Thanks in advance

using namespace std;

int main() {
int n;
cin >> n; //size of the array
//your code goes here
int nums[n];
int s = 0;

for (int d = 0; d < n; d++) {
cin >> s;
nums[d] = s;
}

int max = nums[0];
for (int i = 0; i < n; i++) {
if (nums[i] > max) {
max = nums[i];
}
}
cout << max;

return 0;
}

Answer 1

To be more compatible, you can use dynamic memory allocation approach for creating the array <num>, given a size.

Answer 2

You are using VLA which is not an official feature of the C++ language. Some compilers have it as extension but it doesn't mean a VLA based code be guaranteed to run (compilable) in any compiler, that includes one that came with (or as extension in) VSC.

Soloearn uses Gcc 10.2 compiler...

Preffered to use vector.
But if you want, try these :
