Array strings C++

Question

I don't remember how to do this in C++:

#include <iostream>
#include <conio.h>
#include <string.h>

int main(){
    char categorias[3][20];
    /*char pais[3][20];
    char movimiento[3][50];
    char obras[100][50]; */

    categorias[0]="Alta";
    categorias[1]="Media";
    categorias[2]="Baja";
}

This throws this error: 19 15 C:\Users\dell\Desktop\Subasta.cpp [Error] incompatible types in assignment of 'const char [5]' to 'char [20]';

Long time ago I don't use C++ and I can´t solve the problem.

Use std::string instead of char[] and your life will be much easier. — Yksisarvinen

This isn't array of strings but array of characters. To copy to an array of characters use strcopy or something. Though, I advise to use std::array<std::string,3> categorias instead of char[3][20]. — ALX23z

Note that Dev C++ is an IDE and not a compiler. I assume you are using some version of mingw. — drescherjm

main(){ in c++ you should not omit the int before main. — drescherjm

categorias[0]="Alta"; c-strings are not assignable. Replace char categorias[3][20]; with std::string categorias[3]; and the assignment will work. — drescherjm

Use C++ abstractions and containers from the standard library:

int main()
{
    using namespace std::string_literals;

    auto categorias = std::vector{"Alta"s, "Media"s, "Baja"s};

    // Or if you know you have a fixed number of categories:
    auto categorias = std::array{"Alta"s, "Media"s, "Baja"s};
}

To copy the string literal into the char array

strcpy(categorias[0], "Alta");
