C++ Value Return Function that produces a true/false

[zamaam0728]

I am at the end of my first semester of C++, and I'm not sure what I should do to make this program meet the requested specifications. The assignment is as follows:

Write a function called ignoreCaseCompa re() that has two character (char) parameters. The function should return true if the two characters received represent the same letter, even if the case does not agree. Otherwise, the function should return false. Then, write a simple main() function that uses your ignoreCaseCompa re().

Additional instructions:

Here is the function heading:
bool ignoreCaseCompa re(char c1, char c2)

{

//Write the code to compare c1 with c2 and return true/false

}


Here is what I have:

#include <iostream>
 
using std::cout;
using std::cin;
using std::endl;
 
//function prototype
bool ignoreCaseCompare (char first, char second);
 
int main ()
{
    char first = ' ';
    char second = ' ';
 
    cout << "Enter a letter: ";
    cin >> first;
    cout << "Enter another letter: ";
    cin >> second;
 
    first = toupper(first);
    second = toupper(second);
 
    cout << "Are the letters the same? " <<
 
    return 0;
}
//******function defintions*****
bool ignoreCaseCompare (char one, char two)
 
{if (one == two)
return true;
else
return false;
}
 
    //end main function

This programs is much easier without the value-return function. Can anyone offer any advice or direction?

Okay. I made a couple of changes based on the last questions. The program is showing no errors, but the results are now displaying a 0 for false and a 1 for true. The last thing I need to figure out is how to get the display to read true/false instead of 1/0

#include <iostream>
 
using std::cout;
using std::cin;
using std::endl;
 
//function prototype
bool ignoreCaseCompare(char, char);
 
int main ()
{
    char first = ' ';
    char second = ' ';
    bool ansTrueFalse = false;
 
    cout << "Enter a letter: ";
    cin >> first;
    cout << "Enter a second letter: ";
    cin >> second;
 
    ansTrueFalse = ignoreCaseCompare (first, second);
    cout << "The two letters are the same: " << ansTrueFalse << endl;
    return 0;
    // end of main function
}
//****function defintions*****
bool ignoreCaseCompare (char a, char b)
 
    {
        if (toupper (a)== toupper (b))
        return true;
        else
        return false;
 
    }
 
 
 
//end of isSameCharacter

I think I've got it!!!

#include <iostream> 
 
using std::cout; 
using std::cin; 
using std::endl; 
 
//function prototype 
bool ignoreCaseCompare(char, char); 
 
int main () 
{ 
    char first = ' '; 
    char second = ' '; 
    bool ansTrueFalse = false; 
 
    cout << "Enter a letter: "; 
    cin >> first; 
    cout << "Enter a second letter: "; 
    cin >> second; 
 
    ansTrueFalse = ignoreCaseCompare (first, second); 
    cout << "The two letters are the same: ";
    {
    if (ansTrueFalse = true)
        cout << "true" << endl;
    else
        cout << "false" << endl;
    }
    return 0; 
    // end of main function 
} 
//****function defintions***** 
bool ignoreCaseCompare (char a, char b) 
 
    { 
        if (toupper (a)== toupper (b)) 
        return true; 
        else 
        return false; 
 
    } 
 
 
 
//end of isSameCharacter

cout << "The two letters are the same: " << isSameCharacter?"true":"false" << endl;

Doesn't work because of the relative operator precedences of << and ?: (look them up). This is not unusual because << has quite a high precedence so if you are trying to evaluate an expression in acout statement always enclose it in brackets, this should work

cout << "The two letters are the same: " << (isSameCharacter?"true":"false") << endl;

However the is an iomanipulator to do this for you, include <iomanip> and you can just put

cout << "The two letters are the same: " << boolalpha << isSameCharacter << endl;

[newb16]

cout << "The two letters are the same: " << ansTrueFalse?"t rue":"false" << endl;
It didn't work because priority of ternary (?:) operator is lower than shift (<<). Use parentheses.
