STRUKTUR KONTROL PADA C++, MEMBUAT NILAI SISWA MENGGUNAKAN SWITCH

Untuk 1 Kondisi 2 Syarat :

---------------------------------------------------------------------------------
nilai = 80
kehadiran = 50
if ((kondisi) && (kondisi))
     {
         statment 1;
         statment 1;
      }
else if (kondisi 2)
         statment 2;
else
         statment 3;
----------------------------------------------------------------------------------


Untuk If mempunyai 2 kondisi

----------------------------------------------------------------------------------
if (kondisi 1)
           statment;
else if
          statment;
else
          statment;
----------------------------------------------------------------------------------



Membuat Nilai_siswa dengan mengguanakan Switch !!

----------------------------------------------------------------------------------------------------------------------------

#include <conio.h>
#include <iostream.h>
#include <stdio.h>
void main()
{
     char nama[30], kelas[2];
     int hadir, uts, uas;
     float jml;
     long int grade;
     cout<<"Nama : "; cin>>nama;
     cout<<"Kelas : "; cin>>kelas;
     cout<<"\n";
     cout<<"Nilai";
     cout<<"------------------------------------------------\n";
     cout<<"Kehadiran : "; cin>>hadir;
     cout<<"UTS          : "; cin>>uts;
     cout<<"UAS          : "; cin>>uas;
     cout<<"------------------------------------------------\n";
     jml = (hadir+uts+uas) / 3;
     cout<<"Jumlah      : "<<jml<<endl;
     cout<<"------------------------------------------------\n";
     grade = jml*10;
     switch (grade/10)
{
     case 80:
     case 81:
     case 82:
     case 83:
     case 84:
     case 85:
     case 86:
     case 87:
     case 88:
     case 89:
     case 90:
     case 91:
     case 92:
     case 93:
     case 94:
     case 95:
     case 96:
     case 97:
     case 98:
     case 99:
     case 100:
cout<<"Grade : A "<<endl;
break;
      case 75:
      case 76:
      case 77:
      case 78:
      case 79:
cout<<"Grade : B "<<endl;
break;
      case 65:
      case 66:
      case 67:
      case 68:
      case 69:
cout<<"Grade : C "<<endl;
break;
      case 50:
      case 51:
      case 52:
      case 53:
      case 54:
      case 55:
      case 56:
      case 57:
      case 58:
      case 59:
cout<<"Grade : D "<<endl;
break;
default;
cout<<"Grade : E "<<endl;
}
   getch();
}

Atau yang lebih sederhana

-----------------------------------------------------------------------------------------------------------------------------

#include <conio.h>
#include <iostream.h>
#include <stdio.h>
void main()
{
     char nama[30], kelas[2];
     int hadir, uts, uas;
     float jml;
     long int grade;
     cout<<"Nama : "; cin>>nama;
     cout<<"Kelas : "; cin>>kelas;
     cout<<"\n";
     cout<<"Nilai";
     cout<<"------------------------------------------------\n";
     cout<<"Kehadiran : "; cin>>hadir;
     cout<<"UTS          : "; cin>>uts;
     cout<<"UAS          : "; cin>>uas;
     cout<<"------------------------------------------------\n";
     jml = (hadir+uts+uas) / 3;
     cout<<"Jumlah      : "<<jml<<endl;
     cout<<"------------------------------------------------\n";
     grade = jml*10;
     switch (grade/10)
{
     case 80..100:
cout<<"Grade : A "<<endl;
break;
      case 75..79:
cout<<"Grade : B "<<endl;
break;
      case 65..69:
cout<<"Grade : C "<<endl;
break;
      case 50..59:
cout<<"Grade : D "<<endl;
break;
default;
cout<<"Grade : E "<<endl;
}
   getch();
}
