这段代码的目的是用来返指针*ptr指向值的平方,但是,由于*ptr指向一个volatile型参数,编译器将产生类似下面的代码: int square(volatile int *ptr) { int a,b; a = *ptr; b = *ptr; return a * b; } 由于*ptr的值可能被意想不到地该变,因此a和b可能是不同的。结果,这段代码可能返不是你所期望...
x = 5 Evaluating SQUARE(x): The result is 25. Evaluating SQUARE(2): The result is 4. Evaluating SQUARE(x+2): The result is 17. Evaluating 100/SQUARE(2): The result is 100. x is 5. Evaluating SQUARE(++x): The result is 42. After incrementing, x is 7. 前两行与预期相符,但是...
The counter of the outer for loop keeps track of the current row of the square printing while the counter of the inner for loop keeps track of the position of the graphic being drawn in the current row. Negative arguments for length should be made positive by negation. The function should...
Also, if i change the number of the grid cells either horizontally or vertically or both it should remain square under same conditions as described above. Its the boxes inside the frame which needs to change aspect ratio when the number of boxes in either direction changes. I have tried usin...
(I also tried to add an asterisk after DeclareMathOperator.) This almost works. The problem is that now \sech^2 u places the square above sech, instead of after it (proof). Is there a way to fix this? What is the prefered way to define new functions ('operators') in MathJax?
