cannot convert 'float*' to 'float'

#include<math.h>
#include<stdio.h>
#include<stdlib.h>

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

int main() {
    int k=5;
    float a[k+1];
    array(a[k+1],k);
}

float array(float a[],int n )// n = size of array
{
    printf("enter elements in order of increasing:\n");
    for(int i=0;i<n;i++) {
        printf("array[%d]:",i);
        scanf("%f",&a[i]);  
    }
    return a;
}                                   

I want to build a program for using a function to give an array with increasing float numbers but it has a bug and the compiler shows these errors:

[Error] cannot convert 'float*' to 'float' in return9
[Error] cannot convert 'float' to 'float*' for argument '1' to 'float array(float*, int)'

a is of type float*, the return type is float. You either need to return one float, or convert the return type to a pointer.
