1. Int (*p) [10]:Depending on the binding law of the operator, () has the highest precedence, so p is a pointer to a one-dimensional array with a dimension of 10. p a line pointing to an array Copy Code code as follows: int a[1][4]={1

int main(int argc,char * argv[]) Argv is a pointer. Argc is an integer   char **argv or: char *argv[] or: char argv[][] The main () brackets are fixed. The following is an example to understand the usage of these two parameters: Assume that the

If the result is positive, the int and 11 values in int (11) must match the int (11) and int values. that is to say, if no parentheses are followed, only int values are matched. PHPcode $ str = & lt; & lt; please match int (11) and intDOC;

Example: Int sloth = 3; Const int * P1 = & sloth; Int * P2 const = & sloth; In this statement, P1 cannot be used to modify the sloth value, but P1 can point to other addresses; You can use p2 to modify the sloth value, but P2 cannot point to other

* A [5] is a pointer array that can point to 5 values.(* A) [5] is a pointer, but this pointer can only point to a one-dimensional array containing five elementsA is an array, and each element is a pointer.B is a pointer pointing to an array1. int *
