In C language, int is a basic variable type used to store integer values. Its complete definition is "integer", its length is usually 32 bits (4 bytes), and the value range is -2147483648 to 2147483647.

To use the int type, you can declare a variable using the following syntax:

int myVariable;  // 声明一个名为myVariable的整数变量

The variable is not initialized at this time, so its value defaults to 0. To assign a value to a variable, you can use a simple assignment statement:

myVariable = 42; // 将变量myVariable赋值为42

You can also initialize the variable while declaring it:

int myVariable = 42; // 声明并初始化myVariable为42

Here is a sample code showing how to declare and use an int Variable of type:

#include <stdio.h>
int main() {
  int age = 25;
  printf("I am %d years old.\n", age);
  return 0;
}

This code declares an integer variable named age and initializes it to 25. Then use the printf function to print out the value of the variable.

The output result is:

I am 25 years old.
