//not exactly what you asked but will help ya
int main (void)
{
      float value1, value2;
      char operator;

      printf("Type in your expression.\n");
      scanf("%f %c %f", &value1, &operator, &value2);
      switch (operator)
{
     case '+':
     printf ("%.2f\n", value1 + value2);

     break;
     case '-':

     printf ("%.2f\n", value1 - value2);
     break;
     case '*':
     printf ("%.2f\n", value1 * value2);
     break;
     case '/':
    if ( value2 == 0 )
    printf ("Division by zero.\n");
    else
    printf ("%.2f\n", value1 / value2);
    break;
    default:
    printf ("Unknown operator.\n");
