Hello everyone~ Another week has passed~ I took Yueyue to the beach to play on the weekend. The little guy was very excited to see the sea for the first time. He said goodbye to the sea when he went to bed at night. Haha, how did you spend your weekend? There are many new good things to recommend to you in the past week. Come and have a look~ Wonderful post recommendation: #ST机械# @常常泽1 【Motor Kit P-NUCLEO-IHM】Chapter 7 Advanced Task Check-in [Motor Kit P-NUCLEO-IHM] Chapter 6 Task 1 Check-in @stp111 [ST Motor Evaluation] Task 1 [ST Motor Evaluation] Task Initialization - Environment Construction @yang_alex [Motor Kit P-NUCLEO-IHM Evaluation] -1.

xuezehui: I have gained a lot. 2. Modulo operation is not allowed for real variables. Although I have not encountered it, I will pay attention to it in the future. 10. The input and output types do not match the format specifier. I have encountered this problem before. It is disgusting. At that time, I used sorting to define the array as char type, and the results were not displayed correctly. This kind of problem is difficult to find unless you know the reason 16. Store the string directly in I have never used this method of character array. After learning it, I set up 3 variables, the first two are integers and the last one is float. When outputting, I set it to %d %f %f, as shown in the figure @alan000345 [url=https://en.eeworld.com/bbs/thread-649084-1-1.html]Should my country vigorously develop and invest in wireless charging technology for electric vehicles?

(2) How can you express the three numbers 2, three numbers 3, three numbers 4, etc. as the largest integer without using any operators?
