Array of symbolic pointers, cannot compile

[yiddo]

Hey guys. I wanted to try the exercise Array of symbolic pointers. It seems i am missing something for my array. I need second opinion.

#include <iostream>
#include <cstdlib>
using namespace std;
int main ()
{
    char *str[3]={{"red"},{"yellow"},{"white"}};
    for(int i=0; i<3; i++)
    {
        cout<<str[i]<<endl;
    }
    cout<<str[2][0]<<str[0][4]<<str[1][0];
    cout<<str[2][3]<<str[0][3]<<str[1][4]<<endl;

    system("pause");
    return 0;
}

That does exactly what you are asking it to?

str[2][0] == white string first char
str[0][4] == red string past end(highest is [2]
str[1][0] == yellow string first char
str[2][3] == white string fourth char
str[0][3] == red string past end(highest is [2]
str[1][4] == yellow string 5th char

hope this helps

I had to be exact here, sorry for that. CodeBlocks gives me some problem at line 6.

compiled fine for me but im using MVS community

[37oyvCM9]

whats the error?

[yiddo]

That's actually helpful. I guess the code is not the problem. Hmm. I plan to use MVS for C# i guess i will add the C++ option on it as well. CodeBlocks is not kind to me all the time.

Thank you very much, guys !

1. const needed (the type of a narrow string literal is array of const char)
2. In the braced-init-list omit braces around the initialiser for a scalar.

// char *str[3]={{"red"},{"yellow"},{"white"}};
const char* str[3] = { "red", "yellow", "white" } ;

JLBorges. This actually worked fine! "const" wasn't a must, but the braces change did the thing.
Thanks, mate!

> "const" wasn't a must

With a conforming compiler, const is a must.

To force the GNU compiler to conform to standard C++ (to the extent that it is capable of conforming),
compile with -std=c++14 -pedantic-errors

int main ()
{
    char *str[3]={ "red", "yellow", "white" };
}

LLVM clang++: error: ISO C++11 does not allow conversion from string literal to 'char *'
GNU g++: error: ISO C++ forbids converting a string constant to 'char*'
