Question:what are the constants?Explain in brief?
AnswerWhen we declare any variable as constant than we can't be modify the value of that variable at run time.Constants can come in any data type that the C compiler supports. A special constant, the string, can be used to either initialize a character array or be substituted for one.
Some constant in C:
123: int,In the smallest size and type that will hold the value specified.
123U: unsigned int,in the smallest size and type that will hold the value specified.
123L: long int,signed
123UL: long int,unsigned
'A': Character constant
"ABCD": Character string constant
7.89:double-floating-print constant
7.89F:float-floating-print constant
7.89F:long double-floating-point constant
