方法中的比较因要比较的值的数据类型而异。String.Compare用于此示例,因为为比较选择的属性是字符串。 IComparer 其作用IComparer是提供更多比较机制。 例如,你可能希望在多个字段或属性上提供类的排序、在同一字段上升序和降序,或同时提供这两者的顺序。
Further, we employ the scanf() function. It is used to read the configured data. It stores the entered number. In addition, we apply the if-else condition to check whether the entered number is even or not. We utilize the (%) modulus operator to evaluate if the entered number is perfe...
一、直接使用if-else语句 int num; scanf(“%d”,&num) if(num==1) { printf(“you input is 1\n”); } else printf(“you input is another\n”); 上面的代码表示,如果num=1,输出you input is 1。如果不是,输出you input is another。
