Question

Write a program that asks the user to input some letters to be vertically displayed. Put a zero at the end to signify the end of the letters to be printed much like the '#' in HW2B). You should skip white space, such as tabs, spaces or enters (see example 2). You should then print the input text vertically on the 10 character index 9 or in the middle) of each row, and the rest of the row should be filled with a random character chosen from {'0', '1','' or (space)}. There should be a total of 19 characters on each line (including the actual words, so it is in the center). You may assume they user always puts a zero at the end of their desired text. I suggest you break this program up into various parts (i.e. functions).

Answer 1

Answer:

C++ code is explained below

Explanation:

sequence.cpp

#include<iostream>

#include<cstdlib>

#include<ctime>

using namespace std;

char randomChar(){

   char arr[4] = {'0','1','.',' '};

   int index = rand()%4;

   return arr[index];

}

void printLine(char c, int spot, int len){

   for(int i=0;i<len;i++)

       cout<<randomChar();

   cout<<c;

   for(int i=0;i<len;i++){

       cout<<randomChar();

   }

   cout<<endl;

}

int main(){

   cout<<"What do you want printed vertically?"<<endl;

   string seq;

   getline(cin,seq);

   srand(time(NULL));

   char cleanedSeq[10000]; // to store sequence without spaces or tabs

   int i=0,k=0;

   while(seq[i]!='\0'){

       if(seq[i]!=' ' && seq[i]!='\t' && seq[i]!='\n'){

           cleanedSeq[k++]=seq[i];

       }

       i+=1;

   }

   cleanedSeq[k]='\0';

   for(int i=0;cleanedSeq[i]!='\0';i++){

       printLine(cleanedSeq[i],9,9);

       if(cleanedSeq[i]=='0') //if we encounter any zero we stop printing

           break;

   }

   return 0;

}
