Example

示例

/* Program to print Hollow and Solid Rhombus star pattern */
#include 
int main() {
   int r, c, rows; //Hollow Rhombus
   int r1,c1, rows1; //Solid Rhombus
   clrscr();
   printf("Enter the Number of rows for Hollow Rhombus Pattern: ");
   scanf("%d", &rows);
   printf("
");
   for(r=1; r<=rows; r++){
      for(c=1; c<=rows-r; c++){
         printf(" ");
      }
      for(c=1; c<=rows; c++){
         if(r==1 || r==rows || c==1 || c==rows)
         printf("*");
         else
         printf(" ");
      }
      printf("
");
   }
   printf("
");
   printf("Enter the Number of rows for Solid Rhombus Pattern: ");
   scanf("%d", &rows1);
   printf("
");
   for (r1=1; r1<=rows1; r1++){
      for (c1=1; c1<=rows1-r1;c1++){
         printf(" ");
      }
      for (c1=1; c1<=rows1; c1++){
         printf("*");
