i want to print "CLIENT>" on stdout in c, without new line.
printf("CLIENT>");
does not print enything.
how do i solve this?
int main (){
printf("CLIENT>");
}
The printf statement does not automatically append a newline to its output. It outputs only what the format string specifies. So if a newline is needed, you must include one in the format string.
Puts automatically adds a new line at the end of your message every time you use it. If you don't want a newline, then use print .
The escape sequence \n means newline. When a newline appears in the string output by a printf, the newline causes the cursor to position to the beginning of the next line on the screen.
The new line character in Python is \n . It is used to indicate the end of a line of text. You can print strings without adding a new line with end = <character> , which <character> is the character that will be used to separate the lines.
Try fflush(stdout);
after your printf
.
You can also investigate setvbuf
if you find yourself calling fflush
frequently and want to avoid having to call it altogether. Be aware that if you are writing lots of output to standard output then there will probably be a performance penalty to using setvbuf
.
Call fflush
after printf()
:
int main (){
printf("CLIENT>");
fflush( stdout );
}
On some compilers/runtime libraries (usually the older ones) you have to call fflush to have the data physically written:
#include <stdio.h>
int main( void )
{
printf("CLIENT>");
fflush(stdout);
return 0;
}
If the data has newline in the end, usually fflush
isn't needed - even on the older systems.
