1. The c_str() and strcpy() function in C++ C++ c_str() function along with C++ String strcpy() function can be used to convert a string to char array easily. The c_str() method represents the sequence of characters in an array of string followed by a null character (‘\0’). ...
We can check the class of our vector with the class function:class(vec) # Check class of vector # "character"The RStudio console shows the data type of our vector: It’s a character. Now, we can use the as.factor function to convert this character string to the factor class:...
