Variable character inside a constant

Having defined this:

int var1 = 1;
int var2 = 2;
int var3 = 3;

I want to make this:

int result = varc * 70; // Where c is a previously defined int that can take 1,2 or 3 value.

Solutions? Thank you.

you write:

int result = varc * 70;

This is what you want to make is not possible in language c.

Note: varc is an identifier

Remember IDENTIFIER in C : Identifiers are names for entities in a C program, such as variables, arrays, functions, structures, unions.

It must be unique for all entities and also an identifier is a string of alphanumeric characters

Ok, you remembered. :)

So, you never used "c" present in "varc" to treat(refer) to other variables/identifies/entities.

I hope I might be solve your doubt in easiest way .Thank you! :)

In C you're out of luck on this since it's not a reflective language. That is you can't get the value of a variable by somehow "stringifying" the name you gave it in the source code.

But what you could do is use an array:

int vars[] = {1, 2, 3};

int result = vars[i] * 70;

where i is 0, 1, or 2.
