C面试24. (指针)定义一个含有20个元素的double型数组a
2022-07-07 01:40:00 【我不是萧海哇~~~~】
- (指针)定义一个含有20个元素的double型数组a,定义一个指针变量ptrDouble指向该数组的首地址,然后通过该指针变量给该数组各元素赋值(等于下标值乘以3.2+1.5)。接下来再让该指针指向数组a的a[10],从该元素起求后面所有元素的和
要求:
输出要求:1)输出该数组的所有元素;2)输出上面求得的10个元素的和;
编程要求:除了定义数组a外,程序关于数组a的一切操作都要通过指针变量ptrDouble来实现。
void ff(int *arr,int len)
{
int *ptrDouble=arr
