Question

i need help with a c++ program, it will be reading characters in from a file using file stream

while the program is reading chartacter by charecter , it will identify what is it reading

so say a file contains this

x = 10; (This is one line)

y = 20;    (This is one line)                                                                                                                                                                                                                            

print x +y; (This is one line)                                                                                                                                                                                                                   

the outcome would be this

x is a word

10 is a number

y is a word

20 is a number

print is a word

x is a word

y is word   

i would like to see the correct outcomes just to see if the program actually runs

Answer 1

#include <iostream>

#include <string>

#include <fstream>

#include <sstream>

using namespace std;

int main()

{

string fileName = "file.txt";

string line;

fstream file;

file.open(fileName.c_str());

if(!file.good())

{

cout << "Problem with file!" << endl;

return 1;

}

while(!file.eof())

{

getline(file, line);

if(line.empty())

continue;

istringstream iss(line);

for(string word; iss >> word;)

if (isdigit(word[0]) != 0)

{

cout << word <<" is a number"<<endl;

}

else if(isalpha(word[0]) != 0)

{

cout << word <<" is a word"<< endl;

}

  

  

}

return 0;

}
