问题 I wrote a program to calculate a square finite difference matrix, where you can enter the number of rows (equals the number of columns) -> this is stored in the variable matrix. The program works fine: program fin_diff_matrix implicit none integer, dimension(:,:), allocatable :: A integer :: matrix,i,j print *,'Enter elements:' read *, matrix allocate(A(matrix,matrix)) A = 0 A(1,1) = 2 A(1,2) = -1 A(matrix,matrix) = 2 A(matrix,matrix-1) = -1 do j=2,matrix-1 A(j,j-1) = -1 A(j,j) = 2 A(j,j+1) =

Output of a C string program

问题 #include<stdio.h> int main() { char s[2]="a"; s[1]='b';s[2]='c';s[3]='d';s[5]='e'; printf("%s $%c$",s,s[4]); return 0; } 1.When I run this program in C (gcc-4.7.2) I expected Runtime Error because of the missing Null Character ('\0'). 2.If still the program compiles and executes successfully ,since s[4] has not been initialised,I expected some garbage value at that place..but here also I was wrong. The output of the above program is: abcde $$ There is no character between the two $(dollor)

问题 Im making a hangman game, at the start of the game the word that the player must guess is printed as stars. I have just started making it again after attempting to write it once and just having messy code that i couldn't bug fix. So I decided it best to write it again. The only problem is, when i try to get my array to print out by using array.ToString(); it just returns System.char[]. See below. code: class Program { static void Main(string[] args) { string PlayerOneWord; string

Powershell Join-Path showing 2 dirs in result instead of 1 - accidental script/function output

我们两清 提交于 2019-11-27 07:24:38
问题 I am constructing incremental directory structures, and for some reason Join-Path is showing 2 dirs. When I later join that with a file I'm sending to copy-item, it causes an error, as shown below. I have shown in the comment for the $to_loc_finalDT1 line, where I first see these two dirs: Copy-Item : Cannot find path '\\T2\DisasterBackup\Loc_2019-03-08\Privileges\Privileges_HH_Bak.csv \\T2\DisasterBackup\Loc_2019-03-08\Privileges\Privileges_HH_Bak.csv' because it does not exist So this is

How to remove square brackets from list in Python? [duplicate]

可紊 提交于 2019-11-27 06:49:01
This question already has an answer here: Print list without brackets in a single row 10 answers LIST = ['Python','problem','whatever'] print(LIST) When I run this program I get [Python, problem, whatever] Is it possible to remove that square brackets from output? You could convert it to a string instead of printing the list directly: print(", ".join(LIST)) If the elements in the list aren't strings, you can convert them to string using either repr (if you want quotes around strings) or str (if you don't), like so: LIST = [1, "foo", 3.5, { "hello": "bye" }] print( ", ".join( repr(e) for e in

How to pipe stdout while keeping it on screen ? (and not to a output file)

时光总嘲笑我的痴心妄想 提交于 2019-11-27 05:50:35
I would like to pipe standard output of a program while keeping it on screen. With a simple example ( echo use here is just for illustration purpose) : $ echo 'ee' | foo ee <- the output I would like to see I know tee could copy stdout to file but that's not what I want. $ echo 'ee' | tee output.txt | foo I tried $ echo 'ee' | tee /dev/stdout | foo but it does not work since tee output to /dev/stdout is piped to foo Here is a solution that works at on any Unix / Linux implementation, assuming it cares to follow the POSIX standard. It works on some non Unix environments like cygwin too. echo
