To illustrate:function declaration: void Fun (int (*p) [4]);void Fun (int (*p) [4]){int i=0,j=0;for (i=0;ifor (j=0;jcout }P is a pointer to a[0], then P+i is a pointer to A[i], * (p+i) is a pointer to a[i][0],Then * (p+i) +j is a pointer to a[i][j],

In the standard library of C, the input and output functions of the standard libraries of printf, scanf, sscanf, sprintf, sscanf, parameters are variable. When debugging a program, we may want to define a variable output function to record the log,
