分数随机获取rand()函数的使用

    	struct Student sArray[5];
    
    };
    
    //定义一个给老师学生赋值的函数
    void allocateSpace(struct Teacher tArray[], int len){
    	
    	string nameSeed = "ABCDE";
    
    	//给老师赋值

    		tArray[i].tName = "Teacher_";
    		tArray[i].tName += nameSeed[i];

    			//分数的设定

这个不是真的随机
