I've got following code I want to execute the query first and then return result. How should I do it. I've also done it with simple for loop but does not work. I think you just need to call next() aft... what is the difference between \c and \\c?
do While LoopDo While loop is little different than while loop. Here the condition is checked at the end of the loop. So even if the expression is FALSE then also once the statements inside the loop will be executed. This is the basic difference between do while loop and while loop. ...

5. Difference between While Loop and Do While Loop The main difference between a while loop and a do-while loop in Java lies in their execution and condition checking: While Loop: In a while loop, the condition is checked before the execution of the loop’s body. If the condition evaluat...
Difference between while and do-while loop in C, C++, Javawhile 循环:while 循环是一种控制流语句,它允许根据给定的布尔条件重复执行代码。 while 循环...
int i = 0;do { cout << i << "\n"; i++;}while (i < 5); Try it Yourself » Do not forget to increase the variable used in the condition, otherwise the loop will never end!Exercise? What is a key difference between a do/while loop and a while loop? A do/while loop wi...
The while loop in C++ first checks the test condition to see if the loop body will be executed. Learn about while, nested, and infinite while loops with examples.
We use FOR to iterate over a known range of values and WHILE to evaluate an expression. for (initialization; termination; increment) { statement(s) } while (expression) { statement(s) } The difference between WHILE and DO WHILE is that on WHILE it checks the condition first, than execute...
Difference Between while and do…while Loop Thewhileloop differs from thedo-whileloop in one important way — with awhileloop, the condition to be evaluated is tested at the beginning of each loop iteration, so if the conditional expression evaluates to false, the loop will never be executed...
