Segmentation fault (core dumped) (C, and C++ programming) This is popular error in programming with arrays. It comes due to overshooting the memory limit by declaring the array in static memory allocation . You can solve this by using the dynamic memory allocation of the arrays. All you have to do is declare your array as follow: For (C programming) For one dimensional array: int *a; a = (int *)malloc((array_size)*sizeof(int)); double *b; b = (double*)malloc(array_size)*sizeof(double)); Then after the use of arrays free the memory by the following; free(a); free(b) ; For two dimensional array: For an array like a[ row_numbers ][ column_numbers ] int** a = malloc((row_nimbers) * sizeof(int*)); for (i=0;i<row_nimbers,i++) {     a[ i ] = malloc((column_nimbers)* sizeof(int)); }  Then after the use of arrays free the memory by the following; for(i = 0; i <row_nimbers; i++) {       free(a[ i ]);  }   For (C++ programming)   int* x = new int[ N

How to install Windows 8/Windows 8.1 and Fedora 20 (Heisenbug) in  dual boot mode with EFI secure boot disabled Hello world, with this new feature of UEFI (Unified Extensible Firmware Interface) boot on the latest motherboards, the installation of Linux OS has become a real pain. But here I am sharing an easy, short and fast way to install Linux (Fedora) OS on a Windows pre-installed machines. To install Linux on a Windows pre-installed machine follow the following steps: (1) Get the *.iso file of the latest issue of Fedora from here (2) Make a bootable DVD from brasero (or any software which can write an iso bootable DVD/CD) or you can also make a bootable USB with UNetbootin . (I specially prefer UNetbootin over start-up disk creator or live-sub-creator, since with UNetbootin you can make bootable usb of any OS, Windows, Fedora, Ubuntu etc.). (3) Disable the secure boot and fast boot for your machine. To know how to do this click here . (4) Now insert your bootable DVD
