int main ( )
{
    
    for (int i = 1; i < 8; i++) {
        printf("                             ");
        for (int j = 1 ; j <= fabs(4-i); j++) {
            printf("   ");
        }
        for (int j = 1; j <= 2 * (4 - fabs(4-i)) - 1; j++) {
            printf("*  ");
        }
        printf("\n");
    }
    
}

With a feeling of absolute value less
the following is not a

#include <stdio.h>

int main()
{  	 	     	 
    int i, j, k;

    for (i = 1; i <= 4; i++)
    {  	 	     	 
        for (j = 1; j <= (4 - i) + 5; j++)
        {  	 	     	 
            printf("   ");
        }
        for (k = 1; k <= (2 * i - 1) + 5; k++)
        {  	 	     	 
            if (k <= 5)
            {  	 	     	 
                printf("   ");
            }
            else
            {  	 	     	 
                printf(" * ");
            }
        }
        printf("\n");
    }
    for (i = 1; i <= 3; i++)
    {  	 	     	 
        for (j = 1; j <= i + 5; j++)
        {  	 	     	 
            printf("   ");
        }
        for (k = 1; k <= (7 - 2 * i) + 5; k++)
        {  	 	     	 
            if (k <= 5)
            {  	 	     	 
                printf("   ");
            }
            else
            {  	 	     	 
                printf(" * ");
            }
        }
        printf("\n");
    }

    return 0;
}  	

the Output:
*
* * *
* * * * *
* * * * * * *
* * * * *
* * *
*
Program ended with Exit code: 0
friends, note the space, if it is the operating system, error-prone, it is blank spaces or blank spaces or blank spaces *
the number of lines too hurt
