Source Code
#include <stdio.h>
int main()
{
int i,j,n;
printf("Enter a number: ");
scanf("%d", &n);
printf("\n");
for(i = n; i > 1; i--)
{
for(j = 1; j <= i; j++)
printf("*");
printf("\n");
}
for(i = 1; i <= n; i++)
{
for(j = 1; j <= i; j++)
printf("*");
printf("\n");
}
printf("\n");
for(i = 1; i < n; i++)
{
for(j = 1; j <= i; j++)
printf("%d",j);
printf("\n");
}
for(int i = n; i >= 0; i--)
{
for(int j = 1; j <= i; j++)
printf("%d",j);
printf("\n");
}
printf("\n");
return 0;
}
