What do we mean by the charge on a body is denoted by "q"?

In summary, the conversation discusses the concept of electric charge and how it is a characteristic property of subatomic particles and can be transferred to a body by the transfer of electrons. The charge on a body is denoted by q, which is the numeric value of the charge measured. This value can be positive or negative, with the fundamental unit of charge being |e|, the electronic charge. The line "the charge on a body" refers to the amount of excess charge on a body, which can be measured and denoted by q.

sophiecentaur, you tell me am I correct here ?

Ok, so this line--> "The charge on a body is denoted by q" means here we are talking about the amount of charge on a body.
So, q denotes the amount of charge on a body which is of the form --> q= ne

and we can choose to express that value as a number and a unit of measure.

Suppose If we are given this equation q=+2C , so this means that a body has the property of electric charge and the amount of electric charge this body has is +2C, Which is represented by q.

This means that suppose a body has the property of electric charge and we measure it and it was found out to be +2C. So, we denote this +2C by q. Thus, this equation q=+2C is the mathematical representation of the above statement.
You have written the above at least four times, but still don't seem to be getting it, and you're really overthinking things. What you have written is very verbose -- much of what you have written can be omitted with no loss of meaning.
A clearer way to say this would be "A body has a charge q of 2 C (2 Coulombs)."

Although the charge q is a function of the number of excess or absent electrons, we don't normally write the charge as some constant n times e, the charge on an electron. Instead we measure the charge in Coulombs.
The letter q is used to represent the charge.

Instead, we write this in terms of Coulombs.

And after measuring this propety ,We denote this amount of charge(numeric value) by q.

so, we write q= +2C
I have quoted some of your repeated statements from posts #7, #21, #21, and I believe, #30.
You keep asking the same question, which has been amply answered. Instead of repeatedly asking the same question over and over, spend some time reviewing your textbook's presentation on charge.
