  1. FILE Teks dan Biner

  2. //program untuk menulis ke dalam file teks kemudian menampilkan isi file ke layar • #include <stdio.h> • #include <conio.h> • #include <stdlib.h> • Void main() { • const int mak 80; • file p; // deklarasi file File Teks

  3. // membuka file teks utk di isi • if( (p = fopen(“demo.txt” ,”w” ) ) == NULL) • { puts(“File tidak dapat di buka”); • exit(0); • } • // input dari keyboard dan di tulis ke file • char string[mak], jawab ; // deklarasi var

  4. do • { printf(“kalimat”); gets(string); • fprintf(p,”%s\n”,string); • printf(“lagi [ Y / T ]”); • scanf(“%c”,&jawab); • } while(toupper(jawab) ==‘Y’); • fclose(p); // tutup file jika sudah selesai

  5. //membaca file • if( (p = fopen(“demo.txt”,”r”) ) == NULL) • { puts(“File tidak dapat di buka”); • exit(1); • } • // tampilkan di monitor • while( (fscanf(p,”%s”,string)) != EOF) • printf(“%s\n”,string); • fclose(p); // tutup file • } // end program

  6. //program untuk menulis ke dalam file biner kemudian menampilkan isi file • #include <stdio.h> • #include <conio.h> • #include <stdlib.h> • Void main() • { • file p; // deklarasi file File Biner

  7. struct mhs • { char npm[8]; • int nilai; }; • mhs m; //deklarasi variabel • char jwb; //deklarasi variabel • // membuka file biner utk di isi • if( (p = fopen(“demo.dat” ,”wb” ) ) == NULL) • { puts(“File tidak dapat di buka”); • exit(0); • }

  8. // membaca dan simpan ke file biner • do • { • printf(“NPM “); gets(m.npm); • printf(“Nilai “); scanf(“%d”,&m.nilai); • fwrite(&m,sizeof(m),1,p); //save ke file • printf(“Lagi [Y/T]”);scanf(“%c”,&jwb); • } • while(toupper(jwb) ==‘Y’);

  9. // tampilkan ke layar • while( ( fread(&m,sizeof(m),1,p)) != NULL) • printf(“%s %d\n”,m.npm,m.nilai); • fclose(p); // tutup file • } // end program file biner

  10. Selesai
