How to read a file in C but not to count with the header in the counter?

Question

FILING CABINET

The first line is the header I want to disregard. So that the counter "num" does not start counting from the HEADER

Answer 1

see if that’s what you’d like done:

What I changed was to include if(num != 0) to present on the screen and then write to your file, so it reads/writes anything other than line 0;

Another point, be careful because you are using C++ applications in your code as long as it works, but it is not very elegant...

I hope it helped. Hugs!!

#include <stdio.h>
#include <stdlib.h>
#include <locale.h>
#include <unistd.h>

int main(){
FILE * input_text, *output_text;
char line[1024];
char * last;
int num = 0;
setlocale(LC_CTYPE,"");
    if((input_text = fopen("entrada03.txt","r")) == NULL)
        printf("\n[ERRO]Travou o Nintendo!\n");
    else
        printf("\n[SUCESSO]Sucesso ao abrir o arquivo!\n\n");
    printf("\n\nImprimindo a saida\n\n");
    sleep(2);
    output_text = fopen("saida02.txt","w");

        while(!feof(input_text)){
            fgets(line, 1024, input_text);
                last = strtok(line, "\n");                                  //"last" recebe variável "line" até o delimitador "\n"
                    while(last != NULL){                                    //Se last não for "NULL" executa essa
                        if(num != 0)
                        printf("%d: %s\n",num, last);
                            last = strtok(NULL, "\n");                      //Se last for "NULL" até o delimitador "\n"
                            if(num != 0)                      
                            fprintf(output_text,"%d: %s\n", num, line);
                    }
                num++;
        }
fclose(input_text);
fclose(output_text);
printf("\n");
system("pause");
