// Import necessary libraries #include <GL/glew.h> #include <GLFW/glfw3.h>

// Define a simple fragment shader const char* fragmentShaderSource = R"glsl( #version 330 core out vec4 FragColor; void main() { FragColor = vec4(1.0f, 0.5f, 0.2f, 1.0f); } )glsl";

return 0; } This example demonstrates how to create a simple OpenGL 4 program, including setting up the window, creating and compiling shaders, and drawing a triangle.

// Clean up glDeleteProgram(program); glDeleteShader(fragmentShader); glDeleteShader(vertexShader); glfwTerminate();

// Use the program and draw a triangle while (!glfwWindowShouldClose(window)) { glClearColor(0.2f, 0.3f, 0.3f, 1.0f); glClear(GL_COLOR_BUFFER_BIT);
