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

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
