C++ :: Unable To Compare A String With A Char Pointer

Ok, I'm having a few problems with strings, mostly string functions saying they're not able to compare a string with a char pointer.

int main()
{
int counter = 0;
int x, y, z;

[Code].....

My goal is to take in a command and store it in a string. Different commands have different amounts of information I need. One command is "new flight <flightnumber> <seats available>". First, I try to understand which command is being asked, using the first character to decide. Once I can assume which command is being attempted, I try to separate the string into smaller strings (words) using strtok. I then compare the words that should be constant (new and flight), to make sure the command is syntactically correct (which I use strcmp for). Then I'll go on to create a new flight, which is a class that takes in a char * and integer (which is why I need to convert a char * to integer).
