From me
===============================
Can you try 2 samples?
with delay
=================================================
#include <stdio.h>
#include <unistd.h>
int main()
{
double x;
for (x = 0.0; x <= 5.0; x += 0.1) {
printf("%f %f\n", x, x);
}
sleep(1);
return 0;
}
force a write from buffer to stdout
=================================================
#include <stdio.h>
int main()
{
double x;
for (x = 0.0; x <= 5.0; x += 0.1) {
printf("%f %f\n", x, x);
}
fflush(stdout);
return 0;
}
From Moshe Milshtein ===================================== Flushing or closing stdout does not help. My locale is en_US.UTF-8. Adding a delay after the loop with sleep(1) (as suggested by soldatov) solves the problem. Link to e-mail thread: https://netbeans.org/projects/cnd/lists/users/archive/2017-09/message/17 Hm. I can reproduce this bug in NetBeans 8.2 patch 2, but original NetBeans 8.2 works nicely. I see stable bug in NetBeans 8.2 patch 2 and NetBeans 8.2 original if I uses such code (50.0 instead of 5.0):
#include <stdio.h>
int main()
{
double x;
for (x = 0.0; x <= 50.0; x += 0.1) {
printf("%f %f\n", x, x);
}
return 0;
}

From Moshe Milshtein ===================================== I am using NetBeans 8.2 in Ubuntu 17.04 with gcc 6.3.0. I created a C project with the following code in main.c: #include <stdio.h> int main(void) { double x; for (x = 0.0; x <= 5.0; x += 0.1) printf("%f %f\n", x, x); } When running the project the loop is halting. Here is the end of the output that I see in the run window: 4.300000 4.300000 4.400000 4.400000 4.500000 4.500000 4.600000 4.600000 4.700000 RUN FINISHED; exit value 0; real time: 0ms; user: 0ms; system: 0ms If I open a terminal window and build the same source with "gcc main.c" the program gives the expected result, looping until 5.0000000. What's going on? Thanks.
