如何用递归算法判断一个数组是否递增

题  目 ：如何用递归算法判断一个数组是否递增

C实现：

#include <stdio.h>
bool isIncrease(int a[], int len)
{
int n = len - 1;
if(n==0)
return 1;
else
{
if(a
>=a[n-1])
isIncrease(a,len-1);
else
return 0;

}

}
int main()
{
int a[] = {2,3,4,7,9,12,7};
int len = sizeof(a)/sizeof(a[0]);

int res = isIncrease(a,len) ;
if (res==1)
printf("a is an Increase array");
else
printf("a isn't an Increase array!");

return 0;

}
