How Can I Declare and Initialize Multiple Variables in One Line in C ?

Declaring and Defining Multiple Variables in a Single Line in C

When working with multiple variables that require the same initialization value, it can be tedious to declare and define each one individually. C offers a concise solution for this scenario by allowing you to declare and define multiple variables in a single line.

Consider the following example:

int column, row, index = 0;

In this code, the variable index is initialized to zero, while column and row are left uninitialized. To declare and define all three variables to zero in a single line, we can use the following syntax:

int column = 0, row = 0, index = 0;

This line declares three integer variables column, row, and index, and initializes them all to the value 0. The comma-separated list of variables allows us to specify the data type, variable names, and initialization values in one concise statement.

Using this technique can simplify code readability and reduce unnecessary line clutter, especially when dealing with a large number of variables that require the same initialization value.
