In C programming, a powerful and versatile language, managing data efficiently is crucial. Among the key components of C are variables, which store data values, and data types, which define the kind of data a variable can hold. One of the fundamental data types in C is int, used to represent integer values, including positive numbers, negative numbers, and zero. Here's how to declare an integer variable and assign it a value:

// Declaration of an integer variable
int a;

// Assignment of a value to the variable
a = 10;

You can also declare and initialize an integer variable in a single line. This is useful for saving code space and improving readability. The following example demonstrates this approach:

int b = 20;

Once you have declared your integer variables, you can perform various operations on them. Arithmetic operations such as addition, subtraction, multiplication, and division can be easily implemented. Here's an example illustrating some of these operations:

int result;
result = a + b;  // Addition
result = a - b;  // Subtraction
result = a * b;  // Multiplication
result = a / b;  // Division

In addition to basic operations, C provides the capability to manipulate integers through increment and decrement operators. The ++ operator increases the value of an integer by 1, while the -- operator decreases it by 1. Here’s how you can use these operators:

a++;  // a is now 11
b--;  // b is now 19

To use an integer variable effectively, it’s crucial to understand how to output its value. The printf function from the standard library can be used for this purpose. Here’s an example of how to display the value of an integer variable:

#include <stdio.h>

int main() {
    int a = 10;
    printf("The value of a is: %d\n", a);
    return 0;
}
