2min speech on can teachers be replace by technology​
elena-s [515]

Answer:

The boom of online courses, where anyone can learn from the comfort of one’s own home or office at their own chosen time is the main cause. When online courses made their foray a decade ago, the same question of technology replacing teachers in schools emerged as a major argument. However, if we ask you today whether calculators can replace mathematics teachers at school, what would you say? Sounds weird, right! Do you think calculators which are also a kind of a technological advancement only, are capable enough of themselves, so as to replace the teachers? The answer is obvious. It’s an obvious No!

Flesh out the body of the print_seconds function so that it prints the total amount of seconds given the hours, minutes, and sec
fiasKO [112]

Answer:

Step by step explanation along with code and output is provided below

Explanation:

#include<iostream>

using namespace std;

// print_seconds function that takes three input arguments hours, mints, and seconds. There are 60*60=3600 seconds in one hour and 60 seconds in a minute. Total seconds will be addition of these three  

void print_seconds(int hours, int mints, int seconds)

{

   int total_seconds= hours*3600 + mints*60 + seconds;

   cout<<"Total seconds are: "<<total_seconds<<endl;

}

// test code

// user inputs hours, minutes and seconds and can also leave any of them by  entering 0 that will not effect the program. Then function print_seconds is called to calculate and print the total seconds.

int main()

{

   int h,m,s;

   cout<<"enter hours if any or enter 0"<<endl;

   cin>>h;

   cout<<"enter mints if any or enter 0"<<endl;

   cin>>m;

   cout<<"enter seconds if any or enter 0"<<endl;

   cin>>s;

   print_seconds(h,m,s);

  return 0;

}

Output:

enter hours if any or enter 0

2

enter mints if any or enter 0

25

enter seconds if any or enter 0

10

Total seconds are: 8710

  {

      scanf("%d", &A[i]); //read array from stdin

  }

  printf("%s\n",ArrayChallenge(A)); //ccall function and print answer

What two features distinguished Windows 2.0 from Windows 1.0?
zysi [14]
This question is a bit ambiguous as there were a few features that were added and any could be perceived as distinguishing depending on what you look for in your OS. I do believe this is in reference to the Wikipedia article on Windows 2.0 though as the first two listed features make note of Windows 1.0 specifically, therefore:

Windows 2.0 allowed windows to overlap, Windows 1.0 could not do this.

Windows 2.0 introduced new and more complex keyboard shortcuts and terminology such as "Minimize" and "Maximize" vs. Window 1.0's "Iconize" and "Zoom"
