The Switch Statement

The switch statement is similar to the else-if construct but has more flexibility and a clearer format. Let's create a four function calculator using switch statement:

void main()
{
 float num1=1.0,num2=1.0;
 char operator;
 while(!(num1==0.0 && num2==0.0))
 {
  printf("Type number, operator, number\n");
  scanf("%f %c %f",&num1,&operator,&num2);
  switch(operator)
   {
    case'+':
    printf(" = %f",num1 + num2);
    break;
    case'-':
    printf(" = %f",num1 - num2);
    break;
    case'*':
    printf(" = %f",num1 * num2);
    break;
    case'/':
    printf(" = %f"num1 / num2);
    break;
    default:
     printf("Unknown Operator!");
   } 
 printf("\n\n")
 }
getch();
}


In the above code, the statement 'case' is working as 'if', while 'default' is working as 'else' statement...
