PROBLEM:

Given an array of integers [A1,A2,…An] you need to find sum of all other indices of the given array excluding the current one.

EXPLANATION:

Simply think that you need to find the number of candies that all other students have in your class the there are two different approaches…
  • Count for every student the number of chocolates and display it.
  • Alternatively, you can sum all the values together and display the sum excluding the sum of the present student. 
      #include "stdio.h"
	int main()
	{
	int t;
	scanf("%d",&t);
	while(t--)
	{
	int n;
	scanf("%d",&n);
	int a[n+1];
	long int sum=0;
	for(int i=0;i<n;i++) scanf("%d",&a[i]),sum+=a[i];
	for(int i=0;i<n;i++) (i==n-1)?printf("%ld\n",sum-a[i]):printf("%ld ",sum-a[i]);
	}
	return 0;
	}

    In C/C++ you can’t declare an array with a variable number of index.
    It uses static memory location (basic level).So error is due to the declaration of the array a[n+1].
    Declare the array with a numeric value.
