Question description

Develop the function char** indexedKeysAndOPerators(const char * 

fName)  with the following specifications :

fName parameter represents the path name of a file + source code C + +. 

The return value represents an array of null terminated strings.

 For each  katholiko block of source code fName there is an element in the table return . 

The element is formed from the keywords and the operators of the respective blocks as follows : 

Each keyword (keyword) and / or operator (operator) encountered in block numbered and inserted numbered into string.  

Different keywords and / or operators have a different numbering . Also , the numbers are different for each block . 

The string produced for each ledger(katholiko) block of insertion code will name it representation of keys .

ledger,katholiko = called a code block that is not contained within another block


#include <iostream> 

#include <fstream> 

using namespace std ; 

void displayFile (const char * fName ) { 

//yellow area start

ifstream in; 

in.open (fName ); 

if (!in.is_open ()) { 

cout << fName << " not opened" << endl ; 


char buffer [1024 ]; 

while (!in.eof ()) { 

in.getline (buffer , sizeof (buffer )); 

cout << buffer << '\n' ; 

in.close (); 

//yellow area finish

int main (){ 

//green area start

displayFile ("main.cpp" ); 

return 0; 

//green area finish


The code above has 2 ledger blocks: the body of  displayFile (yellow area) and the body of main (green area). 

Therefore, the key representation for the yellow and green blocks are respectively as follows:

The yellow area have keywords as follows: 1 char, 2 cout, 1 endl, 1 

if, 1 while and operands: 1 [, 3 (), 5., 2!, 1 return and 5 (. 

� Similarly, in the green region have keywords as follows: 1 return and 

operators: 1. 1 (. 

Accordingly, indexedKeysAndOPerators will return an array of size 2 to 

contains the following strings

char1, cout1, cout2, endl1, if1, return1, while 1, [1, ()1, ()2, ()3, !1, !2, (1, (2, (3, (4, (5, .1,

.2, .3, .4, .5

return1, (1, .1

Add a main that takes as a parameter the name of a source code C + + and

will print on the screen the result of indexedKeysAndOPerators.

A list of keywords and operators given in file keywords.txt. The order of

keywords and operators can be changed in keywords.txt if deemed that

facilitate the implementation of indexedKeysAndOPerators.
