[Solved] Declaring a function in a header file which references structs defined in different header files

by

[ad_1] You will need to include file1.h and file2.h in file3.h instead of file3.c. As func3 uses struct1 and struct2, you can’t declare it without having the declarations of the structs on hand. Don’t be tempted to redeclare the structs in file3.h. [ad_2] solved Declaring a function in a header file which references structs defined … Read more

[Solved] Complex command in exec.Command()

by

[ad_1] You don’t have to use the shell for redirection, you can just let Go do it: package main import ( “os” “os/exec” ) func main() { f, e := os.Create(“requirements.txt”) if e != nil { panic(e) } defer f.Close() c := exec.Command( “docker”, “exec”, “-it”, “demoContainer”, “bash”, “-c”, “pip freeze”, ) c.Stdout = f … Read more

[Solved] buffer overflow Identification in the code

by

[ad_1] 1. while ((buffer[i++] = getchar()) != ‘\n’) You have to be sure that the number of characters being entered is less than 4096. Else you have a buffer overflow. While reading until the end of the line it would be better to use fgets() which is much safer. 2. strcpy(newbuffer,buffer); What if your array … Read more

[Solved] What does this following C code implement [closed]

by

[ad_1] The code is probably intended to create an identity matrix with 1’s on the leading diagonal and 0’s elsewhere. The Fortran equivalent of that code is used as the first example of bad code in the classic Elements of Programming Style by Kernighan and Plauger. Working from memory, the Fortran code was roughly: DO … Read more

[Solved] Traverse Non-Binary Tree [closed]

by

[ad_1] def traverse(tree_of_lists): for item in tree_of_lists: if isinstance(item, list): for x in traverse(item): yield x else: yield item This is the “basic” solution — can run in Python 2.7 and gives you an iterable that you can simply loop on. (In recent Python 3.* versions you’d use yield from item instead of the inner … Read more

[Solved] How to make a graphic using numbers with PHP [closed]

by

[ad_1] try something like this. $set = array( 7, 8 ); echo ‘<pre>’; foreach( $set as $number ){ //assuming number is your INT $array = range( 1, $number ); while( count( $array ) ){ echo “\n”; var_export( $array ); //remove first element array_shift( $array ); //remove last element array_pop($array); } } Outputs: For 7 array … Read more

[Solved] Slot Machine in C (gotoxy)

by

[ad_1] You have infinite loops in all functions. If you enter one function you never return. Consider putting this while in main function. #include <stdio.h> #include <time.h> … int main(){ srand( time(0) ); fnSlotMachine(); while(1) { fnSlot1(); fnSlot2(); fnSlot3(); } } … void fnSlot1(){ Sleep(50); fnGotoXY(5, 9); intSlot1 = rand() % 9; printf(” | %i … Read more

[Solved] Use memory on stack

by

[ad_1] why not the program crash, or print some random garbage? The program will not crash as you are not accessing any illegal memory. The stack memory is a part of your program and as long as you are accessing the memory in a valid range the program will not crash. Yes, you can modify … Read more
