Ubuntu C編程預期的浮點數，但參數類型爲double *

-1

我想編寫一個計算面積和體積以及給定數字的平均值的程序。我成功完成了這些工作，但是當我嘗試計算標準偏差時我不知道如何解決，我甚至couldn`t明白究竟是什麼問題，所以作爲我的最後的手段，我請你們help.Thanks這裏是我的代碼Ubuntu C編程預期的浮點數，但參數類型爲double *

#include <stdio.h> 
#include <math.h> 
int squaresarea(int edge) 
{ 
    int area = edge * edge; 
    printf ("Area of the square : %d\n",area); 

    return 0; 
} 
int rectanglesarea(int edge1,int edge2) 
{ 
    int rectanglesarea = edge1 * edge2; 
    printf ("Area of the rectangle : %d\n",rectanglesarea); 
} 
float spheresvolume(int radius) 
{ 
    float spheresvolume = (4.0/3)*M_PI*radius*radius*radius; 
    printf("Volume of the sphere: %f\n",spheresvolume); 
} 
float cylindersvolume(float radius1,float height) 
{ 
    float cylindersvolume = M_PI*radius1*radius1*height; 
    printf("Volume of the cylinder %f\n",cylindersvolume); 
} 
double average(float edge,float edge1,float edge2,float radius,float radius1,float height) 
{ 
    double average = (edge + edge1 + edge2 + radius + radius1 + height)/6; 
    printf("Average of the values entered: %f\n",average); 
} 
double standarddeviation(int edge,float average) 
{ 

    double standarddeviation = (edge - average); 
} 
int main (int edge,int edge1,int edge2,int radius,int radius1,int height) 
{ 
    printf("Enter the length of your square`s edge: "); 
    scanf("%d",&edge); 
    squaresarea(edge); 
    printf("Enter the lengths of your rectangles edges:"); 
    scanf("%d %d",&edge1,&edge2); 
    rectanglesarea(edge1,edge2); 
    printf("Enter radius of your sphere: "); 
    scanf("%d",&radius); 
    spheresvolume(radius); 
    printf("Enter radius and height of your cylinder: "); 
    scanf("%d %d",&radius1,&height); 
    cylindersvolume(radius1,height); 
    average(edge,edge1,edge2,radius,radius1,height); 
    standarddeviation(edge,average); 
    return 0; 
}

這裏的錯誤是錯誤我得到：
