What is %s in C?
We use printf() function with %d format specifier to display the value of an integer variable.
Similarly %c is used to display character, %f for float variable, %s for string variable, %lf for double and %x for hexadecimal variable.
To generate a newline,we use “\n” in C printf() statement..
What does %LF mean C?

What is scanf in C?
In C programming, scanf() is one of the commonly used function to take input from the user. The scanf() function reads formatted input from the standard input such as keyboards.
What is the difference between %S and %C?
%c is the format specifier for character and %s is the format specifier for string(character array). A string is a collection of characters stored in contiguous memory locations. In other words, it is an array of characters. We can use %c to scan character type input from the users.
What is difference between double and float in C?
While float has 32 bit precision for floating number (8 bits for the exponent, and 23* for the value), i.e. float has 7 decimal digits of precision. As double has more precision as compare to that of flot then it is much obvious that it occupies twice memory as occupies by the float data type.
What is %g in printf?
17. Loading when this answer was accepted… This is the full description of the g / G specifier in the C11 standard: A double argument representing a floating-point number is converted in style f or e (or in style F or E in the case of a G conversion specifier), depending on the value converted and the precision.
What does %- 5d mean in C?
That is what %5d means: print a base-10 number in a field of width 5, with the num- ber right-aligned and front-filled with spaces. To make the number left-aligned, a minus sign is. added to the format specifier. To print a number 5. spaces wide and left-justified (left-aligned) the for-
What is difference between %e and %G?
%f represents the data in normal decimal form, upto six decimal places, although you can control, that upto how many decimal places did you want your output. %g represents the decimal format of the answer, depending upon whose length is smaller, comparing between %e and %f.
What is %d called in C?
In C programming language, %d and %i are format specifiers as where %d specifies the type of variable as decimal and %i specifies the type as integer. In usage terms, there is no difference in printf() function output while printing a number using %d or %i but using scanf the difference occurs.
What is %s and %D in C?
%s tells printf that the corresponding argument is to be treated as a string (in C terms, a 0-terminated sequence of char ); the type of the corresponding argument must be char * . %d tells printf that the corresponding argument is to be treated as an integer value; the type of the corresponding argument must be int .
What means & in C?
“*” Operator is used as pointer to a variable. & operator is used to get the address of the variable. … Example: &a will give address of a.
Does printf go to stdout?
Any call to printf will print to stdout, while calls to fprint while print to the specified stream. In the example you give, the second function call will print to stderr. Since you are printing an empty string, you won’t be doing much of anything on either stream, so you won’t see anything of note happen.
Why 4d is used in C?
Answer to your question. You have already printout the int value, the “4” tells the printf to format the output to a length of 4 characters.
What does %3d mean in C?
%3d can be broken down as follows: % means “Print a variable here” 3 means “use at least 3 spaces to display, padding as needed” d means “The variable will be an integer”
What does %2d do in C?
%2d means: Suppose you are printing n= 18999 with printf(“%2d”,n) then it will reserve the output console with 2 character and if the number of digits of n are larger than the specifier then it will print with no spaces, now suppose you print with %6d then what will happen the number of character it will reserve i.e. 6 …
