在C语言中，无法直接在控制台输出图片。因为控制台只支持文本输出，无法显示图像。如果想在C语言中显示图片，可以使用图形库如OpenGL或者SDL等。这些库提供了图形绘制的功能，可以在窗口中显示图片。以下是一个使用SDL库在窗口中显示图片的示例：
#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，需要将要显示的图片命名为"image.bmp"，并与C源文件放置在同一目录下。然后使用SDL库加载图片并创建窗口、渲染器以及纹理，最后在窗口中绘制纹理。程序会一直运行，直到窗口被关闭。
