too few arguments to function

Projects Programming

Hi everybody

I have a Problem with my actual Project.
I use a 4D system display and have implemented the user interface in Visi- genie.
Now I would like to evaluate the buttons from the keyboard and display on the display (LED digits) . I receive the error message " too few arguments to function" unfortunately I dont understand this message and dont know what to do . I hope you can help me with my problem . Many thanks in advance

The compiler is telling you that your code has a problem and it cannot compile.

You are trying to use a function but are not passing in to it all the required arguments (variables).

Example -- if we define foo like this....

void foo(int x, int y) {
do something interesting with x and y
}

...and then call it like this.....

foo ( 47 );

the compiler will say that I have "too few arguments..."

...what you need to have is....

foo ( 47, 99 );

The compiler may have indicated also the offending line number. Start there.

Enjoy.

Either call it with an argument or rewrite it so it doesn't take one.

Or give it a default value in case you forget to give it an argument.
