看不懂啥意思，哪位高手翻译并给出答案一下，多谢：
5) Random numbers can be generated using formula:
Number=shiftingValue+rand()%scalingFactor;
Where shiftingValue is equal to the first number in the desired range of consecutive integers and scalingFactor is equal to the width of the desire range of consecutive integers.Write a formula for generating numbers between 7 and 11(both 7and 11 included).
5) Random numbers can be generated using formula:
Number=shiftingValue+rand()%scalingFactor;
Where shiftingValue is equal to the first number in the desired range of consecutive integers and scalingFactor is equal to the width of the desire range of consecutive integers.Write a formula for generating numbers between 7 and 11(both 7and 11 included).
函数实现如下：
#include<iostream.h>
#include <time.h>
#include <stdlib.h>
void main()
{
srand((unsigned)time(NULL));
int i;
i=rand()%5+7;
cout<<i<<endl;
}
产生一个有范围的随机数
他最后叫你产生一个公式
能随机生成7~11的数字（包括7 和 11）
scalingFactor=11-7+1
shiftingValue=7
所以
Number=7+rand()%5
