How to create a simple colored window using OpenGL with GLFW and Glad in C++

Answer 1

#include <iostream>
#include <glad/glad.h>
#include <GLFW/glfw3.h>

#define SCR_WIDTH 800
#define SCR_HEIGHT 600

int main() {
    // glfw: initialize
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 6);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    // glfw: create window
    GLFWwindow* window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "Window Title", NULL, NULL);
    if (window == NULL) {
        std::cout << "Failed to create GLFW window" << "\n";
        glfwTerminate();
        return -1;
    }
    glfwMakeContextCurrent(window);

    gladLoadGL();

    glViewport(0, 0, 800, 800);

    glClearColor(0.3f, 0.4f, 0.5f, 1.0f);
    glClear(GL_COLOR_BUFFER_BIT);
    glfwSwapBuffers(window);

    while (!glfwWindowShouldClose(window)) {

        glfwPollEvents();
    }

    glfwDestroyWindow(window);
    glfwTerminate();
}
