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: }
