Question

Determine which are infite loops and why:

a. int i = 0;
    while(i<6){
         i = i * i;
    }

b. int i = 0;
    while(i<6){
          i--;
    }

c. int i = 10,000;
    while(i>=6){
         i--;
    }

d. int i = 1; while(i<6){
      i = i * 2;
    }

e. int i = 75; while(i>5){
         i = i / 5;

Answer 1

a and b are the infinite loops

a loop prints zeros because i is the values which gives same output as answer so loop does not get the where to stop .

ex.i = i * i always gives i let i=0 or i=1 both number gives always answer as o and 1 as final output so it will goes to infinite.

b loop is i - -; ( Decremented ) infinite and if loop is incremented then it will goes to 1 to 6 because loop i<6(ie. 0 < 6) but in case of our loop it will moves goes infinite

c loop prints 10000 to 5 numbers

d loop prints 2 4 8

e loop prints 15 and 3
