What is the difference between cout and printf?

Printf is a function which needs parameters and format specifiers (%d for int). Cout is stream oriented output stream object where you do not need any format specifiers. printf returns an integer value (the number of characters actually printed) and cout does not return anything. 3.

Can we use cout instead of printf?

cout is used only by c++ while printf can be used by both c and c++. cout example : cout<<”Message”; while printf example : printf(“%d”,sum); cout doesn't require format specifier while c does require.

Which is faster cout or printf?

For int and char* printing std::cout is faster than printf. ... So again, std::cout should be preferred over printf unless the output is of type double.

Is C++ printf?

C++ printf is a formatting function that is used to print a string to stdout. The basic idea to call printf in C++ is to provide a string of characters that need to be printed as it is in the program. The printf in C++ also contains a format specifier that is replaced by the actual value during execution.

What is the difference between printf and printf in C?

“printf” and “fprintf” are functions in C. ... The difference between printf and fprintf is that printf is used to print a formatted string to a standard output which is most of the time a computer screen and fprintf is used to print a formatted string to a specific file.

What can I use instead of printf?

puts() can be preferred for printing a string because it is generally less expensive (implementation of puts() is generally simpler than printf()), and if the string has formatting characters like '%s', then printf() would give unexpected results.

What is the main difference of printf and scanf functions in C language?

So, the main difference is that one is for reading an input (scanf) while the other is for providing an output from the program (printf).

Should I use scanf or CIN?

With synchronization turned off, the above results indicate that cin is 8-10% faster than scanf(). This is probably because scanf() interprets the format arguments at runtime and makes use of variable number of arguments, whereas cin does this at compile time.

Why is cout faster than printf?

Each has its own overheads. Depending on what you print, either may be faster. printf() has to parse the "format" string and act upon it, which adds a cost. cout has a more complex inheritance hierarchy and passes around objects.

What is printf in Java?

The printf() method of Java PrintStream class is a convenience method which is used to write a String which is formatted to this output Stream. It uses the specified format string and arguments to write the string.

What is printf in Python?

In Python, there is no printf() function but the functionality of the ancient printf is contained in Python. To this purpose, the modulo operator % is overloaded by the string class to perform string formatting. Therefore, it is often called a string modulo (or sometimes even called modulus) operator.

Is cout the same as print?

cout is a object for which << operator is overloaded, which send output to standard output device. The main difference is that printf() is used to send formated string to the standard output, while cout doesn't let you do the same, if you are doing some program serious, you should be using printf().

What is the difference between printf and sprintf )?

The printf function formats and writes output to the standard output stream, stdout . The sprintf function formats and stores a series of characters and values in the array pointed to by buffer.

What are the main differences between fprintf () and Fputc () functions?

fprintf does formatted output. That is, it reads and interprets a format string that you supply and writes to the output stream the results. fputs simply writes the string you supply it to the indicated output stream.

What is the difference between printf () and sprintf ()?

printf is equivalent to writing fprintf(stdout, ...) and writes formatted text to wherever the standard output stream is currently pointing. sprintf writes formatted text to an array of char , as opposed to a stream.
