[NoWeDoR]

I wrote a program in C/Linux but as in the picture I have an issue. How can I solve this?
Thanks for helps.

My codes are:


#include <stdio.h>

int main()
{
FILE *ptrFILE;
int lineNumber = 1, choice, i, totalLineNumber;
char c;

if ((ptrFILE = fopen("Test.txt", "r")) == NULL)
{
printf("File couldn't open..\n\n");
}

printf("*-* Content of file *-*\n\n");
c = fgetc(ptrFILE);
while (!feof(ptrFILE))
{
printf("%c", c);
if (c == '\n')
{
lineNumber++;
}
c = fgetc(ptrFILE);
}
printf("\n\nTotal line number : %d\n\n\n\n", lineNumber);
totalLineNumber = lineNumber;

printf("Express the line number which you want to display (Enter positive value for at\nthe beginning or vice versa) : ");
scanf("%d", &choice);
printf("\n");
if (choice > 0)
{
lineNumber = 0;
fseek(ptrFILE, 0L, SEEK_SET);
c = fgetc(ptrFILE);
while (!feof(ptrFILE))
{
printf("%c", c);
if (c == '\n')
{
lineNumber++;
if (lineNumber == choice)
{
break;
}
}
c = fgetc(ptrFILE);
}
printf("\n\n\n");
}
else if (choice < 0)
{
lineNumber = 0;
fseek(ptrFILE, 0L, SEEK_SET);
c = fgetc(ptrFILE);
while (!feof(ptrFILE))
{
if (c == '\n')
{
lineNumber++;
}
if (lineNumber>totalLineNumber + choice)
{
printf("%c", c);
}
c = getc(ptrFILE);
}
printf("\n\n\n");
}

fclose(ptrFILE);
return 0;
}
