This article mainly introduces "how to prevent array subscript from crossing bounds in c language". In daily operation, I believe that many people have doubts about how to prevent array subscript from crossing bounds in c language. I have consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubt of "how to prevent array subscript from crossing bounds in c language" Next, please follow the editor to study!

1. If the array length and subscript access values are incorrect, it will cause the array subscript to exceed the bounds. The array subscript starts at 0 and the maximum access value is-1.

2. When using looping through array elements, be careful to guard against off-by-one errors.

The validity of the array subscript passed in as a function parameter should be judged.

Example

/ / in case of integer array int len = sizeof (array) / sizeof (int); / / in case of character array int len = sizeof (array) / sizeof (char); / / in case of floating point array int len = sizeof (array) / sizeof (double); / / in case of floating point array int len = sizeof (array) / sizeof (float); for (int I = 0 teri < len) At this point, the study on "how to prevent array subscript from crossing the bounds in c language" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
