Question: Incrementing Program

InclinedToFall (48)
First things first, here's the code:

1
2
3
4
5
6
7
8

#include "std_lib_facilities.h"

int main(){
	int a = 1;
	cout<<"a == "<<a<<'\n';
	while (a<26){
		cout<<"a"<<" == "<<++a<<'\n';
	}
}


What I want it to do is assign 'b' to 2, c to '3', and so forth. My problem is that as a beginner I don't understand how to (if there even is a way to) increment characters. As in the alphabet a-z, 1-26. I am teaching myself, so this is a slow and tedious process.

Help is much appreciated.

If I have correctly understood you all what you need is to make some minor changes

#include "std_lib_facilities.h"

int main(){
	int a = 0;
	cout<<"a == "<<a<<'\n';
	while (a<26){
		cout<<"a"<<" == "<< char( a++ + 'a' ) <<'\n';
	}
}


Or you can write even simpler

#include "std_lib_facilities.h"

int main(){
	for ( char c = 'a'; c <= 'z'; c++ ) std::cout << c;
	cout << '\n';
	
}

I dont know if you know what arrays are or what the for loop is but I will explain my code to you and If you have questions just ask them.

So first I make an array of chars to represent the different letters in the alphabet. Then I use the for loop to loop through each letter in my array and get the corresponding number to the letter.

#include<iostream>
using namespace std;

int main(){
    //make an array of all the letters in the alphabet.
	char letters[26]={'a','b','c','d','e','f','g','h','i','j','k','l',
                                 'm','n','o','p','q','r','s','t','u','v','w','x','y','z'};

   //loop through the array of letters and get the corresponding number.
	for(int i = 0; i<26; i++){
           cout << letters[i] << " is equal to " << i + 1 << endl;
	}

}

WOW! Great help! I'm trying to only use the tools I currently understand, but arrays look cool!
