A tarefa é imprimir os alfabetos de A a Z usando um loop .

No programa abaixo, o loop for é usado para imprimir os alfabetos de A a Z. Uma variável de loop é usada para fazer isso do tipo 'char'. A variável de loop 'i' é inicializada com o primeiro alfabeto 'A' e incrementada em 1 em cada iteração. No loop, este caractere 'i' é impresso como o alfabeto.

Programa: 

// C++ program to find the print
// Alphabets from A to Z
#include <bits/stdc++.h>
using namespace std;
 
int main()
{
    // Declare the variables
    char i;
 
    // Display the alphabets
    cout << "The Alphabets from A to Z are: \n";
 
    // Traverse each character
    // with the help of for loop
    for (i = 'A'; i <= 'Z'; i++)
    {
 
        // Print the alphabet
        cout << i <<" ";
    }
 
    return 0;
}
