c - Printing contents of matrix by using pointer -

-

यहाँ मेरा काम है: arrPrintMatrix (int * matrix, int m, int n): सामग्री की छापें मैट्रिक्स [मी] [एन] तालिका प्रारूप में।

और यहां मेरा कोड है: 

  #include & lt; stdio.h & gt; # शामिल करें & lt; malloc.h & gt; Int main () {शून्य arrPrintMatrix (int * मैट्रिक्स, int m, int n); इंट मैट्रिक्स [2] [3] = {{5, 10, 15}, {0, 2, 4}}; Int * ptr; Ptr = & amp; मैट्रिक्स [0] [0]; अर्रप्रिंटमैट्रिक्स (पीटीआर, 2, 3); वापसी 0; } शून्य arrPrintMatrix (int * matrix, int m, int n) {int i, j; के लिए (i = 0; i & lt; m; i ++) {printf ("\ n"); के लिए (जे = 0; जम्मू & lt; n; j ++) {printf ("% d \ t", मैट्रिक्स [i] + j); }}}

लेकिन जब मैं यह कोड चलाता हूं, मुझे पहली पंक्ति के रूप में 5 6 और 7 मिलता है, 10 11 और 12 दूसरी पंक्ति के रूप में। तो मैट्रिक्स [i] + j के साथ कुछ गलत है मुझे यह कैसे ठीक करना चाहिए?

वैसे भी, मैं संकेतकों, मॉलोक, फ़ंक्शन के संकेत के सरणियों के बारे में इतनी उलझन में हूँ, आम तौर पर मैं संकेतकों के बारे में उलझन में हूं मुझे खुशी होगी अगर आप उस बारे में कुछ वेब पेज या वीडियो का सुझाव देते हैं।

रेखा को बदलें 

  printf ("% d \ t", मैट्रिक्स [i] + j);

से 

  printf ("% d \ t", मैट्रिक्स [i * n + j]);

अपडेट

2 डी सरणियों की स्मृति का लेआउट अच्छी तरह से समझाया गया है।

uislider - In a MATLAB GUI, how does one implement a continuously varying slider from a GUIDE created .m file? -

I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...

I would like to create a fuel bar (empty with full tank). When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
