what is the difference between print and printf?
428655
The difference between printf and print is the format argument. This is an expression whose value is taken as a string; it specifies how to output each of the other arguments. It is called the format string. The format string is very similar to that in the ISO C library function printf .

There are multiple differences. Two crucial ones are: fgets() can read from any open file, but scanf() only reads standard input. fgets() reads 'a line of text' from a file; scanf() can be used for that but also handles conversions from string to built in numeric types.

printf is a generic printing function that works with 100 different format specifiers and prints the proper result string. putchar , well, puts a character to the screen. That also means that it's probably much faster.

The println("...") method prints the string "..." and moves the cursor to a new line. The print("...") method instead prints just the string "...", but does not move the cursor to a new line. Hence, subsequent printing instructions will print on the same line.

sprintf writes formatted text to an array of char , as opposed to a stream. printf("format", args) is used to print the data onto the standard output which is often a computer monitor. sprintf(char *, "format", args) is like printf. ... The file pointer is the only addition to the syntax of printf.

The fprintf function is used for printing information to the screen. The fprintf function prints an array of characters to the screen: fprintf('Happy Birthday\n'); ... To "place" a number into this string of printed characters we use several formatting options, but they all start with a % sign.

The fprintf() function is used to write set of characters into file. It sends formatted output to a stream. Syntax: int fprintf(FILE *stream, const char *format [, argument, ...])

It returns the character written. putchar(c) is defined as putc(c, stdout). fputc behaves like putc, but is a genuine function rather than a macro; it may therefore be used as an argument. fputc runs more slowly than putc, but takes less space per invocation.

2f in c? They are format specifications to print the value of a floating point number with 1 (%. ... The same specification can also be used to read floating point numbers if you are certain that the number input contains exactly that many decimal places.

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.

The two versions have different print statement syntaxes Essentially, in Python 3, the print statement has been replaced with a print () function. For example, in Python 2 it is print “hello” but in Python 3 it is print (“hello”). ... To learn more differences between Python 2 and 3, check out The Python Wiki.

Usage. The wprintf function is found in C, in which writes the output to the stream under control of format strings. the format string specifies how subsequent arguments are converted for output. wprintf is a wide character version of printf format.

Introduction To C C provides standard functions scanf() and printf(), for performing formatted input and output . These functions accept, as parameters, a format specification string and a list of variables.

echo always exits with a 0 status, and simply prints arguments followed by an end of line character on the standard output, while printf allows for definition of a formatting string and gives a non-zero exit status code upon failure. printf has more control over the output format.

The difference is in how you access them. Arguments are accessible through argv . Standard input is accessible through the stdin file descriptor.
