Hello, everybody, I have written prity long code and I think it is correct.

Question

https://code.sololearn.com/cHd9Nb17hOQ0/?ref=app
But trouble is I do not know how to remove special chars and extra whitespaces from string arrays str3[], which represent the addresses.
string str1[] are names of phone directory
string str2[] are phone numbers
string str3[] are addresses.

Answer 1

if character is not --alphabet Or number Or space --" remove it or don't copy into new one..

you can use isalnum() function to determine if character is alpha-numeric or not. For space, you can compare directly and use it if next character is not also space.
Hope it helps...
