In UNIX, a pipe is created by using: pipe(fd[]);
Where fd[] is defined as:
int fd[2];
Such that fd[0] is a read end of the pipe and fd[1] is the write end.
Now consider a parent process using the following system call to write to a pipe:
write(fd[WRITE_END], write_message, strlen(write_msg)+1);
If the message to be written is "Hello Class!", which parameter in the write() system call has a value equal to "Hello Class!"?
write_message
WRITE_END
none, another variable or a printf() is needed.
depends on which variable is given that value.

There are two types of primary elections. In a Presidential primary election, voters registered with a political party select the candidate who will represent that party on the ballot in the next general election in November. In its statewide primary, California now has a Top Two Open Primary system, which means that all candidates running for state constitutional, U.S. Congressional, and state legislative offices will be listed on a single statewide primary election ballot. Voters can vote for the candidate of their choice for these offices, regardless of how they are registered. The top two candidates, as determined by the voters, will advance to the general election in November.

In a Presidential primary election, if you are registered to vote with a political party, you will be given a ballot for that party. Each political party has the option of allowing decline-to-state voters to vote in their Presidential primary. Find out how to vote for President based on your party affiliation.
