POINTER DAN STRING

POINTER DAN STRING

//Contoh9_5
#include <iostream.h>
#include <conio.h>
void misteri1(char *);
void main() {
char string[] = "amikom";
cout<< "String sebelum proses adalah " << string <<"\n" ;
misteri1(string);
cout<<"String setelah proses adalah "<<string;
getch();
}
void misteri1(char *s) {
while ( *s != '\0' ) {
if ( *s >= 'a' && *s <= 'z' )
*s -= 32;
++s;
}
}


 POINTER MENUNJUK SUATU ARRAY

//Contoh9_6
#include "iostream.h"
#include "conio.h"
void main()
{ static int tgl_lahir[] = { 13,9,1982 };
int *ptgl;
ptgl = tgl_lahir; /* ptgl berisi alamat array */
cout<<"Diakses dengan pointer\n";
cout<<"Tanggal = "<< *ptgl<<"\n";
cout<<"Bulan = "<< *(ptgl + 1) <<"\n";
cout<<"Tahun = "<<*(ptgl + 2) <<"\n";
cout<<"\nDiakses dengan array biasa\n";
cout<<"Tanggal = "<< tgl_lahir[0] <<"\n";
cout<<"Bulan = "<< tgl_lahir[1] <<"\n";
cout<<"Tahun = "<< tgl_lahir[2] <<"\n";
getch();
}

MEMBERI NILAI ARRAY DENGAN POINTER

//contoh9_7
#include "iostream.h"
#include "conio.h"
void main()
{ int x[5], *p, k;
clrscr();
p = x;
x[0] = 5;
x[1] = x[0];
x[2] = *p + 2;
x[3] = *(p+1) - 3;
x[4] = *(x + 2);
for(k=0; k<5; k++)
cout<<"x["<<k<<"] = "<< x[k]<<"\n";
getch();
}
