I need help with an assignment that deals with converting characters stored in a character array to all uppercase or all lowercase in C++. The textbook is Programming Logic and Design, Comprehensive 9th Edition (ISBN 978-1-337-10207-0). The following is the code that I have so far, and I would like to know what I am doing wrong: // ChangeCase.cpp - This program converts characters to lowercase and uppercase. // Input: Interactive // Output: Uppercase and lowercase versions of the user-entered string #include #include using namespace std; int main() { const int LEN = 9; char sample1[LEN]; char sample2[LEN]; char result1; char result2; int i; cout << "Enter 9 lowercase characters: "; for(i = 0; i < LEN; i++) { cin >> sample1[i]; // Convert sample1[i] to uppercase and assign it to result1 sample1[i] = toupper(sample1[i]); sample1[i] = result1; cout << result1 << endl; } cin.ignore(256,'\n'); cout << "Enter 9 uppercase characters: "; for(i = 0; i < LEN; i++) { cin >> sample2[i]; // Convert sample2[i] to lowercase and assign it to result2 sample2[i] = tolower(sample2[i]); sample2[i] = result2; cout << result2 << endl; } cin.ignore(256,'\n'); return 0; } // End of main() function

I need help with an assignment that deals with converting characters stored in a character array to all uppercase or all lowercase in C++. The textbook is Programming Logic and Design, Comprehensive 9th Edition (ISBN 978-1-337-10207-0). The following is the code that I have so far, and I would like to know what I am doing wrong:

// ChangeCase.cpp - This program converts characters to lowercase and uppercase.

// Input: Interactive

// Output: Uppercase and lowercase versions of the user-entered string

#include <iostream>

#include <string>

using namespace std;

int main()

{

const int LEN = 9;

char sample1[LEN];

char sample2[LEN];

char result1;

char result2;

int i;

cout << "Enter 9 lowercase characters: ";

for(i = 0; i < LEN; i++)

{

cin >> sample1[i];

// Convert sample1[i] to uppercase and assign it to result1

sample1[i] = toupper(sample1[i]);

sample1[i] = result1;

cout << result1 << endl;

}

cin.ignore(256,'\n');

cout << "Enter 9 uppercase characters: ";

for(i = 0; i < LEN; i++)

{

cin >> sample2[i];

// Convert sample2[i] to lowercase and assign it to result2

sample2[i] = tolower(sample2[i]);

sample2[i] = result2;

cout << result2 << endl;

}

cin.ignore(256,'\n');

return 0;

} // End of main() function
