    Need help in file processing output

    thanks for those who helped me.
    i have another problem but this time i have an output but incorrect character.
    i have a text file(note pad) containing this sentence:
    "stay extending from ship's mastheads to the side of the ship" but the result is incorrect.
    this is my code:
    #include <stdio.h>
    #include <conio.h>
    #include <string.h>
    #include <windows.h>
    FILE *fp2;
    char nword[15];
    int c, num2;
    printf("Enter a word:\t");
    c = strcmp(nword, "aba");
    if (c == 0)
          fp2 = fopen("def.txt", "r");
          num2 = fgetc(fp2);
          while(num2 != EOF) 
                      while(((num2 = fgetc(fp2)) != '1') && ((num2 = fgetc(fp2)) == '\n'));

    What exactly is your while condition trying to do?

    For a start, you call fgetc() TWICE (or maybe only once), depending on whether the first part of the condition evaluates to true or false.

    while ( (ch=fgetc(fp)) != EOF ) {
      if ( ch == something ) {
    Your loop should have ONE unconditional file read per iteration of the loop. If you need to do other things with ch, then put them inside the loop.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    my first while loop is for reading all the characters in the text file and the another (do while) is for viewing my desire line in the notepad.

    where will i place the loop?
