3、重點(diǎn)。在程序中，必須用到一些繪圖函數(shù)。三系統(tǒng)分析和數(shù)據(jù)：此程序主要是實(shí)現(xiàn)簡諧振動的合成，其中，開始利用主函數(shù)調(diào)用一個函數(shù)，對操作進(jìn)行選擇；然后繪出三坐標(biāo)軸，使圖形出現(xiàn)的方位確定;接著，輸入兩分振動的參數(shù)；最后合成三圖形。四程序的說明：此程序是為了實(shí)現(xiàn)簡諧振動的合成。在程序中，開始利用主函數(shù)調(diào)用welcomegui()；函數(shù)，對要進(jìn)行的操作進(jìn)行選擇。然后對圖形坐標(biāo)及圖形顯示在屏幕上的位置進(jìn)行定位，其中運(yùn)用了sprintf()；和outtextxy()；函數(shù)，接著輸入Y1和Y2的參數(shù)，并再次調(diào)用函數(shù)，對操作進(jìn)行選擇，最后，合成處理函數(shù)，同步顯示來年各個分振動和一個合振動。五主要函數(shù)的說明：spri
