PROGRAMING IN C BY BALAGURUSWAMY PDF

Transmission is in half-duplex mode. For PSK the baud rate is the same as the bandwidth, which means the baud rate is But in 8-PSK the bit rate is 3 times the baud rate, so the bit rate is 15, bps. In the analog transmission of digital data, the signal or baud rate is less than An analog signal has a bit rate of bps and a baud rate of baud.

We cannot extend the range of character. We can extend the range of float by using double. To extend the precision further we may use long double. Question: What is an unsigned integer constant? What is the significant of declaring a constant unsigned? We can take the value double using an unsigned integer constant. Question: Describe the characteristics and purpose of escape sequence characters.

Answer: C supports some special back slash character constants, that are used in output function. This characters are known as escape sequence characters. Answer: A variable is a data name that may used to store a data value.

Like constants that remains unchanged during the execution a program. The meant of value it is a variable name and it can take any value like character, int, float and double. Question: How do variables and symbolic names differ? Answer: A variable may be used to store data value.

A variable may take different values at different times during execution of a program. Variables has need to declare at the beginning of the body but after the main. Symbolic names is a unique constants. This constants may appear in a number of place in the program. Symbolic names has need to define at the beginning of a program. Question: State the difference between the declaration of a variable and the definition of a symbolic name? Answer: Variables has need to declare at the beginning of the body but after the main.

The syntax for declaring a variable is as follow: Data-type v1,v2,…….. For example, valid declarations are int count; int number,total; float ratio; Symbolic names has need to define at the beginning of a program. Why it is important? Answer: The process of giving initial values to variables is called initialization.
