In this code,the windows of the house are rectangular.Is there any modification that can be made to change them into diamond shapes.I tried a lot,but the windows came one below the other.

Code:
#include<stdio.h>
void main() 
{
    int i,j,k;
    for(i=1;i<=10;i++)
    {
        for(j=1;j<=10-i;j++)
        {
            printf(" ");
        }
        for(j=1;j<=i;j++)
        {
                      printf("=");
        }
        for(j=1;j<=50;j++)
        {
        if(((i>=3&&i<=8)&&(j>=3&&j<=8))||((i>=5&&i<=6)&&    (j>=9&&j<=18))||((i>=3&&i<=8)&&(j>=19&&j<=24))||((i>=3&&i<=4)&&(j>=27&&j<=48))||((i>=5&&i<=6)&&(j>=37&&j<=39))||((i>=7&&i<=8)&&(j>=27&&j<=48)))


                printf(" ");
        else
            printf("=");
        }
        for(j=1;j<=i;j++)
        {
            printf("=");
        }
    printf("\n");
    }
for(i=1;i<=25;i++)
{
    for(j=1;j<=10;j++)
    {
                     printf(" ");
    }
        for(j=1;j<51;j++)
        {
if(((i>=5&&i<=9)&&(j>=3&&j<=10))||((i>=5&&i<=9)&&(j>=41&&j<=48))||((i>=13&&i<25)&&(j>=20&&j<=31)))
                      printf(" ");
else
    printf("=");
    }
        printf("\n");
    }
}
