a' in the temp and then assign the 'b' value to 'a' and then, assign the temp value to b.

for example;

a=2, b=9

temp=2;

a=9;

b=2;

So, the values are swap.  

and then print the swap values.

Create the main function and define the input a and b with values.

Then, calling the exchange function with two arguments.

I can't find the errors! Could anyone help me please?!

The only syntax error I saw was that the re pattern should have been double quoted.

Other non-syntax errors are: the import statement doesn't have a valid module name. It should be "import re" . Since tutorGroup is double quoted in the re.match(), it becomes a string, not the variable from the input() function.

THIS IS MY PERSONAL OPINION:
The world is indeed changing very fast, and the future brings new possibilities and new realities. I foresee that humans will thrive for another 50 years, until the global warming situation reaches its limits. The people in the future I think will not have any ( maybe rarely) social interactions, maybe we will go to the moon etc. but i still strongly believe that the end of humanity is decades close.
I hope this helps you :)
