Requirements:

1. 5 students from the keyboard input data,

2. According to one of five students failed to pass the door and the number of failed in the all course,

3. The retrieval student id for NUM 3 course grades of students, NUM by keyboard input,

If you want to learn, this topic is to write their own, question wrong post code
Hand in your homework to deceive the teacher, baidu's source code

CodePudding user response:

The operation is simple and simple, also said that difficult difficult, estimates that the teacher didn't speak a keyboard input of the abnormal situation needs, all kinds of after confirm the change of demand, ha ha. When using a keyboard too disgusted with text input source

These two lines of code to remove & amp; Is the address is right, because an array name ah
