Print formatting using \t and \n escape sequences

Solved Problem #CPP#2303

Problem Statement - Print formatting using \t and \n escape sequences

Write the following text using the cout chain using \t and \n escape sequences.

Subjects        Marks
---------------------
Computers       100
Physics         95
Mathematics     98

Solution

Run Output

Subjects        Marks

---------------------

Computers    100

Physics           95

Mathematics  98

cout<<“Subjects\tMarks\n”
Using t we format for putting the second column after a tab. The rule is the tab counts characters from the first character of the previous word if it is less than 8 characters wide else fresh space of adjusted 8 characters is generated.. The tab is assumed to be 8 spaces for display unless changed by the output system. For Subjects it is 8 character wide so a new tab space of 8 character will be generated.
<<“———————\n”
Here we need to give dashes according to matter. 8 for subjects 8 for tab space and 5 for Marks. So total 21 dashes should suffice.

<<“Computers\t100\n”
For computers it is 9 characters wide so a space of 7 characters is generated.

<<“Physics\t\t95\n”
For physics it is 7 characters wide to first tab will only generated 1 space and an additional tab is required to generate 8 more space.

<<“Mathematics\t99\n”;
For mathematics it is 11 character wide so the tab will generate just 5 spaces.

For all independent literals we use n at the end for a line break. All the literals can be chained in the same cout chain, or we can write them as different cout instructions as well.

Notes

This kind of tabular printing is done for simple tables only. Proper formatting can be achieved using functions in the iomanip library in c++.

Common Errors

Correct count of letters in the word is important to fix the tab count.
