What are Strings

Sooo… I’ve learned about programming last year and I’ve become better since but I do not know what strings are and when it should be used in a program or it’s context in the equation… SOS

A string holds a sequence of characters, I forget the internal details but I think it is limited to 20. A better alternative is a char array,

task main()
    string str = "Hello";

    char str1] = "Goodbye";
