# include <stdio.h> int main () { char operator ; double first, second; printf ( "Enter an operator (+, -, *,): " ); scanf ( "%c" , & operator ); printf ( "Enter two operands: " ); scanf ( "%lf %lf" , &first, &second); switch ( operator ) { case '+' : printf ( "%.1lf + %.1lf = %.1lf" , first, second, first + second); break ; case '-' : printf ( "%.1lf - %.1lf = %.1lf" , first, second, first - second); break ; case '*' : printf ( "%.1lf * %.1lf = %.1lf" , first, second, first * second); break ; case '/' : printf ( "%.1lf / %.1lf = %.1lf" , first, second, first / second); break ; // operator doesn't match any case constant default : printf ( "Error! operator is not correct" ); } return 0 ; } Output
