    need help 4

    Hello again. Logic error

    my input file:
    !!Begin
    Source bserver:bmp_spool:the, Job 80c481ac001f6b07, Inst 80c481ac001f6b07
    Title BP Page 003 Date 070402 Black 3
    Action Finished Transmit, Ok Date Fri Apr 5 00:02:05 SGT 2002
    (2) Source Queue = Ajil_Tabloid
    (1) Destination = ajil:ajil1:bmp_spool:the
    (3) Dest Queue = Futuro Tabloid
    Transmitting to ajil:ajil1:bmp_spool:the
    !!End


    my source code:

    #include <stdio.h>
    #include <string.h>

    void main( void )
    {
    FILE *out;
    FILE *in;
    char line[80]=" ";
    char line2[8]="!!Begin";
    char line3[7]="";
    char line4[8]="!!End ";



    out=fopen("pxo.txt","w");
    in = fopen( "px.txt", "r" );
    while ((fgets(line,sizeof line,in)) != NULL)

    {


    printf( "%s", line);
    //line[strlen(line -1)]='\0';
    strncpy(line3,line,7);
    line3[7] = '\0';

    if (strcmp (line3,line4)== 0 )

    printf("Hello success\n");
    else
    printf("ooooo\n");


    }
    fclose( in );
    fclose( out );


    }


    when my program read last line "!!End" why it cannot say output
    "Hello success"?

    1.
    Use code tags.

    2.
    Use int main instead of void main.

    3.
    You declared

    char line3[7]="";

    So the last element is line3 [6], since the first element is line3 [0].
