I have to modify the code below so that it counts the number of times the user presses Ctrl-C. The new program will print th emessage OUCH!, then OUCH!!, where the number of exclamation points equals the number of times the handler has been called.
In addition, to printing an increasing number of exclamation points, the program should accept an integer as a command line argument. After the user presses Ctrl-C that many times, the program should exit.
In addition the line sleep(1); has the following error message: implicit declaration of function 'int sleep(...)'
Please advise.
Thanks.
- #include <stdio.h>
-
#include <signal.h>
-
-
main()
-
{
-
void f(int);
-
int i;
-
signal( SIGINT, f );
-
for(i=0; i<5; i++ ){
-
printf("hello\n");
-
sleep(1);
-
}
-
}
-
void f(int signum)
-
{
-
printf("OUCH!\n");
-
}
