I have been trying to create a simple type writer effect in c. Have not been successful.
I figured it has to do with char and for, but I can't figure out how to do it.
Maby someone on here can help me write a simple type writer effect in c. The kind you see in rpg and other games.
Thanks.
and what do you call type writer effect?
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

just simply print a single char of a string until the end of the string...
put delay every time you print...
Code:#include <stdio.h> #include <string.h> #include <windows.h> int main() { char *eekkss = "wowowowowow"; int len = strlen(eekkss); for (int i = 0; i <= len; i++){ printf("%c", eekkss[i]); Sleep(800); } }
Also read about fflush() as well.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I should of probable mentioned I am programming C on linux.
That is what I did, but I have a problem. It waits the whole 8000 microseconds then prints the whole string to the console. Instead of print 1 char usleep 8000, print another char usleep 8000. I will keep messing with it. Maby someone on here knows what is wrong with it.Code:#include <stdio.h> #include <string.h> #include <unistd.h> int main() { int i; char *eekkss = "This is a test string."; int len = strlen(eekkss); for (i = 0; i <= len; i++){ printf("%c", eekkss[i]); usleep(8000); } }
Are you sure you could fill 8 ms interval?
You could add fflush(stdout) to enforce printf output the char
also note that eekkss[len] is nul-char that should not be printed
char *eekkss - should be
const char*

Thanks. I got it to work ok for now.
I will use usleep for now. Might use something else later in place of usleep.Code:#include <stdio.h> #include <string.h> #include <unistd.h> int main() { int i; const char *eekkss = "This is a test string."; int len = strlen(eekkss); for (i = 0; i <= len; i++){ printf("%c", eekkss[i]); fflush(stdout); usleep(15000); } }
