ditioFor loops are a little more complex then the While loop. A for loop as 3 optional parameters. They are the initializer list, the conditional check, and the post incrementer list.
The initializer list is the section that you declare variables and/or initialize them to a specific value.
The conditional check is the conditional check for the loop to continue or finish.
The post incrementer list is a section that is used to apply post loop code. Once each iteration of the loop is complete, these lines of code are called to update variables or conditions. Then the loop runs againns. Then the loop runs again

How do you make a function repeat itself in C plus plus?
There are three ways to do repetitions in C as far as I know. The first is to use recursion (a function which calls itself) the second being a for loop and the third being a while loop, though both of these are basically the same thing. Here's a demonstration of using these three methods to compute the x raised to the power of y: (note this isn't the most efficient way of calculating the power of a number but it's good enough for an example) //Recursion: int pow(int base, int pwr){ if(pwr == 0){ return 1; }else{ return base * pow(base, pwr - 1); } } //For loop int pow(int base, int pwr){ int i; int result = 1; //The for loop initialises i to the value of pwr, then //runs the loop, subtracting 1 from i each time until //i fails the test (i > 0) at which point the loop finishes for(i = pwr; i > 0; i--){ result *= base } return result; } //While loop int pow(int base, int pwr){ int result = 1; while(pwr > 0){ result *= base; pwr--; } return result; }
Why you need a for loop when you have already while loop or do while loop?
We need a for loop because the while and do-while loops do not make use of a control variable. Although you can implement a counter inside a while or do-while loop, the use of a control variable is not as self-evident as it is in a for loop. Aside from the use of a control variable, a for loop is largely the same as a while loop. However, it is quite different to a do-while loop, which always executes at least one iteration of the loop before evaluating the conditional expression. In a for and while loop, the conditional expression is always evaluated before entering the loop, which may result in the loop not executing at all.
What is the different between loop and do while loop?
no difference in logic in both of them you put the key to enter :while( ....),for(;....;) but infor loop you have option to initialize value and make operation on it for(int i=0;...;i++){} same int i=0; while(..){ i++;}
How does loop work?
In programming, a loop works by conditionally jumping to the start of the loop and repeating the instructions. If the condition evaluates false, execution continues to the next instruction, thus breaking out of the loop. We can also break out of a loop from within the body of the loop itself using another conditional jump which jumps out of the loop. If we jump backwards out of a loop we effectively create an intertwined loop, known as spaghetti code which is difficult to read and maintain. Structured loops help make it easier to digest the logic. In C, a jump is achieved using a goto and a label. However, structured loops using for, while and do-while statements make loops much easier to read and maintain.
What is do while loop in VB 6?
Structure: do (while(expression) or until(expression)) . . . loop (while(expression) or until(expression)) This is called a loop in VB and it is used to do something more than one times. It may be used without any of the parameters "while" or "until" but in such case you have to make your code exit of the loop or most likely your program is going to stop responding. The while parameter is used when we want the code in the loop to be executed WHILE the expression is True. Example: variable = variable + 1 The until parameter is used when we want the code in the loop to be executed until the expression gets True. Example: variable = variable + 1
