For eg: display(4) should print

Answer 1

The recursive function used here is func(int). Initially the value is passed from the main() program. The recursion occurs till we reach the exit condition , which is val=0 in this case. Once we reach that level , we move the penultimate frame a print "1". The same pattern is followed to attain the sequence "1 2". . . "1 2 3 " . . . "1 2 3 4"

int func(int val){

        int temp,i;

        if( val == 0 )
        {
                val++;
                return val;
        }
        else
        {
                val--;
                temp=func( val );

                for (i=1;i<=temp;i++)
                {
                        printf("%d",i);
                }
                printf("\n");

                temp++;
                return temp;
        }
}

int main(){

        int value=4, result;

        result=func(value);
}
