6.数组类型和数组指针类型

一.数组类型

typedef int MyArrayType[5];

void main() {

typedef int MyArrayType[5];
MyArrayType myArray;

int i = 0;
for (i = 0; i < 5; i++)
{
myArray[i] = i + 1;
}

for (i = 0; i < 5; i++)
{
printf("%d\n",myArray[i]);
}

int a[5];
MyArrayType *pArray = NULL; // 定义一个数组类型的指针
pArray = &a;

system("pause");

}

二.数组指针类型

typedef int(*MyPArrayType)[5];

void main() {

typedef int(*MyPArrayType)[5];
MyPArrayType myPoint; // 相当于定义一个指向int[5]类型的指针
int b[5];
myPoint = &b;

int i = 0;
for (i = 0; i < 5; i++)
{
(*myPoint)[i] = i + 1;
}

for (i = 0; i < 5; i++)
{
printf("b[%d] = %d\n",i,(*myPoint)[i]);
}
system("pause");

}

三.直接定义指针变量

int(*mypArrayPoint)[5];

void main() {

int c[5];
int(*mypArrayPoint)[5];
int i = 0;

mypArrayPoint = &c;

for (i = 0; i < 5; i++)
{
(*mypArrayPoint)[i] = i + 1;
}

for (i = 0; i < 5; i++)
{
printf("c[%d] = %d\n", i, (*mypArrayPoint)[i]);
}

system("pause");

}
