Answer:
Header files serve two purposes. System header files declare the interfaces to parts of the operating system. You include them in your program to supply the definitions and declarations you need to invoke system calls and libraries.
Answer:
mkdir -m 770 sales
Explanation:
The command mkdir is used to create a directory and the attribute or flag
-m is used to assign permissions on create a folder.
Example:
mkdir -m 770 sales
Create a folder with permissions 770 with name sales
Answer:
The velocity at 30 centimeters down the ramp will be considerable higher compared to 10 centimeters down the ramp.
Explanation:
It is a non lineair problem, since the speed is increasing while rolling down the ramp.
We will expect therefore, that the graph of speed (on the y-axis) and position (on the x-axis) will NOT be a streight line.
if you could plot some values given, with speed (on the y-axis) and position (on the x-axis), then you could draw a smooth line through them, which would give an estimate of all points in between them.
What can be stated with only so limited information, is that the velocity at 30 centimeters down the ramp will be considerable higher compared to 10 centimeters down the ramp.
Answer:
Execution Time, Memory storage,Readiability,
debugging,Platform independent
Explanation:
High level programming languages are the language which is user friendly languages. There is high level abstraction from internal machine code. Here we need compiler to translate that into machine code
Ex: C,c++,Java...
Interpreted languages are scripting languages where we need interpreter to interpret those scripts or commands
Ex:Python.Ruby
Machine languages are binary language which contains 0's and 1's can understandable by system only. Not human readable forma
Interpreted language scans each statement at a time and interprets that line by line. It takes less amount of time to analyze the source code but the overall execution time is slower.
High level language takes more memory than interpreted and machine as it generates some intermediate code
High level languages are more readable than remaining two
Intermediate languages are easy to debug as it executes line by line and when ever any error occurs in a particular line it stops and intimate there itself
High level and interpreted languages are platform dependent, it can work on some machine and OS specific configurations only
