Question

Write a new statement in the try block which may throw the exception of length_error. Test the statement. Submission guide: Upload a program and a screenshot with your explanation about the output. -- // Handling out_of_range and length_error exceptions. #include #include using namespace std; int main() { string sentence; //Line 1 string str1, str2, str3; //Line 2 try //Line 3 { sentence = "Testing"; //Line 4 cout << "Line 5: sentence = " << sentence << endl; //Line 5 cout << "Line 6: sentence.length() = " << static_cast(sentence.length()) << endl; //Line 6 str1 = sentence.substr(8, 20); //Line 7 cout << "Line 8: str1 = " << str1 << endl; //Line 8 str2 = sentence.substr(28, 10); //Line 9 cout << "Line 10: str2 = " << str2 << endl; //Line 10 str3 = "Exception handling.

Explanation / Answer

#include <iostream>

#include <string>

using namespace std;

int main()

{

string sentence; //Line 1

string str1, str2, str3; //Line 2

const unsigned desired_length(26);

try //Line 3

{

sentence = "Testing string exceptions!"; //Line 4

cout << "Line 5: sentence = " << sentence

<< endl; //Line 5

cout << "Line 6: sentence.length() = "

<< static_cast<int>(sentence.length())

<< endl; //Line 6

str1 = sentence.substr(8, 20); //Line 7

cout << "Line 8: str1 = " << str1

<< endl; //Line 8

str2 = sentence.substr(28, 10); //Line 9

cout << "Line 10: str2 = " << str2

<< endl; //Line 10

str3 = "Exception handling. " + sentence; //Line 11

cout << "Line 12: str3 = " << str3

<< endl; //Line 12

str1.resize(str1.max_size() + 1, ' ');

}

catch (out_of_range re) //Line 13

{

cout << "Line 14: In the out_of_range "

<< "catch block: " << re.what()

<< endl; //Line 14

}

catch (length_error& le) //Line 15

{

cout << "Line 16: In the length_error "

<< "catch block: " << le.what()

<< endl; //Line 16

}

return 0; //Line 17

}
