Tutorial-12: To calculate the value of previous date and generate its Decision Table based Test Cases

Inputs for the Tutorial: The present Date is an input as two integers a & b.

Objective of this Tutorial: There are two objectives of the tutorial like:

Objective 1: To write a Program in C⁺⁺ for the determining the value of previous dates based upon various combinations of present date as input.

Objective 2:

Decision Table Based testing for situations in which a number of combinations of actions shall be taken for different conditions. Four parts of decision table being covered shall be: Condition Stub, Action Stub, Condition Entries and Action Entries.

Solution Part 1: Program in C⁺⁺

#include
#include
int main()
{
int day, month, year, flag=0;
printf(” enter the day value;”);
scanf(“%d”,&day) ;
printf(“enter the month value;”);
scanf(“%d”,&month);
printf(“enter the year value;”);
scanf(“%d”,&year) ;
if(year> = 1900 && year< = 2025)
{
if(month==l||month==3||month==5||month==7||month==8||month==10||month==12)
{
if(day> = 1&&day<=31)
{
flag = 1;
}
else
{
flag = 0;
}
}
elseif (month==2)
{
int rval=0;
if(year%4==0)
{
rval=l;
if((year%100)==0 && (year%400)! = 0
{rval = 0;
}
}
if(rva1==&&(day>=1 &&day <=29))
{ flag = 1;
}
elseif (day>=1 &&day <=28)
{ flag = 1;
else
}
flag = 0;
}
}
if (flag)
{
if(day==1)
{
if(month==1)
{
year–;
day = 31;
month = 12;
}
else if(month==3)
{
int rval = 0;
if(year%4==0)
{
rval = 1;
if ((year%100) == 0 && (year%400): = 0)
{ravl = 0;
}
}
if (ravl==1)
{
day = 29;
month–;
}
else
{
day = 28;
month–;
}
}
else if (month==2|| month==4||month==6||month==9||month==)
{day = 31;
month–;
}
else
{
day = 30;
month–;
}
}
else
{
day–;
}
printf (“the next data is:%d-%d-%d”, day, month, year) ;
}
else
{
printf (“the entered data is invalid: %d-%d-%d, day, month, year)
{
getche();
return 1;
}
