dúvida relacionada a ponteiros e funções

Question

Olá, boa tarde. 

Estou com duvida sobre o porquê do meu código não rodar. Eu pesquisei na internet e aparentemente ele esta 100%, sem nenhum erro. 

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

void somatorioMedia(float *a, int n, float *somatorio, float *media);

int main(){
    int i;
    float a[10];
    int n = 10;
    float *somatorio;
    *somatorio = 0;
    float *media;
    *media = 0;

    for(i=0; i<10; i++){
        printf("n[%i]: ", i);
        scanf("%f", &a[i]);
    }
    somatorioMedia(a, n, somatorio, media);
    printf("Somatorio: %.2f\n", *somatorio);
    printf("Media: %.2f", *media);

    return 0;
}

void somatorioMedia(float *a, int n, float *somatorio, float *media){
    int i;
    for(i=0; i<n; i++){
        *somatorio += a[i];
    }
    *media = *somatorio / n;

}
