Hi,
Can we declare a variable in switch statement before any case starts.
like as shown below,
switch(a)
{
int b=20;
case 1: printf("b is %d\n",b); break;
}

C++ function declarations:

1) isEmptyList():boolean {query} - determines whether a list is empty

2) getLengthList():integer {query} - returns the number of items in a list

3) insertList(in ndx:integer,
in newItem:ListItemType,
out success:boolean )
- inserts an item (newItem) at a given position (ndx) in the list. The success flag should indicate whether the insertion was successful.

4) removeItemList(in index:integer,
out success:boolean)
- deletes the item at a given position (index)in the list.
The success flag should indicate whether the insertion was successful.

5) retrieveItemList(in index:integer,
out dataItem:ListItemType,
out success:boolean) {query}
- copies the item at a given position (index) in the list as dataItem. The success flag should indicate whether the insertion was successful

6) compareList(in firstItem:ListItemType,in nxtItem:ListItemType): integer
- compares the 2 list-items;
returns -1 if (firstItem is less than nxtItem)
returns 0 if (firstItem is equal to nxtItem)
returns 1 if (firstItem is more than nxtItem)


C++ function definitions using the operations declared above:
7) replaceItemList(in myList: List,
in oldItem: ListItemType,
in nuItem: ListItemType,
out succ: boolean)
- replaces oldItem in the list with a new item (nuItem). The succ flag should indicate whether the replacement was successful.

8) maxList(in byList: List,
out flag: boolean): ListItemType
- returns the highest value in a list. The flag should indicate whether the operation was successful.

9) isUniqueList(in urList: List): boolean
- determines if the list contains unique items with no duplicates.

10) retrieveItemPostList(in aList: List,
in dataItem: ListItemType,
out ndex: integer,
out succss: boolean) {query}
- returns the ordinal position (ndex) in the list of item dataItem. The succss flag should indicate whether the insertion was successful.

I'm taking my first C++ class and I cannot figure out this question. After the following code executes, item has the value...??
string item = “ABCX34”;
item.replace(3, 1, “D”);

would it be..
ABCD34
ABD234
DDDX34 or
ADDD34
and for me could you explain why this is?

thanks everyone!

how we can count the number of repeted word in a string

Posted by Aruna Saraf on Wednesday, 02.3.10 @ 21:54pm | #94562

int do_openFile(void)
{
char *p ; /* pointer to outFileName */
char *m ; /* pointer to report date */
char *mon; /* month number in report date */



/* get output file name */
m = pk->CNCRptdate;
m += 2;
strncpy(mon, m, 2);

p = outFileName ;

strcpy(p, pi->CNDExtransit);
p += 5;
strcpy(p, monTab[atoi(mon)]);
p += 3;
strcpy(p, ".");
p += 1;
strcpy(p, "TXT");

/* Open a new file for writing, if file exists, its contents are destroyed
*/
if ((outfile = fopen(outFileName, "w")) == NULL)
{
printf (" \r");
printf ("fopen failed\n");
printf ("Please hit 'PRINT SCREEN' and then hit ENTER to abort...\n");
getch();
return (0);
};
}

Issue: When the control hits the first strncpy() function, it throws "Unhandled exception at 0x00401acd in ICRSEX2B.exe: 0xC0000005: Access violation writing location 0x0040258f."

Pls let me know if any other information is required.

Write a program that takes two integers L and H (i.e. lowest and
highest integer), and calls a function CalculateSum that computes the
sum of all the numbers between L and H. Finally, the program will
print the average of all these integer numbers by dividing the sum by
the number of integers between L and H. The program should assert if
L is less than or equal to H.
