I guess you mean predefined functions or library functions. Well, you don't have to use them, but they can be useful.
I don't use that function in C programme.
To derive the Marshallian demand function from a utility function, you can use the concept of marginal utility and the budget constraint. By maximizing utility subject to the budget constraint, you can find the quantities of goods that a consumer will demand at different prices. This process involves taking partial derivatives and solving for the demand functions for each good.
Yes

This function is obsolete. Do not use it.
To determine demand from a utility function, one can use the concept of marginal utility. By calculating the change in utility for each additional unit of a good consumed, one can determine the level of demand for that good. The point at which the marginal utility equals the price of the good represents the optimal level of consumption and therefore the demand for that good.
Yes, I did.
The importances of law of diminishing marginal utility are given below: a) use in consumption b) use in production c) use in exchange d) use in distribution e) use in public finance.
Because if you donot use main function in c program, the compiler willnot execute the program.C compiler starts execution from main function itself.
TLINK is the Turbo C++ linker utility. You use it to link the object files created by the Turbo C++ compiler.
