将一个数组倒装入另一个数组中,用指针的c语言程序

Answer 1

#include <stdio.h>

void fun(int data1[],int data2[],int size)
{
int *p;
int i = 0;
p = data1;
for(i = 0; i <= size; i++)
{
data2[size-i-1] = *p;
p++;
}

}

int main(void)
{
int data1[5] = {1,2,3,4,5};
int data2[3] = {0};
int i = 0;

if(sizeof(data1) < sizeof(data2))
fun(data1,data2,sizeof(data1)/4);
else
printf("目标数组内存长度不够\n");
//输出数组
for(i = 0;i < sizeof(data2)/4;i++)
{
printf("%d ",data2[i]);
}
printf("\n");
return 0;
}
