Question

I want to generate some variables using for command. look at code below:

for (char ch='a'; ch<='z'; ch++)
      int ch=0;

It just an example, after running code above, I want to have int a, int b, int c …

another example:

for (int i=0; i<10; i++)
      int NewiEnd=0;

For example after running code above, we will have int New1End, int New2End etc.

Hope I’m clear enough, How can I do such thing in C++??

No, not possible, not exactly. However, this is possible:

std::map<char,int> vars;    
for (char ch='a'; ch<='z'; ch++)
      vars[ch] = 0;

std::cout << vars['a'] << vars['b'] << vars['c'];

You can also have std::map<std::string, int>.

std::map<std::string,int> vars;
for (int i=0; i<10; i++)
    vars["New" + std::to_string(i) + "End"] = 0;
std::cout << vars["New5End"];
