自定义函数comparison声明和定义 写得不一样
float comparison(double[],int);
float comparison(float array[],int n)

自定义函数comparison（）中 理想返回值是float类型， 实际返回max ，而max是int类型，

#include<stdio.h>
#define NUMBER 6
float comparison(float[], int);


int main(void)
{
    float array[] = { 0.1,0.2,0.3,0.4,0.5,0.6 };
    comparison(array, NUMBER);
    printf("max=%f\n", comparison(array, NUMBER));

    
    return 0;
}
float comparison(float array[], int n)
{
    int i;
    float max;
    for (i = 1, max = array[0]; i<n; i++)
        if (max<array[i])
            max = array[i];

    return max;
}

#include<stdio.h>
#define NUMBER 6

float comparison(float array[],int n);

int main()
{
    float array[]={0.1,0.2,0.3,0.4,0.5,0.6};
    comparison(array,NUMBER);
    printf("max=%f\n",comparison(array,NUMBER));
   
    return 0;
}

float comparison(float array[],int n)
{
    int i;
    float max;
    for(i=1,max=array[0];i<n;i++)   
        if(max<array[i])                    
            max=array[i];
     
    return max;                     
}
函数声明时错了，max要为float类型

谢谢！

谢谢！
