Write a program which increments from 0 to 20 and display results in Decimal on the console 2-b) Modify above program to increment from 0 to 20 and display results in Binary on the console

This program is written in C++

Comment are used to explain difficult lines

The first program that prints 0 to 20 (in decimal) starts here

#include<iostream>

int main()

{

//Print From 0 to 20

for(int i = 0;i<21;i++)

{

 std::cout<<i<<'\n';

}

}

The modified program to print 0 to 20 in hexadecimal starts here

#include<iostream>

using namespace std;

int main()

{

//Declare variables to use in conversion;

int tempvar, i=1,remain;

//Declare a char array of length 50 to hold result

char result[50];

//Print 0

cout<<"0"<<endl;

// Iterate from 1 to 20

for(int digit = 1; digit<21; digit++)

{

//Start Conversion Process

//Initialize tempvar to digit (1 to 20)

tempvar = digit;

while(tempvar!=0)

{

//Divide tempvar by 16 and get remainder

remain = tempvar%16;

if(remain<10)

{

 result[i++]=remain + 48;

}

else

{

 result[i++] = remain + 55;

}

//Get new value of tempvar by dividing it by 16

tempvar/=16;

}

//Print result

for(int l=i-1;l>0;l--)

{

cout<<result[l];

}

i=1;

cout<<endl;  

}

return 0;

}

//The Program Ends Here
