while loop

Question

Could anyone explain the last question about while loop

Answer 1

syntax:-

initialization;
while(condition)
{//body of the loop starts here....
....
statements...
....
Increment/Decrements Operator
}//body of the loop ends here...

for example:-
print values from 1 to 10

int i;
i=1; //initialization of the variable i
while(i<=10) //condition is i is less or equal to 10
{
printf("%d\t",i); //prints the value of i
i++; //increment in the value of i means i=i+1
}

Output:-
1 2 3 4 5 6 7 8 9 10
In the above program first of all the value of i is initialized by 1 then the condition is check in while loop the condition is if i<=10 at this time the value of i is equal to 1 so (1<=10) is true means condition is true so compiler enters in the loop and execute next statement which prints the value of i which is 1 and then go to i++ operator which means i=i+1 (i=1+1) now i=2 and again condition is checked in while loop it continuous until condition is not true.

/t is used for tab space in printf statement.
