extended initializer lists only available with
This style of initialisation, using braces:
int *multi = new int{7,3,9,7,3,9,7,3};
was introduced to the language in 2011. Older compilers don't support it; some newer ones (like yours) only support it if you tell them; for your compiler:
c++ -std=c++0x bankNum.cpp
However, this form of initialisation still isn't valid for arrays created with new
. Since it's small and only used locally, you could declare a local array; this doesn't need C++11 support:
int multi[] = {7,3,9,7,3,9,7,3};
This also has the advantage of fixing the memory leak - if you use new
to allocate memory, then you should free it with delete
when you've finished with it.
If you did need dynamic allocation, you should use std::vector
to allocate and free the memory for you:
std::vector<int> multi {7,3,9,7,3,9,7,3};
Beware that your version of GCC is quite old, and has incomplete support for C++11.

I'm very new to C++ and I'm having trouble reading my errors I was able to eliminate most of them but I'm down to a few and I'm request help on them please.
Here is the program
#include <string> #include <iostream> using namespace std; int main(){ int *bN = new int[9]; string bankNum; int *number = new int[9]; int total, remain; int *multi = new int{7,3,9,7,3,9,7,3}; cout<<"Please enter the bank number located at the bottom of the check"<<endl; cin>>bankNum; for(int i = 0; i < 8; i++){ bN[i]= (bankNum[i]-48); } for(int i = 0; i < 8;i++){ cout<<bN[i]; } cout<<endl; for(int i = 0; i < 8;i++){ cout<<multi[i]; } cout<<endl; for(int i = 0; i < 8;i++){ bN[i] = bN[i] * multi[i]; cout<< bN[i]; } cout<<endl; for(int i = 0; i < 8;i++){ total += bN[i] cout<<total; } cout<<endl; remain = total % 10; if(remain == (bankNum[9] - 48)){ cout<<"The Number is valad"<<endl; cout<<remain<<endl; } }
and the errors
