• Say you want to have the ability to create an arc object by sending it 3 2d points. The 3 points are the beginning of the arc, a point on the arc, and an end point; we might name them A, B, C. Quick geometry lesson: Draw lines AB and BC. The perpendicular Bisectors of these intersect at the center of the arc.

This function can only store character type data and no other data type can be stored through this function. This function will echo the character on the screen while inputting.
• Passing Array to a Function in C Programming In this article, you'll learn to pass an array to a function in C. You'll learn to pass both one-dimensional and multi-dimensional arrays.

One way to get input into a program or to display output from a program is to use standard input and standard output, respectively.All that means is that to read in data, we use cin (or a few other functions) and to write out data, we use cout. When we need to take input from a file (instead of having the user type data at the keyboard) we can use input redirection.

It is a part of the header.The getline function extracts characters from the input stream and appends it to the string object until the delimiting character is encountered.

Name

send - send a message on a socket

Synopsis

Dev C Send Input To Function Form

#include <sys/socket.h>

ssize_t send(int socket, const void *buffer, size_tlength, intflags);

Description

The send() function shall initiate transmission of a message from the specified socket to its peer. The send() function shall send a messageonly when the socket is connected (including when the peer of a connectionless socket has been set via connect()).

The send() function takes the following arguments:

MSG_EOR

Terminates a record (if supported by the protocol).

MSG_OOB

Sends out-of-band data on sockets that support out-of-band communications. The significance and semantics of out-of-band data areprotocol-specific.

The length of the message to be sent is specified by the length argument. If the message is too long to pass through the underlying protocol,send() shall fail and no data shall be transmitted.

Successful completion of a call to send() does not guarantee delivery of the message. A return value of -1 indicates only locally-detected errors.

If space is not available at the sending socket to hold the message to be transmitted, and the socket file descriptor does not have O_NONBLOCK set,send() shall block until space is available. If space is not available at the sending socket to hold the message to be transmitted, and the socket filedescriptor does have O_NONBLOCK set, send() shall fail. The select() and poll() functions can be used to determine when it is possible tosend more data.

The socket in use may require the process to have appropriate privileges to use the send() function.

Return Value

Upon successful completion, send() shall return the number of bytes sent. Otherwise, -1 shall be returned and errno set to indicate the error.

Errors

The send() function shall fail if:

EAGAIN or EWOULDBLOCK

The socket's file descriptor is marked O_NONBLOCK and the requested operation would block.

EBADF

The socket argument is not a valid file descriptor.

ECONNRESET

A connection was forcibly closed by a peer.

EDESTADDRREQ

The socket is not connection-mode and no peer address is set.

EINTR

A signal interrupted send() before any data was transmitted.

EMSGSIZE

The message is too large to be sent all at once, as the socket requires.

ENOTCONN

The socket is not connected or otherwise has not had the peer pre-specified.

ENOTSOCK

The socket argument does not refer to a socket.

EOPNOTSUPP

The socket argument is associated with a socket that does not support one or more of the values set in flags.

EPIPE

The socket is shut down for writing, or the socket is connection-mode and is no longer connected. In the latter case, and if the socket is of typeSOCK_STREAM, the SIGPIPE signal is generated to the calling thread.

The send() function may fail if:

EACCES

The calling process does not have the appropriate privileges.

EIO

An I/O error occurred while reading from or writing to the file system.

ENETDOWN

The local network interface used to reach the destination is down.

ENETUNREACH

No route to the network is present.

ENOBUFS

Insufficient resources were available in the system to perform the operation.

The following sections are informative.

Examples

None.

Application Usage

The send() function is equivalent to sendto() with a null pointer dest_len argument, and to write() if no flags are used.

Rationale

None.

Future Directions

The science of good cooking free download. C++ does not allow to pass an entire array as an argument to a function. However, You can pass a pointer to an array by specifying the array's name without an index.

If you want to pass a single-dimension array as an argument in a function, you would have to declare function formal parameter in one of following three ways and all three declaration methods produce similar results because each tells the compiler that an integer pointer is going to be received.

Way-1

Formal parameters as a pointer as follows −

Way-2

Formal parameters as a sized array as follows −

Way-3

Dev Input Event

Formal parameters as an unsized array as follows −

Now, consider the following function, which will take an array as an argument along with another argument and based on the passed arguments, it will return average of the numbers passed through the array as follows −

Now, let us call the above function as follows −

When the above code is compiled together and executed, it produces the following result −

As you can see, the length of the array doesn't matter as far as the function is concerned because C++ performs no bounds checking for the formal parameters.
