Answer 2

Option a is the correct answer. %s is used as the format specifier which prints a string in C printf or scanf function.

• In C, %s allows us to print by commanding printf() to print any corresponding argument in the form of a string.
• The argument used is "char*" for %s to print.
• %s does the same command for scanf also. There is a slight difference here, scanf() reads the sequence of characters until it is manually stopped by a space.
• Printf() in C programming language is used to print any character, string, integer, octal onto the output screen.
• In the "C "programming language, scanf() is used to take input from the user. It reads the input already present in the user.
