A simple yet confused query

[naveenpadmadas]

Hi,
i have a simple query. I was practising a c program using function by just calling the function. The called function are defined with only printf statements. I tried executing the same program in different desktops having the same configuration.When i execute the program, in some machines, am getting an error message "function should have a prototype", meanwhile some desktops are giving me the output. Can anyone say please what can be the error. since i am not passing any values to the function, am confused how to declare the prototype. Please help me.
regards,
naveen

You posted your question in the wrong section; I'll move your question to the C/C++
Forum section.

Add the prototype like this:

void theFunc(void);

Add the prototype like this:

void theFunc(void);

if a function is void, it means it doesn't return anything.

this is the declaration of the function:
void function(void).
but when you call it:
function();

thanks;
