无法打印用户填充的部分数组的反面

Question

对于分配，我们用用户定义的字符填充数组，一旦用户输入句号“。”，该字符将停止填充。作业的一部分是打印出在数组中输入的字符，但是我似乎什么也没打印。第一次问，很抱歉这是一个愚蠢的问题。预先感谢。

#include <iostream>
using namespace std;

//Function declarations
bool fillArray(char charArray[], int arraySize, int& numberUsed);
void outputInReverse(const char charArray[], int& numberUsed);

int main() {

    const int arraySize = 100;
    char charArray[arraySize] = { };
    int numberUsed = 0;

    //Function calls
    cout << "\nFILLING ARRAY....\n";
    fillArray(charArray, arraySize, numberUsed);


    cout << "\nARRAY OUTPUT....\n";
    outputInReverse(charArray, numberUsed);

}

//Function definitions
bool fillArray(char charArray[], int arraySize, int& numberUsed) {

    char inputChar;
    int index = 0;
    const char sentinel = '.';
    bool sentinelEntered = false;
    bool arrayFull = false;
    int count = 0;


    //Take user input
    for (int i = 0; i < arraySize; i++) {
        if ((!sentinelEntered)) {
            cout << "Enter up to " << arraySize << " character values. Enter full stop to end. " << "Enter char " << (i + 1) << ": " << endl;
            cin >> inputChar;
            charArray[index] = inputChar;
            //How many entries made
            numberUsed = i;
            count++;
            if ((inputChar == sentinel)) {
                sentinelEntered = true;
                cout << "Number of entries: " << (count - 1) << endl;
                return count;
            }
        }
    }
    if (numberUsed == arraySize) {
        arrayFull = true;
        return arrayFull;
    }
    return sentinelEntered;
    return count;
}

// Reverse 
void outputInReverse(const char charArray[], int& numberUsed) {
    for (int i = numberUsed; i > 0; i--) {
        cout << "Output in reverse: " << charArray[i] << endl;
    }
}
