题目：利用条件运算符的嵌套来完成此题：学习成绩>=90分的同学用A表示，60-89分之间的用B表示，60分以下的用C表示。 1.程序分析：(a>b)?a:b这是条件运算符的基本例子。-Title: the use of nested conditional operator to complete this question: academic> = 90 points with A classmate said that 60-89 between the use of B said that the 60 points or less with C said. 1. Program analysis: (a> b)? A: b This is a conditional operator s basic example.

电动车从起跑线出发（车体不得超过起跑线），沿引导线到达B点。在“直道区”铺设的白纸下沿引导线埋有1~3块宽度为15cm、长度不等的薄铁片。电动车检测到薄铁片时需立即发出声光指示信息，并实时存储、显示在“直道区”检测到的薄铁片数目。 （2）电动车到达B点以后进入“弯道区”，沿圆弧引导线到达C点（也可脱离圆弧引导线到达C点）。C点下埋有边长为15cm的正方形薄铁片，要求电动车到达C点检测到薄铁片后在C点处停车5秒，停车期间发出断续的声光信息。 （3）电动车在光源的引导下，通过障碍区进入停车区并到达车库。电动车必须在两个障碍物之间通过且不得与其接触。 （4）电动车完成上述任务后应立即停车，但全程行驶时间不能大于90秒，行驶时间达到90秒时必须立即自动停车。 -err
