First, read the following eight questions. If you can do it without reading any materials. Congratulations! It should be okay. Because the complex combinations are all changed from the above eight types. 1. Define an integer 2. Define a pointer to the integer number 3. Define a pointer to the pointer, which is a pointer to the integer number. 4. Define an array with 10 integer numbers 5. Define an array wit

his input unit is the byte length of the entire array (4*5=20), so the memory address of a+1 is 2751200. In addition, when using sizeof, because it is a keyword, not a function, the array is not automatically converted to pointers, resulting in the length of the array (4*5=20). PS: if it is (int) a+1 then the result i

The left and right values in C. And compare the differences between array names and pointers for array elements. Left value: the symbol that appears on the left of the value assignment is sometimes called the left value. Right value: the symbol that appears on the right of the value assignment is sometimes called the right value. The compiler assigns an address (

Simply put, it is two words, efficiency. As we all know, in C function calls, parameters are passed by value, which means that a copy is generated for the real parameter during function calls, and then the function operates on this copy, that is, the function call that everyone knows will not modify the value of the real parameter, because the value is passed here. Because function parameters need to be copied, if this function parameter is an array
