Question

How do I append a single char to a string in C? i.e ``` char* str = "blablabla"; char c = 'H'; str_append(str,c); /* blablablaH */ ```

Accepted Answer

```
char* str = "blablabla";     
```

You should not modify this string at all. It resides in implementation defined read only region. Modifying it causes Undefined Behavior.

You need a char array not a string literal.
