Line 38:
The problem with the usually specified function is that the term <code>5*t^3</code> gives overflows in almost all languages for very large negative values.
==[[C++]] implementation==
This shows a C++ implementation equivalent to the above ALGOL 60. Evolution of C++98, C++11 and C++14 is showed as well.
<syntaxhighlight lang="cpp">
#include <algorithm>
#include <cmath>
#include <iostream>
double f(int n) { // in C++14, return type can be inferred using "auto f(int n)"
return sqrt(abs(n)) + 5*n*n*n;
}
int main() {
const int N = 11; // in C++11, can be declared as "constexpr auto N = 11;"
int S[N]; // in C++11, can be declared as "std::array<int, N> S;
for(int i = 0; i < N; ++i) {
std::cin >> S[i];
}
std::reverse(S, S+N); // in C++11, can be used as "std::reverse(begin(S), end(S));"
for(int i = 0; i < N; ++i) { // in C++11, can be used as "for(auto i : S) {"
double y = f(i);
if(y > 400) {
std::cout << i << " TOO LARGE\n";
}
else {
std::cout << y << '\n';
}
}
}
