Question

HELP NEEDED in C++ (preferred) or any other language

Write a simple program where you create an array of single byte characters. Make the array 100 bytes long. In C this would be an array of char. Use pointers and casting to put INTEGER (4 byte) and CHARACTER (1 byte) data into the array and pull it out.

Make sure you can access both character and integer data at any location in the array.

Read data from a text file. Pick any random txt file, an article or even the Bible.

Use regular expressions, strtok or any command you want including something you write yourself to break a line of text read from a file into tokens. A token is just a sequence of characters without a separator. The only separator you need is space ' ' but if you want to use more like, comma ',', tab '\t' and semicolon ';' go for it.

C++ code with delimiters only space using stringstream class

#include <bits/stdc++.h>

using namespace std;

int main() {

  //-----------part 1------------------

  char arr[100]={0};

  int x=1234;

  char ch='A';

  cout<<"Character: "<<ch<<"    Integer: "<<x<<endl;    //print character and integer

  arr[0]='A';

  int i=1;

  string num=to_string(x);  //convert number to string

  for(int j=0;j<num.size();j++) //put string characters in array

    arr[i++]=num[j];

  cout<<arr<<endl;  //print array

  char ch2=arr[0];  //extract char

  int n=0;

  i=1;

  while(arr[i]>='0' && arr[i]<='9'){    //till character is a digit

    n=n*10;

    n=n+arr[i]-'0';

    i++;

  }

  cout<<"Character: "<<ch2<<"    Integer: "<<num<<endl;    //extracted character and integer

  

  //--------------part 2--------------------

  cout<<"------------------------------------\n";

  fstream file;

  file.open("sample.txt");  //open file

  string line;

  getline(file,line);   //read first line from file

  file.close();

  string word;

  stringstream ss(line);

  while(ss>>word)

    cout<<word<<endl;

  return 0;
