我的代码计算两个数字的总和和平均值，在执行和编译时返回此错误“[Error] ld returned 1 exit status”

Question

This is my code. I've read the output log but can't see where the exact error is; I will appreciate if someone can kindly point me to it. The IDE I'm using is Dev C++.

int main(){
    int n, i, a, average, sum;
    printf("enter the number of integers to be picked\n");
    scanf("%d", n);
    
    sum=0;
    printf("Enter a number.");
    scanf("%d", &a);
    
    for (i=0; i<=n;i++){
        printf("%d", i);
        sum=sum + a;
    }
    average=sum/n;
    printf("The average is %d", average);
    return 0;
}

Answer 1

You're just missing the & (address-of operator) in line 4 ( scanf("%d",&n); ). Putting this operator will tell the compiler, the address of n , where the value of n will be kept.
