Thread: inputting integer array in a row recursevly..

i need to enter an array in a row number so they will become an array
when i enter
1 2 3 4 5 6 7 8
it says debug assertion failed

why its not working??

Code:

#include <stdio.h>
int read_array(int input[],int i,int size);
 
int main()
{
    int input[40];
    printf("%d",read_array(input,0,8));
}
int read_array(int input[],int i,int size)
{
	int flag;
       
	if (i==size-1)
	{
     
	   return 1;
	}
     flag=scanf("%d",&input[i]);
	 if (flag==0)
	 {
		 return 0;
	 }
	 else
	 {
	 }
     read(input,i+1,size); 
}

i enter 1 2 3 4 5 6 7 8
ok it works
but i get a warning that not all path return value
i cant see what case i missed

Code:

 
#include <stdio.h>
int read_array(int input[],int i,int size);
 
int main()
{
    int input[40];
    printf("%d",read_array(input,0,8));
}
int read_array(int input[],int i,int size)
{
	int flag;
       
	if (i==size-1)
	{
     
	   return 1;
	}
     flag=scanf("%d",&input[i]);
	 if (flag==0)
	 {
		 return 0;
	 }
	 else
	 {
	 }
     read_array(input,i+1,size); 
}

but i get a warning that not all path return value
i cant see what case i missed

Are you joking? your function is 10 lines long and you can't see that?

Code:

     read_array(input,i+1,size); 
     // hint-of-the-day: function ends here
}

it need to end when i==size
or when the input is wrong

i dont need to return anything in the end except the recursive call
i changed the code so the recursive call will go to some variable
but the warning keeps showing
what case i missed??

Code:

 
#include <stdio.h>
int read_array(int input[],int i,int size);
 
int main()
{
    int input[40];
    printf("%d",read_array(input,0,8));
}
int read_array(int input[],int i,int size)
{
	int flag,rt;
       
	if (i==size-1)
	{
     
	   return 1;
	}
     flag=scanf("%d",&input[i]);
	 if (flag==0)
	 {
		 return 0;
	 }
	 else
	 {
	 }
     rt=read_array(input,i+1,size); 
}

i fixed it thanks

i put return rt in the end
and it worked fine
is there a problem with how i did it??

I suggest you get back to C programming basics before resuming this.

i dont need to return anything in the end

Sure. But your program tells otherwise and the compiler works on your program not on what you wish it should do.

i put return rt in the end instead of return 0
and it worked fine
is there a problem with how i did it??

as long as you return something, the compiler will be happy.
