/*Printing the sum*/

}

{

int i; //Variable declaration
float total=0.0; //the variable total is set to 0.0
for(i=0; i<n; i++) //Iterations
total+=x[i]; //each element x[i] is added to the value of total
return(total); //Returning the total value
}

Output:
Enter the number of elements in array
5
Enter 5 elements
14 15 16 17 18
The elements of array are:
14.00 15.00 16.00 17.00 18.00
Sum of the given array is: 80.00
