在C語言中，無法直接在控制臺輸出圖片。因為控制臺只支持文本輸出，無法顯示圖像。如果想在C語言中顯示圖片，可以使用圖形庫如OpenGL或者SDL等。這些庫提供了圖形繪制的功能，可以在窗口中顯示圖片。以下是一個使用SDL庫在窗口中顯示圖片的示例：

#include <stdio.h>
#include <SDL.h>

int main(int argc, char *argv[]) {
    SDL_Window *window = NULL;
    SDL_Renderer *renderer = NULL;
    SDL_Texture *texture = NULL;
    SDL_Surface *imageSurface = NULL;

    // Initialize SDL
    if (SDL_Init(SDL_INIT_VIDEO) < 0) {
        printf("SDL could not initialize! SDL_Error: %s\n", SDL_GetError());
    } else {
        // Create window
        window = SDL_CreateWindow("Image Viewer", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 640, 480, SDL_WINDOW_SHOWN);
        if (window == NULL) {
            printf("Window could not be created! SDL_Error: %s\n", SDL_GetError());
        } else {
            // Create renderer
            renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);
            if (renderer == NULL) {
                printf("Renderer could not be created! SDL_Error: %s\n", SDL_GetError());
            } else {
                // Load image
                imageSurface = SDL_LoadBMP("image.bmp");
                if (imageSurface == NULL) {
                    printf("Image could not be loaded! SDL_Error: %s\n", SDL_GetError());
                } else {
                    // Create texture
                    texture = SDL_CreateTextureFromSurface(renderer, imageSurface);
                    if (texture == NULL) {
                        printf("Texture could not be created! SDL_Error: %s\n", SDL_GetError());
                    } else {
                        // Clear renderer
                        SDL_RenderClear(renderer);
                        // Draw texture
                        SDL_RenderCopy(renderer, texture, NULL, NULL);
                        // Update renderer
                        SDL_RenderPresent(renderer);

                        // Wait for window close event
                        SDL_Event event;
                        int quit = 0;
                        while (!quit) {
                            while (SDL_PollEvent(&event) != 0) {
                                if (event.type == SDL_QUIT) {
                                    quit = 1;
                                }
                            }
                        }
                    }
                }
            }
        }
    }

    // Free resources
    SDL_DestroyTexture(texture);
    SDL_FreeSurface(imageSurface);
    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}

在上述示例中，需要將要顯示的圖片命名為"image.bmp"，并與C源文件放置在同一目錄下。然后使用SDL庫加載圖片并創建窗口、渲染器以及紋理，最后在窗口中繪制紋理。程序會一直運行，直到窗口被關閉。
