A Very Big Sum

  • mraemiller + 8 comments

    I tried it in pure C ...a world of pain! But here's the answer

    int main(){ int n; long bign = 0; long bignn; scanf("%d",&n); long arr[n]; for(int arr_i = 0; arr_i < n; arr_i++){ scanf("%li",&arr[arr_i]); } for(int arr_i = 0; arr_i < n; arr_i++){ bign = bign + (arr[arr_i]) ; } printf("%ld\n", bign); return 0; }

        Here's my code in C

        #include<stdio.h>
long aVeryBigSum(long long int ,int);
int main()
{
    int n,i;
    long long int p;
    scanf("%d",&n);
    long long int arr[n];
    for(i=0;i<n;i++)
    {
        scanf("%lld",&arr[i]);
    }
    p=aVeryBigSum(arr,n);
    printf("%lld",p);
}
long aVeryBigSum(long long int arr,int n)
{
    long long int sum=0,i;
    for(i=0;i<n;i++)
    {
        sum+=arr[i];
    }
    return sum;
}

      What's the reason for using two loops and an array? I feel like that just takes too much time and too much space. Here's my take in C if anyone's interested:

      #include <stdio.h>

int main(void){
    int n;
    long sum=0;
    scanf("%d", &n);
    long value;
    //long arr[n];
    for (int i=0; i < n; i++) {
        scanf("%li", &value);
        sum += value;
    }
    printf("%li", sum);
    return 0;
}

            Try long long int in place of int if you are using c

          • satyamskillz + 0 comments

            take value as value[] it will surly work.

        but if we intializing array in long type after then we are inputing it and summing it then it is showing runtime error.. can you tell me why this happening or i am wrong??

        I want to use functions in it . Can you give me the idea of it.

        It will only run for numbers less than 10 digit not more than that.

      "a world of pain" - completely agree with you.

    • nikhil_lagwanka1 + 0 comments

      Does this work if you put the sum part under that function they have provided
