int place = determinePlace(input);
const int arraySize = (place + 1);
int decimal[arraySize] = {};
Hi!
I tried to use a const int variable to define the array size of decimal[]. However, error C2057 and error C2466 keeps on coming up.
Are there any suggestions?
Even if you declare arraySize as const, it's still not a compile-time constant since it have to be calculated run-time.
Use std::vector instead:
std::vector<int> decimal(arraySize);
array size should be int , unsigned, unsigned int or size_t not a decimal type double
use std::vector
to use
#include <vector> // include the header
to define a vector
std::vector<int> vec = {1, 2, 3, 4, 5};
this defines vector int with a values of 1, 2, 3, 4, 5
to add some values
vec.push_back(12);
adds 12 to vec vector
Joachim is right, you are trying to set:
const int arraySize = (determinePlace(input) + 1);
this doesn't work, because you are trying to get a user input or something similar which will be only accessible when you run the program not when you compile it.
I would try something like this:
#include <vector>
using std::vector;
vector<int> decimal;
decimal.resize(determinePlace(input) +1);
decimal = {};
constexpr(but that probably won't work here, unlessdeterminePlaceis aconstexprfunction, andinputis aconstexpralso; which is very unlikely)
