程序设计思路怎么写
#include <stdio.h> void fun(int a[], int n)
{
int i,t;
for (i=0; i<n/2; i++)
{
t=a[i];
a[i] = a[n-1-i];
a[n-1-i] = t;
}
}
void main()
{
int b[9]={1,2,3,4,5,6,7,8,9}, i;
printf("\nThe original data :\n");
for (i=0; i<9; i++)
printf("%4d ", b[i]);
printf("\n");
fun(b, 9);
printf("\nThe data after invert :\n");
for (i=0; i<9; i++)
printf("%4d ", b[i]);
printf("\n");
}
