Answer: The difference between the scope and linkage is as follows:-
- Scope of the variable is defined as the variable view from different program parts whereas the linkage is described as the link that is made between the variable and the declaration function having the common name.
- Scope of variable describes about the existing time of the variable in the program whereas linkage is defined for the name of variable present in the program is available at all time .
A programming language is not used to talk from human to human. It is used to talk from a human to a computer. Computers are very dumb compared to us, so they need to be taught or spoken to in simple terms. Asking them something complex is far beyond their understanding, as they cannot learn anything beyond what has already been taught to them. Using print: “Hello, World” is the way to tell them to do stuff way less complex than when we say ‘write the words Hello, World on the screen’. A programming language is also not very easy to create. Talking to a computer in a dumb way reduces the process to make a new language for the computer to understand.
