Explanation / Answer

1.

#include <iostream>
#include <string>

int main()
{
int i;
std::cin>>i;
  
try{
if(i == 1)
throw "out_of_range";
else
throw "system_error";
}catch(std::logic_error &e){
       std::cout<<"ok";
}catch(...){
std::cout<<"Unknown";
}
return 0;
}

USER ENTER 1 : Unknown

USER ENTER 2 : Unknown

2.

try{

// do whatever

}catct(Exception &e){

// handle exception

}

catct(logic_error &e){

// handle logic error exception

}

catct(domain_error &e){

// handle domain error exception

}

Ans: Always catch block eith exception will execute because exception is the super class of the logic_error and domain_error classes.So we should write catch block with exception at the end of the catch block.

3.

what #includes should be listed at the top of main.cpp?

Ans: #iinclude<iostream>

#include "core.cpp"

#include "tools.cpp"

what #includes should be listed at the top of core.cpp?

Ans: #iinclude<iostream>

#include<core.h>

#include "tools.cpp"

#include "utilities.cpp"

4. Function declaration : Header file

Class definition : Source file.

Method definition : Source file.

Function definition : Header file

5.

code:

#include<iostream>
#include<fstream>

using namespace std;

int main() {

ifstream myReadFile;
myReadFile.open("words.txt");
char output[100];
int count=0;
if (myReadFile.is_open()) {
while (!myReadFile.eof()) {
myReadFile >> output;
   count++;
}
}
myReadFile.close();
cout<<"Number of lins(words):"<<count;
return 0;
}
