1.Write a program to read a double-type value x that represents angle in radians and a character-type variable T that represents the type of trigonometric function and display the value of
(a) sin(x), if s or S is assigned to T,
(b) cos (x), if c or C is assigned to T, and
(c) tan (x), if t or T is assigned to T
using (i) if……else statement, and
(ii) switch statement.
2. Can we change the value of the control variable in for statements? If yes, explain its consequences. 3. What is a null statement? Explain a typical use of it.
4. Use of goto should be avoided. Explain a typical example where we fi nd the application of
