stopping until you meet break;for (;;) Like while (1), the For loop is the order of execution for (expression 1; expression 2; expression 3), the expression 1 is executed, the condition 2 is true, the loop body statement is executed and the expression 3 is executed, and then the expression 2 is judged until the expression 2 executes the following statement for the false jump loop. and for (;;) Is the expression 2 has been the green light has been circulating, but also encountered a break stop.
all corrected after the source program and running results:(ii) Study summary 1. Statement while (1) and for (;;) What is the meaning? , how to ensure that this cycle can be performed properly? A: Both of these are the meanings of infinite loops. The while (1) statement can add a break at the end to ensure that the loop jumps out. and for (;;) You can add one in the loop to make the loop work. 2. In general, when designing a looping structure, it is possible to use the for, while, does while
IE is not as stupid as we think. It knows that the total number of cycles is still 10 million. Therefore, we need to separate these one hundred cycles. Although Javascript is single-threaded, you can use setTimeout or setInterval to simulate multithreading. Suppose we want to generate 10 million random numbers. The general practice is as follows:

My friend said that you are dumb, breast enhancement and many simple things.Chinese medicine that can breast enlargement? Yizhijia was found by me and my friends. We learned about it on the official website and talked with customer service about it. I asked a lot of questions, saying that although I was 20 years old, but it is still in development, but the breast enlargement effect is certainly better. We recommend
recommended yizijiafeng breast to me. I tried all the methods, I don't think so. So I really bought it and used it. I didn't expect that after I had used yizijia for 3 cycles, my chest increased. In the past, I was not satisfied with all the bras with a cup, but after I increased it, I can bring a bra with a B cup, but it's a little tight, and I feel a lot more flexible. I'm really satisfied, what kind of products does yizhijia have on the market?In

She said she was using breast enhancement products. I said something, but she said it was yizhijia. You can search for it on the Internet. I said how can you use this? Does it have any bad effect. She said that many people have been using it for many years and are still full. The most important thing is my husband's lik

You can see at a glance that this product can allow the chest to take the initiative to absorb, rather than other products, are the same, so that the chest increases hard. Yizhijiamei cream is evenly distributed in the chest after being coated with an appropriate image, which can effectively guide the accumulation of free fatty acids in the body and increase the chest fat thickness to improve breast enlargement.

Clock cycle: the clock cycle, also known as the oscillation cycle, is defined as the reciprocal of the clock pulse frequency (the clock cycle is the reciprocal of the single-chip microcomputer external crystal oscillator, such as a 12 m crystal oscillator, the clock cycle is 1/12us), which is the most basic and minimum time unit in the computer, that is, the CPU clock speed. The clock pulse is the basic working pulse of the computer and controls the working rhythm of the computer. The higher the

Therefore, periodic power-up refresh operations are required to maintain the data. The refresh frequency is often dependent on the process of memory die and the des
