Issue with Arrays in Xcode

alexrwilson (2)
I have been using a textbook to learn a bit of C++. The below code is an exact copy of what the textbook says to code, but the program will not build. Arrays only seem to work if i declare 'then' initialise as opposed to declare 'and' initialise which is a problem when the array is an axis of coordinates as it would take forever to type each possibility out individually. Other programs i have copied from the book build and work normally.

Have i set Xcode up wrong or something?

#include <iostream>
using namespace std ;


int main ()

{

float nums[3] ;
nums [0] = 1.5 ; nums[1] = 2.75 ; nums[2] = 3.25 ;

char name[5] = [ 'M','i','k','e', '\0' ]

int coords[2][3]; coords[2][3] = {{1,2,3},{4,5,6}} ;


}

cout<<"nums[0]:"<<nums[0]<<endl ;
cout<<"nums[1]:"<<nums[1]<<endl ;
cout<<"nums[2]:"<<nums[2]<<endl ;
cout<<"nums[0]:"<<nums[0]<<endl ;
cout<<"Text string: "<<name<<endl;
cout<<"coords[0][2]:"<<coords[0][2]<<endl;
cout<<"coords[1][2]:"<<coords[1][2]<<endl:

char name[5] = [ 'M','i','k','e', '\0' ]

int coords[2][3]; coords[2][3] = {{1,2,3},{4,5,6}} ;


}

cout<<"nums[0]:"<<nums[0]<<endl ;
cout<<"nums[1]:"<<nums[1]<<endl ;

cout<<"Text string: "<<name<<endl;
cout<<"coords[0][2]:"<<coords[0][2]<<endl;
cout<<"coords[1][2]:"<<coords[1][2]<<endl:

The final brace in line 17 is wrong. It should be after line 25.

Line 12 is wrong too. It should be char name[5] = { 'M','i','k','e', '\0' };.

Now about line 14... You can only initialize arrays like that on definition, so it should be only int coords[2][3] = {{1,2,3},{4,5,6}} ;

In the end of line 25, it's expected a ; instead of :.
