抱歉，这段代码有语法错误，无法执行。其中有一些拼写错误，例如"Sarr"应该为"arr"，"scanf"语句中的引号应该去掉，"3分"应该为"arr"。此外，"float all"应该为"float a[]"，并且在函数内部需要对最大值和最小值进行更新。以下是修改过的代码：

#include <stdio.h> 

float minmax(float a[], int n, float *p, float *q); 

int main() {
    float arr[100], max, min, average;
    int n, i;
    scanf("%d", &n);
    for (i = 0; i < n; i++) {
        scanf("%f", &arr[i]);
    }
    average = minmax(arr, n, &max, &min);
    printf("average=%.2f, max=%.2f, min=%.2f\n", average, max, min);
    return 0;
}

float minmax(float a[], int n, float *p, float *q) {
    float sum = 0;
    *p = a[0];
    *q = a[0];
    for (int i = 0; i < n; i++) {
        sum += a[i];
        if (a[i] > *p) {
            *p = a[i];
        }
        if (a[i] < *q) {
            *q = a[i];
        }
    }
    return sum / n;
}
