Printf() not displaying as it should.
Hi, I have some code. Everything works as it should, but, when I call view_all_contacts() to print the data, each line doesn't line up as it should. I get tab keys between each line.



The problem code is this:

Code:
        printf("\n\e[1;34mNAME   :  \e[0;37m%s\n",name1);
        printf("\e[1;34mMOB NO. :  \e[0;37m%s\n",mob);

Here is the rest of the code:



Code:
void add_contact();
void search_contact();
void delete_contact();
void view_all_contact();

void add_contact()
{
    FILE *fp;
    fp=fopen("contact.txt","a+");
    printf("\e[20;10H\e[1;34mName     : \e[0;37m" );
    char name[20];
    scanw("%s",name);
    printf("\e[21;10H\e[1;34mMob No.  : \e[0;37m" );
    char mob[20];
    scanw("%s",mob);
    fprintf(fp,"%s %s ",name,mob);
    fclose(fp);
}
void search_contact()
{
    FILE *fp;
    fp=fopen("contact.txt","r");
    printf("\e[20;10H\e[1;34mSearch   : \e[0;37m");
    char name[20];
    scanw("%s",name);
    char name1[20],mob[20];
    while(fscanf(fp,"%s %s",name1,mob)!=EOF)
    {
        if(strcmp(name,name1)==0)
        {
            printf("\e[20;10H\e[1;34mNAME     : \e[0;37m%s\n",name1);
            printf("\e[21;10H\e[1;34mMOB NO.  : \e[0;37m%s\n",mob);
        }
    }
    fclose(fp);
}
void delete_contact()
{
    FILE *fp,*fp1;
    fp=fopen("contact.txt","r+");
    fp1=fopen("temp.txt","w");
    printf("\e[20;10H\e[1;34mEnter Name : \e[0;37m");
    char name[20];
    scanw("%s",name);
    char name1[20],mob[20];
    while(fscanf(fp,"%s %s",name1,mob)!=EOF)
    {
        if(strcmp(name,name1)==0)
        {
            continue;
        }
        fprintf(fp1,"%s %s\n",name1,mob);
    }
    fclose(fp);
    fclose(fp1);
    fp=fopen("contact.txt","w");
    fp1=fopen("temp.txt","r");
    while(fscanf(fp1,"%s %s",name1,mob)!=EOF)
    {

        fprintf(fp,"%s %s\n",name1,mob);
    }
    fclose(fp);
    fclose(fp1);
    remove("temp.txt");
}
void view_all_contact()
{
    FILE *fp;
    fp=fopen("contact.txt","r");
    char name1[20],mob[20];
    while(fscanf(fp,"%s %s",name1,mob)!=EOF)
    {
        printf("\n\e[1;34mNAME   :  \e[0;37m%s\n",name1);
        printf("\e[1;34mMOB NO. :  \e[0;37m%s\n",mob);
    }
    fclose(fp);
 }

Can someone tell me what is wrong with the code? Thanks for your time.

fclose

FCLOSE(3)						   BSD Library Functions Manual 						 FCLOSE(3)

NAME

     fclose, fcloseall -- close a stream

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <stdio.h>

     int
     fclose(FILE *stream);

     void
     fcloseall(void);

DESCRIPTION

     The fclose() function dissociates the named stream from its underlying file or set of functions.  If the stream was being used for output,
     any buffered data is written first, using fflush(3).

     The fcloseall() function calls fclose() on all open streams.

RETURN VALUES

     Upon successful completion 0 is returned.	Otherwise, EOF is returned and the global variable errno is set to indicate the error.	In either
     case no further access to the stream is possible.

ERRORS

     The fclose() function may also fail and set errno for any of the errors specified for the routines close(2) or fflush(3).

NOTES

     The fclose() function does not handle NULL arguments; they will result in a segmentation violation.  This is intentional - it makes it easier
     to make sure programs written under FreeBSD are bug free.	This behaviour is an implementation detail, and programs should not rely upon it.

SEE ALSO

     close(2), fflush(3), fopen(3), setbuf(3)

STANDARDS

     The fclose() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

     The fcloseall() function first appeared in FreeBSD 7.0.
