To Print it in linear fashion:
#include <stdio.h>

main()
{
//1 1 2 1 1 2 3 2 1 1 2 3 4 3 2 1 1 2 3 2 1 1 2 1 1
int i =0,j =0,k=0 ;

for(i =1; i<=4; i++)
{
for (j=1;j<=i;j++ )
printf("%d ",j);

for(j=i-1;j>=1;j--)
printf("%d ",j);
}
i--;

for(k = i-1;k >= 1;k--)
{
for (j=1;j<=k;j++ )
printf("%d ",j);

for(j=k-1;j>=1;j--)
printf("%d ",j);

}
}
