标题: c语言形参数组不定义长度

1. #include<stdio.h>
   
2. float ave(float c[],int n)//这里形参数组不定义长度
   
3. {
   
4. int i;
   
5. float sum=0,av;
   
6. for(i=0;i<n;i++)
   
7. {
   
8. sum=sum+c[i];
   
9. }
   
10. av=sum/n;
    
11. return(av);
    
12. }
    
13. void main()
    
14. {float a[5]={98.5,97,91.5,60,55};
    
15. float b[10]={67.5,89.5,99,69.5,77,89.5,76.5,54,60,99.5};
    
16. //现在我们有两组数
    
17. printf("average_1=%f\n",ave(a,5));
    
18. printf("average_2=%f\n",ave(b,10));
    
19. 
    
20. 
    
21. }
