c int

To declare an integer variable in the C programming language, you can use the following syntax:

int variableName;

This creates a variable named "variableName" of type "int". You can then assign a value to this variable using the assignment operator "=", like this:

variableName = 10;

Alternatively, you can declare and initialize the variable in a single line, like this:

int variableName = 10;

Remember to replace "variableName" with your desired variable name, and "10" with the initial value you want to assign to the variable.
