I get answer from your expert but when run the code the terminal write terminate called after throwing an instance of 'std::invalid_argument' what(): stoi Aborted (core dumped). : What should i change : Expert Answer Step 1 NOTE: Algorithm specified in the question is implemented in "checkAlgorithm.h". Test program to implement "checkAlgorithm.h" is specified in "fileCheck.cpp". Code for checkAlgorithm.h: #ifndef H_checkAlgorithm #define H_checkAlgorithm #include #include using namespace std; bool check(ifstream &file) { string s; int a, b; getline(file, s); a = stoi(s); while (!file.eof()) { getline(file, s); b = stoi(s); if (a > b) { return false; } a = b; } return true; } #endif Step 2 Code for fileCheck.cpp: #include "checkAlgorithm.h" int main() { int value; string str; ifstream inFile; bool result; cout << "\nEnter File Name to check: "; cin >> str; inFile.open(str); result = check(inFile); cout << "\n" << str; if (result) { cout << " is sorted" << endl; } else { cout << " is not sorted" << endl; } cout << endl; inFile.close(); }

Expert Answer

Step 1

NOTE:

Algorithm specified in the question is implemented in "checkAlgorithm.h".
Test program to implement "checkAlgorithm.h" is specified in "fileCheck.cpp".

Code for checkAlgorithm.h:

#ifndef H_checkAlgorithm

#define H_checkAlgorithm

#include <iostream>

#include <fstream>

using namespace std;

bool check(ifstream &file)

{

string s;

int a, b;

getline(file, s);

a = stoi(s);

while (!file.eof())

{

getline(file, s);

b = stoi(s);

if (a > b)

{

return false;

}

a = b;

}

return true;

}

#endif

Step 2

Code for fileCheck.cpp:

#include "checkAlgorithm.h"

int main()

{

int value;

string str;

ifstream inFile;

bool result;

cout << "\nEnter File Name to check: ";

cin >> str;

inFile.open(str);

result = check(inFile);

cout << "\n"

<< str;

if (result)

{

cout << " is sorted" << endl;

}

else

{

cout << " is not sorted" << endl;

}

cout << endl;

inFile.close();

}
