Question No: 17 ( M a r k s: 2 )
How a program can use a function?
Answer: Calling program need to write the name of function and provide the arguments without the data types of arguments.
When we call a function we don’t give data type of retuning variable or for arguments.
Question No: 18 ( M a r k s: 2 )
Which function is used to read/write more than a single character or single line while handling files?
We use the getline function to read more than single charcter
Question No: 19 ( M a r k s: 2 )
Suppose the pointer yptr is pointing to the first element of the array y and the size of array is 10. Can we increment the yptr up to 12 times? And what will happen?
It may carry the memory address which which is not readable.. we can increment it.
Question No: 20 ( M a r k s: 3 )
(i) An array
day is declared as: int day[] = {1, 2, 3, 4, 5, 6, 7};
How many elements does array 'day' has?
(ii) If the declaration is changed as: int day[7] = {1, 2, 3, 4, 5, 6, 7};
How many elements does array 'day' has?
In both the case array day will have the 7 elements. Of int type
Question No: 21 ( M a r k s: 3 )
What is the difference between tellg() and tellp() functions?
tellg()
tellg () : function gives us the current get position of the file
pointer. It returns a whole number of type long, which is the position
of the next character to be read from that file.
tellp() function is used to determine the next position to write a
character while writing into a file. It also returns a long number
Question No: 22 ( M a r k s: 5 )

{myarray[i] = tolower(myarray[i]);}
{myarray[i] = toupper(myarray[i]);}
}
}
