題目:Press any key to change color, do you want to try it. Please hurry up!
1.程序分析:
2.程序源代碼:
#include <conio.h> void main(void) { int color; for (color = 0; color < 8; color++) { textbackground(color);/*設置文本的背景顏色*/ cprintf("This is color %d/r/n", color); cprintf("Press any key to continue/r/n"); getch();/*輸入字符看不見*/ } } 【程序33】
