If you observe closely, you may see that these stars are shown only against some slides and not all of them.

The stars are just an indication that the particular slide has custom animation. That was you can quickly see at a glance if a slide has content that is animated.

The same star symbol is also shown when the slide itself has any slide transition set.

Write a program "addnumbers.c" where it takes as many arguments as the user includes as command line arguments and calculates th
gogolik [260]

Answer:

#include <stdio.h>

#include <stdlib.h>

int main(int argc, char* argv[])

{

int first, second, total;

if (argc < 2)//checking if there are enough arguments

{

 printf("not enough values\n");

 return -1;//terminate program

}

total = 0;

for (int i = 1; i < argc; i++)

{

 //atoi convert a string into int. doing this to use operator

 total = total + atoi(argv[i]);//add current total to next argumment

}

printf("final total sum: %d\n", total);//printing final total

return 0;

}

Explanation:

For command line arguments you have to use command prompt. It varies depending on you machine and where you code is placed.

So, go to command line, called "command prompt" on Windows. This should open the black screen, also called the Terminal. A picture is attached in the answer. Then you have to NAVIGATE to the directory of your program. So, let's say your code is on your desktop. You will have to navigate to your desktop. To do this, type:

"cd Desktop", and press enter.

The picture of my process is attached below too.

Then, the program we have made is called addnumbers. we will type,

"addnumbers 10 20 30 40 50"

add numbers is the name of the program followed by arguments, separated with spaces.

MrRissso [65]

Answer:

Complete code is given below:

Explanation:

#include <stdio.h>

#include <sys/types.h>

#include <unistd.h>

#include <time.h>

#include <sys/wait.h>

int main(int argc , char *argv[]){

pid_t mypid, childpid;

int status;

int i,n;

time_t t;

     

mypid = getpid();

printf("pid is %d.\n", mypid);

childpid = fork();

if ( childpid == -1 ) {

perror("Cannot proceed. fork() error");

return 1;

}

 

 

if (childpid == 0) {

 

 

mypid = getpid();

 

 

childpid = fork();

if ( childpid == -1 ) {

perror("Cannot proceed. fork() error");

return 1;

}

 

if (childpid == 0) {

 

mypid = getpid();

printf("Child pid is %d.\n", getppid());

 

childpid = fork();

 

 

if ( childpid == -1 ) {

perror("Cannot proceed. fork() error");

return 1;

}

random((unsigned) time(&t));

printf(" parent id = %d : Random = %d\n",mypid , (int)(random()% 100 +1));

printf("child id = %d : Random = %d\n",getpid , (int)(random()% 100 +1));

 

if (childpid == 0) {

 

printf("Child 2: I hinerited my parent's PID as %d.\n", mypid);

 

mypid = getpid();

printf("Child 2: getppid() tells my parent is %d. My own pid instead is %d.\n", getppid(), mypid);

 

sleep(30);

return 12;

} else return 15;

} else {

 

while ( waitpid(childpid, &status,0) == 0 ) sleep(1);

 

if ( WIFEXITED(status) ) printf("Child 1 exited with exit status %d.\n", WEXITSTATUS(status));

else printf("Child 1: child has not terminated correctly.\n");

}

} else {

printf(" fork() is ok and child pid is %d\n", childpid);

wait(&status);

 

if ( WIFEXITED(status) ) printf(" child has exited with status %d.\n", WEXITSTATUS(status));

else printf(" child has not terminated normally.\n");

}

 

return 0;

}

Output:

pid is 24503.

Child   pid  is 24565.

parent id = 24566 : Random = 87

child id = 1849900480 : Random = 78

pid is 24503.

Child 1  exited with exit status 15.

pid is 24503.

fork() is ok and child pid is  24565

child has exited with status 0.
