Count number of lines in the file

Question

Good morning,this function counts the number of lines of a file,but it has a little problem,it only counts the line when it finds the n,for example to test it,I would create a text file,and write a word to see if it was ok,And then I went to find out that it didn’t count because I hadn’t entered at the end of the word and so she couldn’t find the number,can someone else tell me how to count the number without having to worry about giving a word a enter? Function code:

char numerolinhas(){
    char contar;
    int linhas=0;
    FILE *file;

    file=fopen("Frutas forca.txt","r");

    char conta;
    while((conta=fgetc(file))!=EOF){
        if(conta=='\n'){
        linhas++;
        }
    }
    fclose(file);

    return linhas;

Answer 1

Your problem is the definition of "line".

Normally a line is defined by "a sequence of (0 or more) characters terminated by, and including, one end-of-the-line".

In some cases it can also be defined by "a sequence of (0 or more) characters separated by a end-of-the-line (or EOF) not belonging to the line".

In the first case the end-of-line is part of the line, in the second case not.

Your program uses the first line definition, but the file you use was created with the second definition.

Solution 1) changes the file to meet the line definition used by the program

Solution 2) changes the program to accept the second line definition.

An empty file (0 bytes) how many lines it has?
definition 1) 0 lines; definition 2) 1 line (empty)

A file with an X (1 byte) how many lines it has?
definition 1) 0 lines (1 "loose" character); definition 2) 1 line (with "X")

A file with a ENTER (1 byte) how many lines it has?
definition 1) 1 line (empty, ie only with ENTER); definition 2) 2 lines
