Program

main()
{
int decimal, n, c, no=0 , deret, genap,ganjil,prima;
clrscr();
for (decimal=97; decimal<=122; ++decimal) {
printf (“%c”, decimal); } printf (“\n”);
for (decimal=65; decimal<=90; ++decimal) {
printf (“%c”, decimal); } printf (“\n”);
printf (“\nPiramid Angka\n”);
printf (“—————-”);
for (n=1;n<=5;n++) {
printf (“\n”);
for (c=1; c<=n; c++) {
++no;
printf (“%-3d”, no); }
}
printf (“\n\n”);
printf (“Bilangan genap 1-100:\n”);
for (deret=1; deret<=100; ++deret) {
genap=deret%2;
if (genap==0) printf (“%4d”, deret);  }
printf (“\n”);
printf (“Bilangan ganjil 1-100:\n”);
for (deret=1; deret<=100; ++deret) {
ganjil=deret%2;

printf (“\n\n”);
printf (“Bilangan prima 1-100:\n”);
for (deret=2; deret<=100; ++deret) {
for (prima=2;prima<=deret-1;++prima)
if (deret%prima==0) break;
if (deret==prima) printf (“%4d”, deret);
}
getch();
}


Setelah itu kita tekan F9, atau run program,

Dan akan keluar hasil seperti ini :
