To implement the Cohen-Sutherland line clipping algorithm in C/C++, you can follow these steps. This algorithm is commonly used for clipping lines against a rectangular window.

```c
#include <stdio.h>

// Define region codes for the 4 regions
#define INSIDE 0 // 0000
#define LEFT 1 // 0001
#define RIGHT 2 // 0010
#define BOTTOM 4 // 0100
#define TOP 8 // 1000

// Define the minimum and maximum window coordinates
#define X_MIN 50
#define X_MAX 100
#define Y_MIN 50
#define Y_MAX 100

// Function to compute the region code of a point (x, y)
int computeRegionCode(int x, int y) {
int code = INSIDE; // Initialize as inside

if (x < X_MIN) // to the left of clip window
code |= LEFT;
else if (x > X_MAX) // to the right of clip window
