That's it, what is the char exactly used for in a program, to understand what someone puts in???

Like I mentioned, it depends. Perhaps you have a program where you need to iterate through a selection of letters from the alphabet to make a check as to whether a sentence contains certain values. For example, checking for vowels?

Otherwise if you have something like this, you can make it a char string:

Code:

int main()
{
    char * str = "string value";
}

You're using a pointer here as type char, but this enables you to use a string value.

Otherwise you can use string:

Code:

int main()
{
    string str = "my string";
}
