I have a group of business days in format 'mm/dd/yyyy', from this, I created an array with a char format ( data_char) and a string format ( data_string). I have another much smaller group of dates also presented in two arrays with char ( date_vector_char) and string ( date_vector_str) formats. I want to know how many dates from the second group are present in the first group, and get their indices with a loop.
Without writing the loop, what I intend to do is this:
But the outcome is an empty array. When I hardcode a date value into the strcmp function, I get an index, but if I pick one value of my array, I get nothing.
Why is this? Can somebody help me? Thanks for your time.
