Printing values in a column (truth table)

I should have 5 columns for R, I0, I1, Out0, Out1 respectively.
Instead I have 8 columns and I dont understand where it is coming from..

Code:


#include <stdio.h>

void fsm1(char Reset,char I0, char I1,  char *Out0, char *Out1);
void fsm2(char Reset,char I0, char I1,  char *Out0, char *Out1);

int main(int argc, char *argv[])
{
    char I1,I0,Reset, Out1, Out0, i;



    printf("PIC Microcontroller\n\n");
    printf("Operations with Reset=0\n\n");
    printf("R   I0  I1  Out0   Out1\n\n");

    Reset=0;
    I0=0;
    I1=0;
    Out0=0;
    Out1=0;

    for(i=0;i<17;i++)
    {
        printf("%1d %1d %1d %1d %1d", Reset, I0, I1, Out0, Out1);
        fsm1(Reset,I0,I1,&Out0,&Out1);
        printf("%1d %1d %1d %1d \n",I0,I1,Out0,Out1);
    }

    printf("\n\n Operation with R=1\n\n");
    printf("R    I0  I1  Out0   Out1\n\n");

    Reset=1;
    I0=0;
    I1=0;
    Out0=0;
    Out1=0;

    int j;
    for(j=0;j<17;j++)
    {
        printf("%1d %1d %1d %1d %1d", Reset, I0, I1, Out0, Out1);
        fsm2(Reset,I0,I1,&Out0,&Out1);
        printf("%1d %1d %1d %1d \n",I0,I1,Out0,Out1);
    }

    printf("\n\n\n");
}

void fsm1(char Reset,char I0, char I1,  char *Out0, char *Out1)
{



    static char I0table[] = {0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1};
    static char I1table[] = {0,0,0,0,1,1,1,1,0,0,0,0,1,1,1,1};
    static char Out0table[] = {1,1,1,1,0,1,0,1,1,0,1,0,0,0,0,0};
    static char Out1table[] = {0,1,0,1,0,0,1,1,1,0,1,0,1,0,1,0};

    int index=(I0<<2)+(I1<<1)+(*Out0<<0)+*Out1;


    I0=I0table[index];
    I1=I1table[index];
    *Out0=Out0table[index];
    *Out1=Out1table[index];


}

void fsm2(char Reset,char I0, char I1,  char *Out0, char *Out1)
{



    static char I0table[] = {0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1};
    static char I1table[] = {0,0,0,0,1,1,1,1,0,0,0,0,1,1,1,1};
    static char Out0table[] = {1,1,1,1,0,1,0,1,1,0,1,0,0,0,0,0};
    static char Out1table[] = {0,1,0,1,0,0,1,1,1,0,1,0,1,0,1,0};

    int index=(I0<<2)+(I1<<1)+(*Out0<<0)+*Out1;


    I0=I0table[index];
    I1=I1table[index];
    *Out0=Out0table[index];
    *Out1=Out1table[index];


}

shouldn't you have a \n in your first printf? Otherwise the output from your 2nd printf will probably start on the same line making it look like you have more columns.

But you didn't fix the necessary feedback.
