Title
Body
What is the difference between while loop and do while loop. I used to think both are completely same.Then I came across following piece of code: do { printf("Word length... "); scanf("%d", &wdlen); } while(wdlen<2); This code works perfectly. It prints word length and tascans the input. But when I changed it to while(wdlen<2){ printf("Word length... "); scanf("%d", &wdlen); } It gives a blank screen. It do not work. So there is some functional difference between both loops. Can anybody explain it? Is there any other difference in these two?
