Explanation:
# include <iostream> using namespace std; int main() { char op; float num1, num2; cout << "Enter operator: +, -, *, /: "; cin >> op; cout << "Enter two operands: "; cin >> num1 >> num2; switch(op) { case '+': cout << num1 << " + " << num2 << " = " << num1 + num2; break; case '-': cout << num1 << " - " << num2 << " = " << num1 - num2; break; case '*': cout << num1 << " * " << num2 << " = " << num1 * num2; break; case '/': cout << num1 << " / " << num2 << " = " << num1 / num2; break; default: // If the operator is other than +, -, * or /, error message is shown cout << "Error! operator is not correct"; break; } return 0; }
Output
Enter operator either + or - or * or divide : - Enter two operands: 3.4 8.4 3.4 - 8.4 = -5.0

Answer:
#include <stdio.h>
int main(){
char wish;
float num1,num2,result;
int flag =1;
printf(" Enter - , + , * ,/ for knowing result \n");
scanf("%c" , &wish);
printf ("Enter number 1\n");
scanf("%f", &num1 );
printf ("Enter number 2\n");
scanf("%f" , &num2 );
switch (wish)
{
case '+':
result =num1+num2;
break ;
case'-':
result =num1-num2;
break ;
case '/':
{
if (num2 ==0)
{
flag = 0;
}
else
{
result =num1/num2;
}
break ;
}
case'*':
result = num1 *num2;
break ;
default : printf ("error");
break ;
}
if (flag ==1)
{
printf ("%f %c %f =%f" , num1, wish,num2 ,result );
}
else
{
printf ("%f %c %f = undefined" ,num1 ,wish ,num2 );
}
}
