Cannot convert float to float

[roverzon]

The compiler shows the error of cannot convert float to float at line 1.

I don't know what's going on about this error.

It is an easy program for calculating a distance between two point

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

void Distance(float p1[],float p2[]); 

int main(){
    float p1[3] = { 0, 0 ,0 };     
    float p2[3] = { 3, 4 ,0 };
    float dis;  
    
    dis = Distance(p1,p2); 
    
    printf("%f", dis); 
    
    system("pause"); 
    return 0; 
}

void Distance(float p1[],float p2[]){
    float delta[3] ={0};
    float del_square =0;  
           
    for (int i = 0; i < 3; i++){
        delta[i] = p1[i] - p2[i]; 
    }
    
    for(int i = 0; i < 3; i++){
        del_square += delta[i] * delta[i]; 
    } 
    
    return sqrt(del_square); 
}

This code:

dis = Distance(p1,p2);

assigns the return value from Distance to dis. But Distance returns a void (which means it returns nothing). So the complier complains it cannot convert void to float.

Also please use code tags.
