The usually used input statement is scanf () function.
Syntax of scanf function is
scanf (“format string”, argument list);
The format string must be a text enclosed in double
quotes. It contains the information for interpreting the entire data for
connecting it into internal representation in memory.
Example: integer (%d) , float (%f) , character (%c) or string (%s).
The argument list contains a list of variables each
preceded by the address list and separated by comma. The number of argument is
not fixed; however corresponding to each argument there should be a format
specifier. Inside the format string the number of argument should tally with the
number of format specifier.
Example: if i is an integer and j is a floating point
number, to input these two numbers we may use
scanf (“%d%f”, &i, &j);
