هذا التعديل .. والمعذرة زحمة اختبارات وتكاليف :(

if statment & switch لها نفس الاستخدام بس أحس السويتش مرنه أكثر عشان كذا حبيتها

السؤال الأول:

#include <iostream.h>
#include <conio.h>
void main()
{
	float x,y;
   char ch;
   cout<<" Enter the first number : ";
   cin>>x;
   cout<<"\n Enter the operator : ";
   cin>>ch;
   cout<<"\n Enter the scend number : ";
   cin>>y;
   if (ch=='*')
      cout<<" \n Answer = "<<(x*y);
   else if (ch=='/')
      cout<<" \n Answer = "<<(x/y);
   else if (ch=='+')
		cout<<" \n Answer = "<<(x+y);
   else if (ch=='-')
       cout<<" \n Answer = "<<(x-y);
   else cout<<"Error Enytry";

    getch();
    }

وهذا السؤال الثاني :

# include <iostream.h>
# include <conio.h>
void main(){
 float f, c;
 c=((f-32)*(5/9));
 f= (c *(9/5)+ 32);
 int x;
 cout<<"choose 1 to to convert Fahrenheit to Celsius";
 cout<<"\nOR 2 to convert Celsius to Fahrenheit"<<endl;
 cin>>x;
 if (x==1)
  { cout<<"\nEnter temperature in Fahrenheit :";
   cin>>f;
   cout<<"\nThe temperature in Celsius is: "<<c; }
 else if (x==2)
    {cout<<"\nEnter temperature in Celsius :";
    cin>>c;
    cout<<"\nThe temperature in Fahrenheit is:"<<f;}
 else cout<<"Error Entry";

 getch();
 }

بالــتوفيــق..
