方法1：形参给出第二维的长度
|
#include <stdio.h>
void func(int n, char str[][5])
{
int i;
for (i = 0; i < n; i++)
{
printf("\nstr[%d] = %s\n", i, str[i]);
}
}
int main()
{
char str[][5] = {"abc", "def", "ghi"};
func(3, str);
return 0;
}
|
方法2：形参声明为指向数组的指针
|
#include <stdio.h>
void func(int n, char (*str)[5])
{
int i;
for (i = 0; i < n; i++)
{
printf("\nstr[%d] = %s\n", i, str[i]);
}
}
int main()
{
char str[][5] = {"abc", "def", "ghi"};
func(3, str);
return 0;
}
|
方法3：形参声明为指针的指针，实参传递指针数组
|
#include <stdio.h>
void func(int n, char **str)
{
int i;
for (i = 0; i < n; i++)
{
printf("\nstr[%d] = %s\n", i, str[i]);
}
}
int main()
{
char *p[3];
char str[][5] = {"abc", "def", "ghi"};
p[0] = &str[0][0];
p[1] = str[1];
p[2] = str[2];
func(3, p);
return 0;
}
|
方法4：形参声明为指向指针的指针，并对参数进行强制转换
|
#include <stdio.h>
void func(int n, char **str, int m)
{
int i;
char (*p)[m] = (char (*)[m])str;
for (i = 0; i < n; i++)
{
printf("\nstr[%d] = %s\n", i, p[i]);
}
}
int main()
{
char str[3][5] = {"abc", "def", "ghi"};
func(3, (char**)str, 5);
return 0;
}
