What will the following programs print on the screen?

A)

#include <iostream>
using namespace std;
int main()
{
    int freeze = 32, boil = 212;
    freeze = 0;
    boil = 100;
    cout << freeze << endl << boil << endl;
    return 0;
}

B)

#include <iostream>
using namespace std;
int main()
{
    int x = 0, y = 2;
    x = y * 4;
    cout << x << endl << y << endl;
    return 0;
}

C)

#include <iostream>
using namespace std;
int main()
{
    cout << "I am the incredible";
    cout << "computing\nmachine";
    cout << "\nand I will\namaze\n";
    cout << "you.\n";
    return 0;
}

(A)

$\text{\textcolor{#19804f}{int}}$ freeze= 32, boil = 212;

$\text{\textcolor{#c34632}{Here, freeze is assigned value 32 and boil is assigned value 212}}$

freeze = 0; $\text{\textcolor{#c34632}{value assigned to freeze is updated to 0}}$

boil = 100 ; $\text{\textcolor{#c34632}{value assigned to boil is updated to 100}}$

$\text{\textcolor{#4257b2}{cout}}$ $<<$freeze$<<$ endl $<<$ boil $<<$ endl ;

The output for (A):

0

100

(B)

$\text{\textcolor{#19804f}{int}}$ x=0, y= 2;

$\text{\textcolor{#c34632}{Here, x is assigned value 0 and y is assigned value 2}}$

$x= y\times 4$; $\text{\textcolor{#c34632}{value assigned to x is updated to $y\times 4=2\times 4=8$}}$

$\text{\textcolor{#4257b2}{cout}}$ $<<$x$<<$ endl $<<$ y$<<$ endl ;

The output for (B):

8

2

(C) Since $\text{\textbackslash}$ n is newline escape character it jumps to a new line.

The output for (C):

I am the incrediblecomputing

machine

and I will

amaze

you.

A) This program will print latest values of freeze and boil in separate lines.

That is

0

100

B) This program will print following

8

2

C) This program will print following

I am incrediblecomputing

machine

and I will

amaze

you.
