Text analysis and editing

[Gregor007]

There's the text given (Duomenys.txt). The program removes vowels of the longest words in each line.

How do you redo the program to find numbers in the line (starting with -+0123456789) and insert the word NUMBER before these numbers (in the results file).

const char Cduom[] = "Duomenys.txt";      // data file
const char Crez[] = "Rezultatai.txt";     // results file
const char Canalize[] = "Analize.txt";    // analysis file
#include <string>
#include <fstream>
#include <iomanip>
using namespace std;

void ApdorotiTeksta(const char dfv[], const char rfv[], const char afv[]);   // work text
void AnalizuotiEilute(string eil, string & IlgZodis, int & IlgZPradzia, 
                     unsigned int & IlgZIlgis);                              // analyse text
void RedaguotiEilute(string &eil, int IlgZPradzia, int IlgZIlgis);           // edit line

int main()
{
  ApdorotiTeksta(Cduom, Crez, Canalize);                                     // work text

How do you redo the program to find numbers in the line (starting with -+0123456789) and insert the word NUMBER before these numbers (in the results file).

Find each word
Test the first character
If -/+/digit then output the word NUMBER
Output the word
Repeat.
