All To Upper. Read a string from cin into word and modify it so that it has all uppercase letters.

Question

Read a string from cin into word and modify it so that it has all uppercase letters.

Samples:

Input: hello Output: HELLO

Input: h3Llo Output: H3LLO

Hints:

1. You can only change the code in the middle of this program - where it says YOUR_CODE.
2. There is no magic "capitalize them all" - you need to loop through each character and convert each to uppercase.
3. There is already code (that you can't change) to print out the word. Your job is to change the word, not print anything out yourself. (Though printing out extra info while debugging may be helpful)

Code:

#include <iostream>

#include <cctype>

using namespace std;

int main()

{

string word;

//Do not modify anything on or above the line below this

//YOUR_CODE_BELOW

//YOUR_CODE

//YOUR_CODE_ABOVE

//Do not modify anything on or below the line above this

cout << word;

}

Answer 1

#include <iostream>

#include <cctype>

using namespace std;

int main()

{

string word;

//Do not modify anything on or above the line below this

//YOUR_CODE_BELOW

string WORD=" ";

cout << "Input :>";

cin >> word;

int strLen = word.length();

for (int iLoop=0; iLoop<strLen; iLoop++)

{

char ch = toupper(word[iLoop]);

WORD = WORD+ch;

}

cout << WORD << endl;

//YOUR_CODE_ABOVE

//Do not modify anything on or below the line above this

cout << word;

}
