Problem with variable char values

[forceface]

i wanted to be able to change the value of a char based on user input. I am not sure how to achieve this. Below is the section of code I am trying to achieve this in.

  char title_name[50];

if(front_or_back == 0){
 choose = 0;
 title_name[0] = "f";
 title_name[1] = "r";
 title_name[2] = "o";
 title_name[3] = "n";
 title_name[4] = "t";
}
else {
choose = 50;
 title_name[0] = "b";
 title_name[1] = "a";
 title_name[2] = "c";
 title_name[3] = "k";
}

I have also tried

  char title_name[50];

if(front_or_back == 0){
 choose = 0;
 title_name[] = "front";
}
else {
choose = 50;
 title_name[] = "back";

}

The value front_or_back is decided real time by the user. Any advice would be great, thanks.

The easiest way to do this is to use a string instead of a char array:

string title_name;
if(front_or_back == 0)
{
    choose = 0;
    title_name = "front";
}
else
{
    choose = 50;
    title_name = "back";
}

Or if you must use char arrays... note that a char array must be end with a null terminator (ie, character 0). This signifies the end of the string data.

So your first approach was close:

  char title_name[50];

if(front_or_back == 0){
 choose = 0;
 title_name[0] = 'f';  // <- 'single' quotes instead of "double" quotes
 title_name[1] = 'r';
 title_name[2] = 'o';
 title_name[3] = 'n';
 title_name[4] = 't';
 title_name[5] = 0;  // <- null terminator
}

Of course... that's very clunky and unwieldly. A better way is to use the strcpy function to set the string data:

  char title_name[50];

if(front_or_back == 0){
 choose = 0;
 strcpy(title_name,"front");
}

Thank you very much.
