Bhs C Dasar - Chapter V

Array adalah kumpulan tipe data yang sejenis, kita dapat mendeklarasikan Array kedalam berbagai Dimensi

tampung[5]; // 1 Dimensi
tampung[5][5]; // 2 Dimensi
tampung[5][5][3]; // 3 Dimensi
...
.......
dan seterusnya
cara pendeklarasian :
int tampung[5];
float tampung[5];
char tampung[20];
int tampung[5][5];

angka 5 menjelaskan bawah kita mempunyai 5 data didalam variabel tampung cara pengisian langsung ;

int tampung[5] ={1,2,3,4,5};
float tampung[5] = { 1.0.2.0.3.0.4.0.5.0};
char tampung[5] = {'a','b','c','d','e'};

contoh pemakaian sebagai berikut :
#include
#include
char my_string[20] = "C hebat!";
int main()
{
int index;
printf("%s\n", my_string);
for (index = 0 ; my_string[index] ; index = index + 1)
printf("%c", my_string[index]);
printf("\n");

for(index = strlen(my_string) ; index > 0 ; index = index - 1)
printf("%c", my_string[index - 1]);
printf("\n");

return 0;
}

contoh lain :
#include
#include

int main()
{
int index;
char stuff[20], *pt;

strcpy(stuff, "This is a neat test.");
pt = stuff;
for(index = 0 ; index < 20 ; index++)
{
printf("A character is ---> %c\n", *pt);
pt++;
}

return 0;
}

#include
#include
int main()
{
int index;
char string1[6], string2[6], string3[6], all_three[18];

strcpy(string1, "one"); //mencopy string "one" kedalam varibel
string1
strcpy(string2, "two"); //idem
strcpy(string3, "three"); // idem

strcpy(all_three, string1);
strcat(all_three, " "); // mengosongkan isi variabel all_tree;

strcat(all_three, string2); // gabungkan isinya
strcat(all_three, " ");
strcat(all_three, string3);

for(index = 0 ; index < 10 ; index = index + 1)
printf("hasil stringnya ---> %s\n", all_three);
return 0;
}


#include
int main()
{
int index, array1[10], array2[10], arrays[10];

for(index = 0 ; index < 10 ; index = index + 1)
{
array1[index] = 2 + 2 * index;
array2[index] = 10 * (index + 1);
}

for(index = 0 ; index < 10 ; index = index + 1)
arrays[index] = array1[index] + array2[index];

for(index = 0 ; index < 10 ; index = index + 1)
printf("%4d %4d + %4d = %4d\n", (index + 1), array1[index],
array2[index], arrays[index]);

return 0;
}

Contoh penggunaan Array 2 Dimensi
#include
int main()
{
int i, j;
int big[8][8], large[25][12];

for (i = 0 ; i < 8 ; i++)
for (j = 0 ; j < 8 ; j++)
big[i][j] = i * j; /* perkalian tables */

for (i = 0 ; i < 25 ; i++)
for (j = 0 ; j < 12 ; j++)
large[i][j] = i + j; /* penambahan tabel*/

big[2][6] = large[24][10] * 22;
big[2][2] = 5;
big[big[2][2]][big[2][2]] = 177; /* big[5][5] = 177; */

for (i = 0 ; i < 8 ; i++)
{
for (j = 0 ; j < 8 ; j++)
printf("%5d ", big[j]);
printf("\n");
}

return 0;
}
