What is the output for the given program?
int sum(int arr[], int n)
{
int sum = 0;
for (int i = 0; i < n; i++)
sum += arr[i];
return sum;
}
main()
{
int arr[] = {12, 30, 40, 15};
int n = sizeof(arr) / sizeof(arr[0]);
cout << sum(arr, n);
return 0;
}
int sum(int arr[], int n)
{
int sum = 0;
for (int i = 0; i < n; i++)
sum += arr[i];
return sum;
}
main()
{
int arr[] = {12, 30, 40, 15};
int n = sizeof(arr) / sizeof(arr[0]);
cout << sum(arr, n);
return 0;
}
Correct answer is '97'. Can you explain this answer?

What is the output for the given program?int sum(int arr[], int n){int...
The given program is incomplete and does not provide a clear output. It is missing the closing curly brace for the for loop and the main function.
To get a valid output, we need to complete the program. Here's an example of a completed program that calculates the sum of an array:
```c++
#include
int sum(int arr[], int n) {
int sum = 0;
for (int i = 0; i < n;="" i++)="" />
sum += arr[i];
}
return sum;
}
int main() {
int arr[] = {1, 2, 3, 4, 5};
int n = sizeof(arr) / sizeof(arr[0]);
int result = sum(arr, n);
std::cout < "sum="" of="" array="" elements:="" "="" />< result="" />< />
return 0;
}
```
Output:
```
Sum of array elements: 15
```

What is the output for the given program?int sum(int arr[], int n){int...
The program is described as:
In the given code, Consider the address of the array as 100.
The main function has an array arrr[] = {12, 30, 40, 15};
int n = sizeof(arr) / sizeof(arr[0]);
sizeof(arr) = 16(4 x 2) i.e four elements and each size is 2.
sizeof(arr[0]) = Size of element arr[0] i.e first element size = 2.
So n becomes n=16/2
∴ n=4
And sum(arr, n)
Here arr is the address of the array.
sum(100, 5)
The main function has an array arrr[] = {12, 30, 40, 15};
int n = sizeof(arr) / sizeof(arr[0]);
sizeof(arr) = 16(4 x 2) i.e four elements and each size is 2.
sizeof(arr[0]) = Size of element arr[0] i.e first element size = 2.
So n becomes n=16/2
∴ n=4
And sum(arr, n)
Here arr is the address of the array.
sum(100, 5)
The sum function calculates the summation of elements
Initially, the sum=0 sums each element and stores it in the sum variable.
sum=12+30+40+15
sum=97 and returns the sum variable to the main function i.e 97.
Hence the correct answer is 97.
