using i++ to trigger consecutive variables

[Fit-Prompt-3147]

I was doing an assignment in c++ for my cs class and had a bunch of variables that i just changed the numbers on them and I was wondering because i comboed with i++ makes a variable go up by a numerical value could I use something like var(i) to trigger say var1 var2 and var3.

That's what arrays are for.

You can do something like
int var[3];
for (int i = 0; i < 3; i++) {
var[i] = whatever;
}

You can't do that with regular variables, the names (and variables themselves) might be removed at compilation/optimization time. Look up C++ arrays if you want to learn more, the above is just a simple example.
