Question # 2

What is sentinel controlled loop?

Ans 1: One way to do this is to instruct the user to enter a unique data value, called a sentinel value, after the last data item . The loop condition test s each data item and causes loop exit when the sentinel value is read. Choose the sentinel value is read.Choose the sentinel value carefully;
It must be a value that could not normally occur as data. The general form of a sentinel-controlled loop is;
1. Get the first line of data
2. While the sentinel value has not been encountered
3. Process the data line.
4. Get another line of data

Int c;
For (c=2; c < =5; c+ +)
{
Printf (" %C",c);
}
}

Question # 6

Int i =1;
While (I <=15)
{printf( "/n",1);
I = i+1;}

Ans 1: Conversion:
Void main ()

Int i =1;
Do
{
Printf("/n",1);
i =i+1;
} while ( i < =15);
}

{
Int i =1;
While(i< =10)
{
Printf("%\n",I);
I =i+1;
}}

Question # 8

Void main( )
{
Int x, y= 5;
For (x= 0; x < 3;x ++)
If (y > =5)
Print f ("%s\t",x);
}

Ans 1: Errors:
0 1 2

Question # 9

Int x= 10;
While (x> =1)
{ printf ("'%d", x%2);
x--;
}

Ans 1: Rewrite in do-while loop:
Void main ( )
{
Int x = 10;
Do
{
Printf("%d\n",x%2);
X=x-1;
}while (n>=1);
}

Question # 10

For (I =10; >0; i --)
{
printf ("i = %d",i);
}

Ans 1: Conversion:
Void main( )
{
Int I = 10;
While (i>0)
{
Printf("i = %d",i);
i = I -1;
}
}
