用C、C、C#、JAVA做的一个相同的小程序(输出三个数种的最大值).docVIP

1 C比较三个数的大小： #include stdio.h int max(int x,int y,int z) { int A; if(xyz) or (xzy); A=x; if(yxz) or (yzx); A=y; if(zxy) or (zyx); A=z; return (A); } void main() { int a,b,c,d; printf(请输入三个整数); scanf(%d%d%d,a,bc); d=max(a,b,c); printf(max=%d\n,d); } 2 C++比较三个数的大小 #include stdio.h int max(int x,int y) { if (x=y) return x; else return y; } void main() { int a,b,c,d,e; cinabd; c=max(a,b); e=max(c,d); cout”The max number is”eendl; return 0; } 3 C#比较三个数的大小 static void Main(string[] args) { int a = 0, b = 0, c = 0, max = 0; try { Console.WriteLine(请输入第一个数字:); a = Convert.ToInt32(Console.ReadLine()); Console.WriteLine(请输入第二个数字:); b = Convert.ToInt32(Console.ReadLine()); Console.WriteLine(请输入第三个数字); c = Convert.ToInt32(Console.ReadLine()); } catch(Exception e) { Console.WriteLine(输入的不是数字！); return; } if (a b) max = a; else max = b; if (max c) { max = c; } Console.WriteLine(最大数字是: + max.ToString()); } 4 JAVA比较三个数大小 public class test { public static void main(String[] args) { int a = 0; int b = 0; int c = 0; int s = 0; try { BufferedReader in = new BufferedReader(new InputStreamReader( System.in)); System.out.println(please input 1st number:); a = Integer.parseInt(in.readLine()); System.out.println(please input 2nd number:); b = Integer.parseInt(in.readLine()); System.out.println(please input 3rd number:); c = Integer.parseInt(in.readLine()); } catch (Exception e) { System.out.print(pls input number!); } if (a b) s = a; else s = b; if (s c) System.out.print(s); else System.out.print(c); } } 2
