將char轉換爲堆棧的字符串<string>

Question

我正在使用堆棧和隊列進行作業的整個迴文程序。我們的教授讓我們編寫堆棧並從頭開始排隊，只針對字符串。我正在從文件中讀取文本並確定是否是句子迴文。我顯然需要將每個字符推入堆棧和隊列，但是，如何將字符推入接受字符串作爲參數的堆棧？

//get data from txt file 
void getData(Stack &myStack, Queue &myQueue) 
{ 
ifstream infile; 

string temp; 
int i = 0; 

infile.open("palindrome.txt"); 

if (!infile) 
{ 
    cout << "The file failed to open." << endl; 
    exit(-1); 
} 

while (getline(infile, temp)) 
{ 

    //remove spaces form sentences 
    temp.erase(remove_if(temp.begin(), temp.end(), ::isspace),temp.end()); 

//need to push each character into stack and queue here 
//there are 5 sentences total in the file to check 


    i++; 


}

std::string有一個構造回吐（計數，焦炭），像這樣：

char ch = 'A'; 
std::string str(1, ch);
