1 表达式和标准输入输出实验
1.1 必做题
1.1.1 程序改错：
（a）题目 下面给出了一个简单 C 语言程序例程，用来完成以下工作：
1) 输入华氏温度 f，将它转换成摄氏温度 c 后输出； 2) 输入圆的半径值 r，计算并输出圆的面积 s； 3) 输入短整数 k、p，将 k 的高字节作为结果的低字节，p 的高字节作 为结果的高字节，拼成一个新的整数，然后输出； 在这个例子程序中存在若干语法和逻辑错误。要求在计算机上对这个例子程 序进行调试修改，使之能够正确完成指定任务。 #include<stdio.h> #define PI 3.14159; voidmain( void ) { int f ; short p, k ; double c , r , s ; /* for task 1 */ printf(“Input Fahrenheit:” ) ; scanf(“%d”, f ) ; c = 5/9*(f-32) ; printf( “ \n %d (F) = %.2f (C)\n\n ”, f, c ) ; /* for task 2 */ printf("input the radius r:"); scanf("%f", &r); s = PI * r * r;
