指针加法

char*

char arr1[] = { 'a', 'b', 'c', 'd' };
char *p = arr1;
printf("%p\n", p);
p++; //地址加1个字节
printf("%p, %c\n", p, *p);
p += 2; //地址加2个字节
printf("%p, %c\n", p, *p);

 

float*

float arr2[] = { 1.0f, 3.0f, 6.0f, 7.0f };
float* p2 = arr2;
printf("%p\n", p2);
p2++; //地址加4个字节
printf("%p, %.2f\n", p2, *p2);
p2 += 2; //地址加8个字节
printf("%p, %.2f\n", p2, *p2);

 

其他类型以此类推
