Can You Initialize Variables of Different Data Types in a C for Loop?

Mixing Variable Types in for Loop Initialization

In C , can one declare variables of different data types within the initialization part of a for loop? For instance:

for (int i = 0, j = 0; ...

Can this syntax be modified to initialize an integer (int) alongside a character (char)? If so, how is this achieved?

Answer:

Directly declaring variables of different types within the initialization part of a for loop is not possible. However, there is a technical workaround, though its practical usage is questionable:

for (struct { int a; char b; } s = { 0, 'a' }; s.a < 5; ++s.a) 
{
    std::cout << s.a << " " << s.b << std::endl;
}

This method uses a struct to create a single entity with both an integer and a character member, allowing for their simultaneous initialization.
