The use of C two-dimensional character array and how to get the total number of rows and columns of the two-dimensional array!

#include <stdio.h> #include <stdlib.h>int main () {char str[][30] = {"Zhangsan", "Lisi", "Wangwu"};char (*p) [ +] = str; Define the row pointer printf ("%p%p%p Number of rows:%d columns:%d\n", str, &str[0], &str[0][0], sizeof (str)/sizeof (str[0]), sizeof (str[0])/ sizeof (str[0][0]));//number of rows = sizeof (array)/sizeof (array[0]);//number of columns = sizeof (array[0])/sizeof (array[0][0]); int i;for (i=0; I<sizeof (str)/sizeof (str[0]), i++) {printf ("%s \ n", * (P+i));} return 0;}
