Conversion from string to char - c++
Solution 1
You can get a specific character from a string simply by indexing it. For example, the fifth character of str
is str[4]
(off by one since the first character is str[0]
).
Keep in mind you'll run into problems if the string is shorter than your index thinks it is.
c_str()
, as you have in your comments, gives you a char*
representation (the whole string as a C "string", more correctly a pointer to the first character) rather than a char
.
You could equally index that but there's no point in this particular case.
Solution 2
you just need to use value[0] and that returns the first char.
char c = value[0];

I'm a student at the University of Kentucky pursuing a Computer Science degree. I'm told that I have a brilliant mind, but I don't always have the knowledge for implementing my ideas. I'm a visual learner and learn by example. I developed a passion creating things out of nothing at a young age. I began teaching myself web design in the fourth grade. I continued to develop my web design skills through middle school before venturing from HTML. I taught myself basic PHP programming, which influenced me to take a CS class in high school. I fell in love with the idea of programming and decided to pursue a CS career. I struggle with certain areas in programming, but still use PHP and web design as a form of relaxation. I've make countless websites and love implementing things I haven't done before.

For a program I'm writing based on specifications, a variable is passed in to a function as a string. I need to set that string to a char variable in order to set another variable. How would I go about doing this?
This is it in the header file:
void setDisplayChar(char displayCharToSet);
this is the function that sets it:
void Entity::setElementData(string elementName, string value){ if(elementName == "name"){ setName(value); } else if(elementName == "displayChar"){ // char c; // c = value.c_str(); setDisplayChar('x');//cant get it to convert :( } else if(elementName == "property"){ this->properties.push_back(value); } }
Thanks for the help in advanced!
