I've really only programmed with C++ and not C so far, and can't find out how to clear a string in C. I have tired using clear() and erase() but get the following error message:
"error: request for member ‘erase’ in something not a structure or union"
error: request for member ‘clear’ in something not a structure or union"
Can someone please help? Thanks.
First, why do you want to erase a string?
Set the first character to '\0'.

I am writing a simple calculator using GTK and one of the buttons is clear, which is supposed to do just that. I am using strings to get the numbers and also to display the result.
Code:#include <stdio.h> #include <string.h> int main() { char str[80]; strcpy( str, "Hello World" ); puts( str ); str[0] = '\0'; /* Clear the string. */ puts( str ); return 0; }
