程序打印菱形
原文:https://www . geesforgeks . org/c-program-print-diamond-shape/
给定一个数字 n，编写一个程序来打印一个 2n 行的菱形。
例:
![diamond]()
C++
// C++ program to print diamond shape
// with 2n rows
#include
using namespace std;
// Prints diamond pattern with 2n rows
void printDiamond(int n)
{
int space = n - 1;
// run loop (parent loop)
// till number of rows
for (int i = 0; i < n; i++)
{
// loop for initially space,
// before star printing
for (int j = 0;j < space; j++)
cout << " ";
// Print i+1 stars
for (int j = 0; j <= i; j++)
cout << "* ";
cout << endl;
space--;
}
// Repeat again in reverse order
space = 0;
// run loop (parent loop)
// till number of rows
for (int i = n; i > 0; i--)
{
// loop for initially space,
// before star printing
for (int j = 0; j < space; j++)
cout << " ";
// Print i stars
for (int j = 0;j < i;j++)
cout << "* ";
cout << endl;
space++;
}
}
// Driver code
int main()
{
printDiamond(5);
return 0;
}
// This is code is contributed
// by rathbhupendra
C
// C program to print
// diamond shape with
// 2n rows
#include
// Prints diamond
// pattern with 2n rows
void printDiamond(int n)
{
int space = n - 1;
// run loop (parent loop)
// till number of rows
for (int i = 0; i < n; i++)
{
// loop for initially space,
// before star printing
for (int j = 0;j < space; j++)
printf(" ");
// Print i+1 stars
for (int j = 0;j <= i; j++)
printf("* ");
printf("\n");
space--;
}
// Repeat again in
// reverse order
space = 0;
// run loop (parent loop)
// till number of rows
for (int i = n; i > 0; i--)
{
// loop for initially space,
// before star printing
for (int j = 0; j < space; j++)
printf(" ");
// Print i stars
for (int j = 0;j < i;j++)
printf("* ");
printf("\n");
space++;
}
}
// Driver code
int main()

printDiamond(5);
return 0;
