Question

What is difference between conditional construct and loops

Answer 1

Conditional Statement: It is a statement which checks for a condition. It is used for decision making.

types of conditional statements :

>if

>if-else

>nested if

For example: if(x>=0) Print “positive number”

here ‘if’ is a conditional statement..

loop: if you want a block of statements to execute multiple number of times, the You can go for loops. There are three types of loops:

>while

>do-while

>for

while: it is a loop in which you check the condition before entering the loop.

Ex:

x=0;

while(x!=10){

print x;

x++;}

here first it checks if x is not equal to 10. Only if this condition gets satisfied, then it will enter the loop.

do-while: we execute a block of statements once before checking the condition.

Ex:

x=0;

do{

print x;

x++;

}while(x!=10);

(observe the semi colon at the end of do while)

for: if you certainly know how many number of times you want to execute a block of statements, then you can you for loop.

ex: for(I=0;I<n;I++){

print i;

}

Answer 2

Conditional Construct:

1. It runs only once.

2. compare two or more variables.

Ex: If, elseif, nested it and so on.


Loops:

1. Execute a multiple number of times.

2. Designed to repeat, while a certain condition is true.

Ex: While, for, do while and so on.
