编写一个C源程序,输入一个长方形的长和宽,计算周长面积 代码:#include void main(){int x,y;printf(\"请输入长:\\n\");scanf(\"%d\",&x);printf(\"请输入宽:\\n\");scanf(\"%d\",&y);printf(\"周长:%d\\n\",2*(x+y));printf(\"面积:%d\\n\",x*y);}图:
求Csharp编程代码 调用Console.WriteLine(GoldbachConjecture(6,100,5,\"{0}={1}+{2};哥德巴赫猜想public static string GoldbachConjecture(int startNumber,int endNumber,int maxLength,string formatString){StringBuilder result=new StringBuilder();List primeNumbers=GetPrimeNumber(endNumber);排除2的数字primeNumbers.RemoveAt(0);循环区间内的偶数int index=0;for(int i=Math.Max(6,startNumber);i Math.Sqrt(i)){break;}}如果是质数if(isPrimeNumber){primeNumbers.Add(i);}}return primeNumbers;}
编写程序,实现从键盘输入两个整数,输出它们的加减乘除取余五种算术运算结果的功能 includeint main(){int x,y;printf(\"请输入第一个数:\\n\");scanf(\"%d\",&x);printf(\"请输入第二个数:\\n\");scanf(\"%d\",&y);prinf(\"相加:%d\\n\",x+y);prinf(\"相减:%d\\n\",x-y);prinf(\"相乘:%d\\n\",x*y);prinf(\"相除:%.2f\\n\",x/(y*1.0));把y*1.0转换成float类型的printf(\"取余:%d\",x%y);}
入门c语言题:从键盘上输入任意一个整数,然后输出它的绝对值 方法一:/用数学函数#include#includevoid main(){ int a;scanf(\"%d\",&a);printf(\"%d\\n\",abs(a));}方法二:/判断#includevoid main(){ int a;scanf(\"%d\",&a);if(a>;=0)printf(\"%d\\n\".
