How many arguments can printf take?
Printf can take as many arguments as you want. In the man page you can see a at the end, which stands for a var args. If you got 96 times %s in your first argument, you’ll have 97 arguments (The first string + the 96 replaced strings 😉 )
How many arguments can be passed to scanf?
Anyway, the number of conversions is dependent on the format string, not the other arguments. If you pass more arguments than required, the extra ones will just be ignored. In this case, scanf() has always exactly two arguments.
How can printf () and scanf () take multiple arguments?
Each argument takes a size of integer in stack. For data types whose sizes are greater than integer, double or multiples of integer size are taken. Inside the function, we take the pointer of the first argument. We can get the next argument by incrementing the pointer value.
What are the arguments in printf in C?
The argument is interpreted as a long int or unsigned long int for integer specifiers (i, d, o, u, x and X), and as a wide character or wide character string for specifiers c and s. The argument is interpreted as a long double (only applies to floating point specifiers: e, E, f, g and G).
What can I use instead of printf in C?
puts() The function puts() is used to print the string on the output stream with the additional new line character ‘\n’. It moves the cursor to the next line. Implementation of puts() is easier than printf().
Does printf have a limit?
printf() has an upper limit. It will successfully handle up to N char s. N is at least 4095. With such a large (320 kB) expected output, if possible, consider using fputs(s, stream) rather than fprintf(stream, “%s”, s); which does not have this 4095 limitation.
IS puts faster than printf?
In my experience, printf() hauls in more code than puts() regardless of the format string. If I don’t need the formatting, I don’t use printf . However, fwrite to stdout works a lot faster than puts .
Which is better cout or printf?
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().
How do you take 3 integers in a single line in Python?
In C++/C user can take multiple inputs in one line using scanf but in Python user can take multiple values or inputs in one line by two methods. Using split() method : This function helps in getting multiple inputs from users. It breaks the given input by the specified separator.
How do I set precision in printf?
A printf precision specification always begins with a period (.) to separate it from any preceding width specifier. Then, like width, precision is specified in one of two ways: Directly, through a decimal digit string. Indirectly, through an asterisk (*).
