too few arguments to function in 'function()'

[deibaby03]

this is my function declaration

    int boygroups(int ans);

and this is my function definition

    int boygroups(int ans) {             
	switch (p) {
		case 1: printf("\n\n\n\t\t\t\t1. %s\n",songs[0].una);
			printf("\t\t\t\t2. %s\n",songs[0].pangalawa);
			printf("\t\t\t\t3. %s\n",songs[0].pangatlo);
			printf("\t\t\t\t4. %s\n",songs[0].pangapat); 
			break; 
		case 2: printf("\n\n\n\t\t\t\t1. %s\n",songs[1].una);
			printf("\t\t\t\t2. %s\n",songs[1].pangalawa);
			printf("\t\t\t\t3. %s\n",songs[1].pangatlo);
			printf("\t\t\t\t4. %s\n",songs[1].pangapat); 
			break;
		case 3: printf("\n\n\n\t\t\t\t1. %s\n",songs[2].una);
			printf("\t\t\t\t2. %s\n",songs[2].pangalawa);
			printf("\t\t\t\t3. %s\n",songs[2].pangatlo);
			printf("\t\t\t\t4. %s\n",songs[2].pangapat);      
			break;
		case 4: printf("\n\n\n\t\t\t\t1. %s\n",songs[3].una);
			printf("\t\t\t\t2. %s\n",songs[3].pangalawa);
			printf("\t\t\t\t3. %s\n",songs[3].pangatlo);
			printf("\t\t\t\t4. %s\n",songs[3].pangapat);       
			break; 
	
	}        
}

My declaration and definitioon is the same, i don't know why i keem getting an error like this.

show us how you call it.

(also, don't you want to return an int? If not, make it a void function)


edit: I see Mikey has answered your question in your other thread (http://www.cplusplus.com/forum/beginner/124653/)

boygroups(); <-- i call it like this, and then i have a value to return i just forgot to write it.

[mutexe]

Then that's the reason. You call it without passing in an int. but you've told your compiler your method will take an int.

But i can see this is being pointed out in your other thread.

i don't get it, i just forget to write the return value here, but it is written in my program.

This has nothing to do with the return value. You've defined your function to take an integer argument. But you're not supplying that argument when you actually call the function.

It seems to me that you really don't understand how to call functions with arguments. I recommend you go back to your textbook and re-read the section on functions, because this is of fundamental importance to writing C and C++ code, and you'll need to be sure you understand it.
