Which of the following go out of the loopo if expn 2 becoming falsea.while(expn 1){...if(expn 2)continue;}b.while(!expn 1){if(expn 2)continue;...}c.do{..if(expn 1)continue;..}while(expn 2);d.while(!expn 2){if(expn 1)continue;..}

The answer is very klear,as As the loop says when d expression1 is true it continues and then goes into the while condition to see dat if the expression 2 is true then only the loop continues,else breaks off from the loop when the expression2 goes false.

IEEE-754 Floating is used to store Float. So while storing float s store with encoded format. When i is used to access this value it reads 4 bytes which are nothing but IEEE-754 Floating encode. if you type that number in IEEE-754 Floating calculator it will show it as 100.

Yes. /*Array of Strings*/char* _animals[] = { "Tiger","Lion", "Dog", "Cat" };/*Array of ints*/int numbers[] = {1,2,3,4,5};number of elements of such arrays can be obtained bycount = (sizeof(_animals)/sizeof(_animals[0]));

Int *a=new int[];arrays and pointers are similar things .if now you want to access any element just type a[element no] and access the element.
