I'm trying to use the erase function to delete any ints from my vector with a value of 0.
void eliminateZeroes(std::vector<int> &answers){
auto i = answers.cbegin();
while(i != answers.cend()){
if(*i == 0){
i = answers.erase(i);
}else{
i++;
}
}
I expect the function to remove any items from the vector which are valued 0.
Error message:
/home/ec2-user/environment/DP378-Havel_Hakimi_-_Easy/main.cpp: In function ‘void eliminateZeroes(std::vector<int>&)’:
