Pattern Diamond

Write a program to output Diamond?

1:  #include<stdio.h>  
2:  #define PARA 12  
3:  int main() {  
4:       int i,d;  
5:       i = (PARA/2);  
6:       d = (PARA/2);  
7:       int row,col;  
8:       for(row = 0 ; row <= (PARA/2) ; row++) {  
9:               for(col = 0 ; col <= PARA ; col++) {  
10:                        if(col == i || col == d) {  
11:                                 printf("*");  
12:                        }  
13:                        else {  
14:                                 printf(" ");  
15:                        }  
16:               }  
17:               i++;  
18:               d--;  
19:               printf("\n");  
20:       }  
21:       i = 1;  
22:       d = (PARA-1);  
23:       for(row = 0 ; row < (PARA/2) ; row++) {  
24:                for(col = 0 ; col <= PARA ; col++) {  
25:                      if(col == i || col == d) {  
26:                              printf("*");  
27:                      }  
28:                      else {  
29:                              printf(" ");  
30:                      }  
31:                }  
32:                i++;  
33:                d--;  
34:                printf("\n");  
35:       }  
36:  }  

Output:-

Note:- You can increase or decrease the size of diamond. For this just change the value of MACRO "PARA"
i.e #define PARA 12
But the value of PARA should be EVEN....
