Question

Use c++ programming environment to implement and test a function with the following prototype:

//the parameter month and day should represent a valid date

//return true if the date is between 3/8 and 10/31; false otherwise

bool is_daylight(int month, int day);

Following TDD (test-driven development), it is important to know the expected return values for different function calls.

Function call Expected return Function call Expected return is_daylight(2, 20) false is_daylight(3, 7) false is_daylight(4, 1) true is_daylight(10, 31) true is_daylight(11, 1) false is_daylight(12, 15) false

Answer 1

#include<iostream>

using namespace std;

bool is_daylight(int month, int day){

switch(month){ //parameters should be valid

case 3: if(day>=8 && day <=31)

return true;

case 4:

case 6:

case 9: if(day<=30 && day >=1)

return true;

case 5:

case 7:

case 8:

case 10: if(day<=31 && day>=1)

return true; //return true if all is well

}

return false; //return false otherwise

}

int main(){

cout<<is_daylight(4,1); // one test vase

return 0;

}
