help me to read data
I don't know where, but seems my code is wrong.
this is my input:
6 92 86 78 93 22 56
4 90 83 85 58
the first number indicates the total set of data
and also what if I have a lot set of data ?

The first error that the compiler shall issue is that variables a and b were not declared.
while (!input.eof())
{
read_data(a, b, input);
