使用for循环编写C++程序打印K形状字母图案。
#include<iostream>
using namespace std;
int main()
{
int i, j, alphabet, rows;
cout << "Enter K Shape Alphabets Pattern Row = ";
cin >> rows;
cout << "K Shape Alphabets Pattern\n";
for(i = rows - 1; i >= 0; i--)
{
alphabet = 65;
for(j = 0; j <= i; j++)
{
cout << char(alphabet + j) << " ";
}
cout << "\n";
}
for(i = 1; i < rows; i++)
{
alphabet = 65;
for(j = 0; j <= i; j++)
{
cout << char(alphabet + j) << " ";
}
cout << "\n";
}
return 0;
}

此C++示例使用while循环打印字母K形状图案。
#include<iostream>
using namespace std;
int main()
{
int i, j, alphabet, rows;
cout << "Enter K Shape Alphabets Pattern Row = ";
cin >> rows;
cout << "K Shape Alphabets Pattern\n";
i = rows - 1;
while(i >= 0)
{
alphabet = 65;
j = 0;
while( j <= i)
{
cout << char(alphabet + j) << " ";
j++;
}
cout << "\n";
i--;
}
i = 1;
while( i < rows)
{
alphabet = 65;
j = 0;
while( j <= i)
{
cout << char(alphabet + j) << " ";
j++;
}
cout << "\n";
i++;
}
return 0;
}
Enter K Shape Alphabets Pattern Row = 10
