Case2 (Always FALSE condition): Variables ‘i’ is initialized before ‘do-while’ loop to ‘20’; iteration is increment of counter variable ‘i’; condition is FALSE always as ‘0’ is provided that causes NOT to execute loop statements, but it is noted here in output that loop stateme...
The example forwhile Loop in Ccan re-written as follows: #include<stdio.h> #include<conio.h> void main() { int i=0; clrscr(); do{ i=i+1; printf("%d This will be repeated 5 times\n", i); }while(i!=5); printf("End of the program"); getch(); } ...

While vs Do While Let's consider the previous while loop boolean trigger example. If I had initialized the value of keepGoing as false, the code in the while loop would have never executed and only the word "Stopped" would have been written to the console. However, if I were to initial...

Boolean and pointer expressions are often used as loop controlling expressions. The boolean valuefalseand the null pointer value of any pointer type compare equal to zero. Keywords do,while Example References C17 standard (ISO/IEC 9899:2018): ...
The do while loop is an exit controlled loop, where even if the test condition is false, the loop body will be executed at least once. An example of such a scenario would be when you want to exit your program depending on the user input. For and while loops are examples of an entry...
Note that the while loop doesn't take any iterations, but the do-while executes its body once. This is because the looping condition is verified at the top of the loop block in case of while, and since the condition is false, the program doesn't enter the loop....
