Explanation / Answer

Q1:
Systems programming
C is a general purpose and one of the most widely used programming language. C is one of the language which is used as assembly level and application level, which means it is usd to make system software like an operating systems and application software which works on top most layer as an application in an OS.

Q2:
Having two or more distinct referencing methods, or names, for the same memory cell.
In simple words when two or more variables are pointing towards a same address is called aliasing.
Int x=30,y;
y=&x;
now y is a alias of x, which means both point to same address and having same value 30.

Q3:
Exception handling.
As exception handling is handling of exceptions, and exception as nothing but unchecked errors which can pop up during code run-time. So exception handling is nothing related to readability.

Q4:
Cost of training programmers.
Training programmers is not related to overall cost of programming language.
