#include <iostream>

using namespace std;

int main() 
{
   char a = 'a';
   while (a < 'z')
   a++; 
  cout << a; 
}

In the loop, you need to enclose multiple statements in braces:

int main() 
{
    char a = 'a';
    while (a < 'z'){
        a++; 
        cout << a; 
    }
    cout << '\n'; // let's have a line break at the end
}

Otherwise the cout statement is only ran once the loop finishes.

Sadly though this code is not portable since the C++ standard mandates few requirements as to how the alpha characters are encoded. And their being contiguous and consecutive is not a requirement. The portable solution is based on the obvious if ostensibly puerile

int main()
{
    std::cout << "abcdefghijklmnopqrstuvwxyz\n";
}

; if you want to print all letters from a certain value, then use something on the lines of

int main() {
    const char* s = "abcdefghijklmnopqrstuvwxyz";   
    char a = 'k'; // print from k onwards, for example
    for ( ; *s /*to prevent overrun*/ && *s != a; ++s);     
    std::cout << s; 
}

Only thing executed in while is a++; because there are no brackets surrounding statements that belongs to while. to do multiple statements surround them in brackets. Or like in this case its possible to make them into one statement.

#include <iostream>

int main() 
{
    char a = 'a';
    while (a < 'z')
        std::cout << ++a;
}

Need to put the cout inside the loop:

#include <iostream>

int main() 
{
   char a = 'a';
   while (a < 'z')
   {
      a++; 
      std::cout << a << " "; 
   }
}

Also added a space to distinguish the different letters. And removed the using namespace std; as it's not recommended.
