算法学习---求数组中的最大数

给定一个数组，取出这个数组中的最大数：
C语言实现：

1: #include <stdio.h>

2: 

3: int getMaxNum(int a[],int length)

4: {

5:     int max = 0 ;

6:     if(length <= 0)

7:     {

8:         return max ;

9:     }

10:     for(int i = 0 ; i < length ; i++)

11:     {

12:         if (max < a[i])

13:         {

14:             max = a[i] ;

15:         }

16:     }

17:     return max;

18:

19: }

20: 

21: int main()

22: {

23:     int array[] = {1,2,3,2,5,9,4,11,32,22,10,2};

24:     int length = 12 ;

25:     printf("Max num is:%d",getMaxNum(array,length)) ;

26:     getchar() ;

27: }

Java实现：

1: public class main {

2: 

3:     public static void main(String[] args) {

4:         // TODO Auto-generated method stub

5:         int []array = new int[]{1,6,8,2,4,5,9,11,3} ;

6:         System.out.println("最大数：" + getMaxNum(array)) ;

7:     }

8:     public static int getMaxNum(int[] array){

9:         int max = 0 ;

10:         if(array.length == 0)

11:         {

12:             return max ;

13:         }

14:         for(int i = 0 ; i < array.length ;i++)

15:         {

16:             if(max <= array[i])

17:             {

18:            max = array[i] ;

19:             }

20:         }

21:         return max ;

22:     }

23: }
