integer array element with leading 0 showing garbage output

i have this small piece of code that has an integer array containing some elements with a leading 0.

int arr[]={012,234,071};
cout<<arr[0]<<endl; //output 10
cout<<arr[1]<<endl; //output 234
cout<<arr[2]<<endl; //output 57

for some reason am i getting different output for values with leading zeros,can someone explain this to me why is this happening?

integer array element with leading 0 showing garbage output

You do not get "garbage" values; the compiler mainly interprets the values in your array that have leading zeros, like 012, as octal values. The compiler then converts it into a decimal value (for 012, it is 10) and outputs that.

Don't use leading zeroes if you are working with the decimal system.

Numeric literals with leading zeros are assumed to be octal numbers. Don't use leading zeros.
