The resulting programs are more efficient, use less processor cycles and memory. Because michine code is the most basic form of language that a processor can understand. It consists of 1's and 0's. It needs no interpreter to interpret to the processor and therefore is the fastest way to tell a processor which commands to run.

It's 1010

You round the 10.25 down to 10, so it's the same as it would be for 10.

This involves allocating and de-allocating memory at run-time. Look into the new and delete operators for C++ or malloc and free for C.

The numerical expression for 36 divided by the sum of 9 and 3 is 36 / (9 + 3).

The strcpy function is declared in the <string.h> header of the C standard library. The function is used to copy a null-terminated string (a null-terminated array of type char). The function accepts two arguments: a pointer to the memory allocation where the copy will be placed; and a pointer to the first character of the null-terminated string to be copied. The memory allocation where the copy will be made must be large enough to accommodate the string, including the null-terminator.

Example usage:

void f (char* s) {

int len;

char* c;

len = strlen (s) + 1; /* determine length of string (including null-terminator) */

c = malloc (len); /* allocate memory for copy */

strcpy (c, s);

/* ... */

free (c); /* release allocation */

}

C is not an OOP language, period. However, while C++ supports OOP it does not rely on it. With C++, you can mix procedural, structured and object-oriented principals by mixing C++ code with C-style code and even raw assembly routines, neither of which are object-oriented.

It will be something like this:

int birthyear = 2001; /* replace it with your birthyear */

int age = 2011 - birthyear;

#include<stdio.h>

#include<conio.h>

using namespace std;

{

int a[20][20],b[20][20],c[20][20],i,j,k,m,n,f;

cout << "Input row and column of A matrix \n\n";

cin >> n >> m;

cout << "\n\nInput A - matrix \n\n";

for(i=0;i<n;++i)

for(j=0;j<m;++j)

cin >> a[i][j];

cout << "\n\nMatrix A : \n\n";

for(i=0;i<n;++i)

for(j=0;j<m;++j)

cout << a[i][j] << " ";

cout << "\n\n";

}

for(i=0;i<m;++i)

for(j=0;j<n;++j)

b[i][j]=a[j][i];

cout << "\n\nTranspose of matrix A is : \n\n";

c[i][j]=0;

The size (and value-range) of int is platform-dependent, whilst that of int32_t is fixed.

An Interrupt is a signal that goes into a microprocessor that tells it something has happened that needs attention. There are generally dedicated pins on the microprocessor, often called "Int" (for Interrupt) and "NMI" (for Non-Maskable Interrupt). For a microprocessor, an interrupt signal is like the bell on a telephone is for you; it's a notice that you should stop what you are doing now and deal with this issue that has come up.

Exact procedures for dealing with an interrupt vary from one microprocessor to another; generally, the microprocessor puts out a signal that says "Where should I go, then?" and a piece of hardware, the Interrupt Controller, then responds with a signal that tells it which condition has happened. The processor then starts processing the indicated piece of code, and that piece of code handles the condition.

The Interrupt Controller often handles setting priority for interrupts, accepting a number of signals (often four), and setting priorities on each. It will trigger another interrupt in the middle of processing one if the new interrupt is a higher priority than the one that is already being processed, or will hold on to the lower priority one until the CPU is finished with a higher-priority one.

The CPU can often "disable interrupts" when it is doing something time-critical. At such times, the only interrupt that can occur is the Non-Maskable Interrupt, which is generally reserved for critical error conditions that have to be dealt with immediately no matter what else is going on.

Array in most programming langauges like C ,C++, Java etc is a static , homogeneous and linear data structure. A data structure itself is a mathematical and logical model to organise data.It clearly specifies the domain of the data that can be stored in the structure and the collection of valid operations (functions) that can be performed on that data. Array is a linear structure in the sense that the data is organised sequentially(one after another in a contineous chunck of memory). It is a homogeneous data structure i.e. it contains elements which are of the same data type.The data type of array can be inbuilt like int , float ,char, double and even user defined that is created using a structure or a class. The main use of an array is to oragnise homogeneous data together as a group to perform operations on data in a collective manner since traversal and retrieval becomes easy.Whenever a homogeneous list(One Dimendional or Multi-Dimensional)has to be implemented we make use of array.The advantage of array lies in the fact that it uses indexed represenattion enabling us to access any member element directly. The example of practical use of array in progarmming will be creation of index lists, pointer arrays,matrix operations(transpose,addition ,subtraction,multiplication,inverse etc.).
