Contoh 6: Piramida Penuh *
* * * * * * * * * * * * * * * * * * * * * * * * *
Program C
#include int main() ( int i, space, rows, k = 0; printf("Enter the number of rows: "); scanf("%d", &rows); for (i = 1; i <= rows; ++i, k = 0) ( for (space = 1; space <= rows - i; ++space) ( printf(" "); ) while (k != 2 * i - 1) ( printf("* "); ++k; ) printf(""); ) return 0; )
