How to add a new line in a text file?
I have a few lines of code:
strcat(myTxt,"data");
strcat(myTxt,"\n");
strcat(myTxt,"data1");
In between the lines 开发者_JAVA百科I've done strcat
of "\n"
; however, when I do a write to a text file the "\n"
is ignored and all the strings are concatenated as datadata1
. How can I work around this issue?
This code works for me:
#include <string.h>
#include <stdio.h>
int main ()
{
char myTxt[100];
myTxt[0] = 0;
strcat(myTxt, "data");
strcat(myTxt, "\n");
strcat(myTxt, "data1");
printf("%s\n", myTxt);
return 0;
}
Did you initialize the buffer's first byte? Edit: works also with a file as output:
#include <string.h>
#include <stdio.h>
int main ()
{
char myTxt[100];
FILE *out = fopen("out.txt", "wt");
myTxt[0] = 0;
strcat(myTxt, "data");
strcat(myTxt, "\n");
strcat(myTxt, "data1");
fprintf(out, "%s\n", myTxt);
fclose(out);
return 0;
}
For file output, you should do strcat of "\r\n"
