我试图让我的程序打印字母而不是数字。我曾经char c = static_cast<char>(N);尝试这样做，但它不起作用，而是打印不是 (az) 的字符图像 我怎样才能将数字打印为字母？
#include <cstdlib>
#include <iostream>
using namespace std;
// Function getUserInput obtains an integer input value from the user.
// This function performs no error checking of user input.
int getUserInput()
{
int N(0);
cout << endl << "Please enter a positive, odd integer value, between (1-51): ";
cin >> N;
if (N < 1 || N > 51 || N % 2 == 0)
{
cout << "Error value is invalid!" << "\n";
cout << endl << "Please enter a positive, odd integer value, between (1-51): ";
cin >> N;
system("cls");
}
cout << endl;
return N;
} // end getUserInput function
// Function printDiamond prints a diamond comprised of N rows of asterisks.
// This function assumes that N is a positive, odd integer.
void printHourglass(int N)
{
char c = static_cast<char>(N);
for (int row = (N / 2); row >= 1; row--)
{
for (int spaceCount = 1; spaceCount <= (N / 2 + 1 - row); spaceCount++)
cout << ' ';
for (int column = 1; column <= (2 * row - 1); column++)
cout << c;
cout << endl;
} // end for loop
// print top ~half of the diamond ...
for (int row = 1; row <= (N / 2 + 1); row++)
{
for (int spaceCount = 1; spaceCount <= (N / 2 + 1 - row); spaceCount++)
cout << ' ';
for (int column = 1; column <= (2 * row - 1); column++)
cout << c;
cout << endl;
} // end for loop
// print bottom ~half of the diamond ...
return;
} // end printDiamond function
int main()
{
int N = 1;
while (N == 1)
{
printHourglass(getUserInput());
cout << endl;
cout << "Would you like to print another hourglass? ( 1 = Yes, 0 = No ):";
cin >> N;
}
} // end main function
