C语言 多级指针应用

当指针变量pp所指的变量Ip也是一种指针时，pp是一种指向指针的指针，称指针变量pp是一种多级指针。

#include <stdio.h>

char *con10[]={
"hello10", "world10","end10"
};

char *con11[]={
"hello11", "world11","end11"
};

char *con12[]={
"hello12", "world12","end12"
};

char *con13[]={
"hello13", "world13","end13"
};
//////
char **con1[]={
con10, con11, con12, con13
};

char *con20[]={
"第20", "201","202"

char *con21[]={

char *con23[]={

for(i=0;i<2;i++)
{
printf("4级指针\n");
for(j=0;j<4;j++)
{
for(k=0;k<3;k++)
printf(" %s ",ptr[i][j][k]);
printf("\n");
}
printf("\n");
}
