Question # 1

Convert the following do-while loop in for loop.

Int c=2;
Do
Printf ("C".c);
While (c + +< =5);

Ans 1: Conversion:
Void main ( )
{
Int c;
For (c=2; c < =5; c+ +)
{
Printf (" %C",c);
}
}

Question # 2

What is the output of the following code?
{
Int n =1;
While (n< =5);
{
Printf ("Islam Zindabad");
N= n+1;
}
Getch( );
}

Ans 1: Output:
Islam Zindabad
Islam Zindabad
Islam Zindabad
Islam Zindabad
Islam Zindabad

Question # 3

Predict the output from the following code.
Int n;
Clrscr ();
For (n = 5; n > = 1; n --)
Printf ("%d\n',n);
getch();

Ans 1: Output:
5

Question # 4

Define nested loop.

Ans 1: Nested Loop: Nested loop mean a loop inside the body of another loop.Nesting can be done up to any level. But as the level of nesting increase, the complexity of the nested loop also increase . There is no instruction on the type of loops (while , do-while , or for ) that may be placed in the body of other loops.
Example: we can place one or more while or so-while loops in the body for the loop. Similarly, one or more for loops can be placed in the body of while or do -while loop.

Question # 5

Write syntax of while loop, both for single statement and for multiple statement.

Ans 1: Syntax for Single Statement and Multiple Statements:
While (condition)
{
statements(s);
}

Question # 6

Convert the following loop Code into for loop code.
i= 3;
Do
{
Printf ("%d/n",i);
I + =3;
}
While (i < =21);

Ans 1: Conversion
Void main
{
int i:
for (i =3; i<=21; i + =3)
printf ("%d\n",i);
}

Question # 7

What is the following code in for loop.
Int n=1;
While (n< =10);
{
Printf("%d\n",n);
N++;
}

Ans 1: Conversion:
Void main ( )
{
Int n;
For (n=1; n< =10; n++)
Printf(("%d\n",n);)
}

Question # 8

Define for Loop.

Ans 1: For Loop: The for statement is another way of implementing loops in C. Because of its flexibility, most programmers prefer the for statement to implements loops.
Syntax: The syntax of the for loops is as follows:
For (initialization expression: test condition;
increment/decrement expression)
{
Statement(s);
}

Question # 9

Write the syntax of do -while loop, both for single statement and for multiple statement .

Ans 1: Syntax for Single Statement and Multiple Statement :
Do
{
Statement(s);
} while (condition);

Question # 10

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
