Question

I am programing for a while but for this i couldn’t find an answer yet .

lets say i want to run on a loop when i change the names of the variables.

lets say i have :

int ran1;
int ran2;
int ran3;

now i want to run a for loop that put numbers to them :

for(int k=0;k<3;k++)
 ran%k=k; // this is wrong ,but i am looking for the correct way .
          //output should be :ran1=0 ran2=1 ran3=2..

i know other ways that takes more lines of code .

Answer 1

Make it an array! Using different names differentiated by a number is a bad practice:

int ran[3];

for (int k = 0; k < 3; k++)
{
    ran[k % 3] = k;
}

Now, instead of using ran1, or ran2, you would use ran[1] or ran[2].
Arrays in C are quite confusing, and they are distinct from pointers.
