  Objective This is a simple challenge to help you practice printing to  stdout . You may also want to complete  Solve Me First  in C++ before attempting this challenge. We’re starting out by printing the most famous computing phrase of all time! In the editor below, use either  printf  or  cout  to print the string  Hello ,World!  to  stdout . The more popular command form is  cout . It has the following basic form: cout<<value_to_print<<value_to_print; Any number of values can be printed using one command as shown. The  printf  command comes from C language. It accepts an optional format specification and a list of variables. Two examples for printing a string are: printf("%s", string);   printf(string); Note that neither method adds a newline. It only prints what you tell it to. Output Format Print   Hello ,World!   to stdout. Sample Output Hello, World! Solution:- //Say Hello, ...

1D Arrays in C Hackerrank Solution

 An array is a container object that holds a fixed number of values of a single type. To create an array in C, we can do int arr[n];. Here, arr, is a variable array which holds up to 10 integers. The above array is a static array that has memory allocated at compile time. A dynamic array can be created in C, using the malloc function and the memory is allocated on the heap at runtime. To create an integer array, arr of size n , int *arr = (int*)malloc(n * sizeof(int)), where arr points to the base address of the array.

In this challenge, you have to create an array of size  dynamically, input the elements of the array, sum them and print the sum of the elements in a new line.

Input Format

The first line contains an integer, n .
The next line contains n space-separated integers.

Constraints

1 < n < 1000

1 < ai < 1000

Output Format

Print in a single line the sum of the integers in the array.

Sample Input 0

6
16 13 7 2 1 12

Sample Output 0

51

Sample Input 1

7
1 13 15 20 12 13 2

Sample Output 1

76

Code

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

int main() {
    int n,a[1000],i,sum=0;
    /* Enter your code here. Read input from STDIN. Print output to STDOUT */    
    scanf("%d",&n);
        for(i=0;i<n;i++)
        {
            scanf("%d",&a[i]);
            sum=sum+a[i];
        }
    printf("%d",sum);
    return 0;
}
