This is the 17th module on learning C with us. Earlier we discussed on the basic introduction and structure of C, preprocessor it's features, intermediate and executable codes. compilation and execution process of a C program. And keywords and identifiers, data types, variables and constants, scope of variables, operators and expressions in C. Type casting in #C. Introduction to input and output functions and reading a character in #C.
In this section we will discuss on the input and output functions. Formatted input and output functions of #C.
For unformatted input functions you may refer to module 16 here ? :
Formatted input functions :-
printf() and scanf() are example of formatted input functions. In formatted input functions we specify the type / format of the data we read/display.
printf() is an example of formatted output function and scanf() is an example of formatted input function.
printf() and scanf() with format specifier :-
Formatted input refers to an input data that has been arranged in a particular format for that we have scanf.
Control string specifies field format in which data is to be entered.
arg1,arg2.......argn specifies address of loactions or variables where data is stored.
Eg. scanf("%d %d %d",&a,&b);
For formatted output we use printf as :
Eg. printf("%d %d",&a,&b);
printf("enter two values");
In next module we will continue our discussions on the most important topic that is control statements. For more information regarding #C please be updated with us only on Www.newsandstory.com as we provide all the information on all the topics covered in #C.
