what is the difference between standard output and error output?

The standard output stream is typically used for command output, that is, to print the results of a command to the user. The standard error stream is typically used to print any errors that occur when a program is running.

printf() and fprintf() both are used for formatted output(write). The only difference is that printf() write directly into standard console (monitor) where as fprintf() take file stream as a parameter where to write.

In Excel, you can display error bars that use a standard error amount, a percentage of the value (5%), or a standard deviation. Standard Error and Standard Deviation use the following equations to calculate the error amounts that are shown on the chart.

The standard error is a statistical term that measures the accuracy with which a sample distribution represents a population by using standard deviation. In statistics, a sample mean deviates from the actual mean of a population—this deviation is the standard error of the mean.

Put simply, the standard error of the sample mean is an estimate of how far the sample mean is likely to be from the population mean, whereas the standard deviation of the sample is the degree to which individuals within the sample differ from the sample mean.

You need to understand what is input errors the input errors is includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts. Here in your case input errors are exactly same as giants i.e. 459. So these input errors is because of giants.

An error is an indication of an unexpected condition that occurs due to lack of system resources while an exception is an issue in a program that prevents the normal flow of the program. Thus, this is the main difference between Error and Exception in C#.

Python print() Function The print() function prints the specified message to the screen, or other standard output device. The message can be a string, or any other object, the object will be converted into a string before written to the screen.

['dy = y0-y1 ; % error.', 'abs_dy = abs(y0-y1) ; % absolute error.', 'relerr = abs(y0-y1)./y0 ; % relative error.', 'pererr = abs(y0-y1)./y0*100 ; % percentage error.', 'mean_err = mean(abs(y0-y1)) ; % mean absolute error.', 'MSE = mean((y0-y1).^2) ; % Mean square error.']

['int a = 1;', 'int b = 2;', 'System. out. print(a != b); // prints true to standard system output.']

The %s specifier converts the object using str(), and %r converts it using repr(). ... For example, if you have a string with endline characters, %s would actually show stuff on new lines while %r would just give the output as \n and also keep the quotes intact.

There are three kinds of errors: syntax errors, runtime errors, and logic errors. These are errors where the compiler finds something wrong with your program, and you can't even try to execute it. For example, you may have incorrect punctuation, or may be trying to use a variable that hasn't been declared.

Recap. There are two places programs send output to: Standard output ( stdout ) and Standard Error ( stderr ); You can redirect these outputs to a different place (like a file); ... Using 2>&1 will redirect stderr to whatever value is set to stdout (and 1>&2 will do the opposite).

puts() writes the string s and a trailing newline to stdout. The function printf() writes output to stdout, under the control of a format string that specifies how subsequent arguments are converted for output. ... int printf(const char *format, ...);

The difference between 'error' and 'mistake' is in the context that they are used in. A 'mistake' is usually accidental, you know it is wrong. Otherwise, an 'error' is usually made due to the lack of knowledge and is more formal than 'mistake'. "Machines never make mistakes, but rather they make errors.

Generally, use an output parameter for anything that needs to be returned. When you want to return only one item with only an integer data type then it is better to use a return value. Generally, the return value is only to inform success or failure of the Stored Procedure.

Serial. print() prints only the number or string, and Serial. println() prints it with a newline character. On a standard Arduino, this function waits while the data is transmitted.
