Afunction pointeris a pointer variable that can store address of a function and then using the function pointer we can call initialized function in our program. Steps to Use Function Pointer in C 1. Declaration offunction pointer return_type (*fun_pointer_name)(argument_type_list); 2. Initia...
There is some other function that behaves almost like the rewind() function in C with very minute differences. That behavior can be used in accordance with the requirement of functions like fseek() function fsetpos() function. There is no time complexity which means for rewind() function, the...

initgraph(&gd,&gm,"C:\\TC\\BGI"); color = getpixel(0, 0); sprintf(array,"color of pixel at (0,0) = %d", color); outtext(array); getch(); closegraph(); return 0;} Since we haven't drawn anything on the screen, and the default screen color is BLACK, the color of the ...
getch(); } 答案: Thank you for the replies. So the first problem was in my source file i had a .cpp file rather than a .c file. Then I found that I wasn't exactly pointing to the entry point of my program properly. So this is now fixed. Thank you to all that replied....
randomize(); 不是标准函数,不是每个C系统都会有,而在有它的系统中,它通常是一个宏,定义可以是这样的:define randomize() srand((unsigned)time(NULL))应该用srand(time(NULL));替换你程序中的randomize();并且,它应该放在循环之前,只执行一次(不应该放在循环内部),否则每次得到的随机数都相同.
getch() ; return 0; } Output: Dervl's display called Derv2's display called Explanation: This program’s output reveals that the member function display() of the derived classes are invoked and not that of the base class as expected. By defining the member function display () as virtual...
This is two bytes of a, and two bytes in memory next to a that could belong to another variable, this is stack corruption.If you do manage to force the compiler to do it, this will actually end up with a runtime error:So the only way to get this to work without an error is...
Re: where do I find the definition of the getch function return codes I am going to mark this thread as answered since you have not followed up with any further information on your problem as requested - I assume you solved the problem yourself or one of the suggestions in this thread ...
