Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Running time of a program depends on
A
the way the registers and addressing modes are used
B
the order in which computations are performed
C
the usage of machine idioms
D
all of these
Explanation: 

Detailed explanation-1: -In computer science, runtime, run time, or execution time is the final phase of a computer program’s life cycle, in which the code is being executed on the computer’s central processing unit (CPU) as machine code. In other words, “runtime” is the running phase of a program.

Detailed explanation-2: -You use the complexity of an algorithm instead of absolute running times to reason about algorithms, because the absolute running time of a program does not only depend on the algorithm used and the size of the input.

Detailed explanation-3: -Run time is part of the program life cycle, and it describes the time between when the program begins running within the memory until it is terminated or closed by the user or the operating system. Run time is also known as execution time.
