Automatically mount partitions when Ubuntu is started. First, check the system disk code: Fdisk-lDisk/dev/sda: 120.0 GB, 120034123776 bytes255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectorsUnits = sector of 1*512 = 512 bytesSector size (logical/physical): 512 bytes/512 bytesI/O size (minimum/optimal

first row is zero.9. Find the determinant of $$[a]=\begin{bmatrix}0 0 2 3\\ 0 2 3 5\\ 6 7 2 3\\ 6.6 7.7 2.2 3.3\end{bmatrix}$$Solution:Since $R _4 = 1.1r_3$, so $\det (A) = 0$.Find the determinant of $$[a]=\begin{bmatrix}5 0 0 0\\ 0 3 0 0\\ 2 5 6 0\ \ 1 2 3 9\end{bmatrix}$$Solution:This is a lower triangular matrix and hence $$\det (a) = 5\times3\times6\times9=810$$ Given The Matrix $$[a]=\begin{bmatrix}125 25 5 1\\ 512 64 8 1\\ 1157 89 13 Amp 1\\ 8

C is always at the top of all disk partitions.The MBR (primary Boot Record) Partition Table (primary Partition Table) can only store four partitions. To divide more partitions, an extended partition table (EBR) is required ), the extended partition table is placed on a primary partition with the System ID 0x05. The primary partition is an extended partition. The extended partition can be divided into several partitions, each of which is a logical partition. MBR, extended partitions, and l

detecting and identifying memory problems.MEMWATCHMEMWATCH, written by Johan Lindh, is an open-source C-language memory error detection tool. You can download it by yourself. See references later in this article ). After adding a header file in the Code and defining MEMWATCH in the gcc statement, you can track memory leaks and errors in the program. MEMWATCH supports ansi c. It provides results log records, detects double-free release), releases erroneous free by mistake, unfreed memory not rel
