C Programming

Robotics programming is usually done in C or a derivative of C, although it's entirely possible for other languages to be used. For example, "RobotC" is a common language used for various micro-controllers, however it's now possible to use Java as well with Sparkfun's "IOIO" microcontroller.

#include "stdio.h" int main() { unsigned int number, count; printf("Enter the Number \t"); scanf("%d", &number); printf("The even numbers are: \n"); for(count = 0x01; (count < number && number!= 0x00)) { if(count%2) { }else { printf("%d\n", count); } count++; } return 0; }

You should use arrays when you have several pieces of related data, of the same type. As an example, let's suppose you have a series of measurements, for example, temperature measured every few minutes. It doesn't make sense (from a programming point of view) to use a different variable for every measurement, so you store the measurements as a group - as an array.

The six basic computer operations, as pertaining to a pseudocode algorithm, are:

1. A computer can receive information.

2. A computer can put out information.

3. A computer can perform arithmetic.

4. A computer can assign a value to a variable or memory location.

5. A computer can compare two variables and select one of two alternative actions.

6. A computer can repeat a group of actions.

Write a merits and demerits of using function in program

Header files allow programmers to separate interfaces from implementations. Typically, a header file contains the declaration of a single class or a group of related classes or functions, or both. The definitions are typically placed in a corresponding source file (which must include the header), although inline functions are often defined in the header itself, while incomplete types such as template classes and template functions must always be defined in the header.

Although you could place all your code in a single file, header files make it easier to re-use common functions and classes from other programs. You can also build libraries of common classes and functions, each of which requires a header (the interface) that must be included in your source in order for your programs to be able to link to those libraries. Thus headers are an aid to modularisation and re-usability, thereby reducing the need to write duplicate code.

#include<stdio.h> #include<conio.h> int i=1, count=0,n; clrscr(); printf("Enter Any Number"); scanf("%d", &n); while(i<n) if(n%i==0) { count++; i++; } if(count==2) printf("Given Number is Prime"); else printf("Given Number is not Prime"); getch(); }

Every input device attached to the motherboard bus lines has a direct line of communication with the CPU. These lines are known as interrupt request lines (IRQs) which can be prioritised. By signalling the CPU that an input is pending, the CPU can alert the operating system to deal with the request, which will then be prioritised accordingly.

its simple

just do this swappping

for(i=0;i<m;i++) /*A*/

for(j=0;j<i;j++) /*B*/

{

x=a[i][j];

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

a[j][i]=x;

}

I think A and B need a change :

/*Permutation : */

for ( i = 0 ; i <= lig ; i++ ) /*A*/

for ( j = 0 ; j <= i ; j++ ) /*B*/

{

int permut = MatA[i][j] ;

MatA[i][j] = MatA[j][i] ;

MatA[j][i] = permut ;

}

/*End of permutation */

printf("\nDISPLAY MATRIX : \n") ;

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

{

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

{

printf("%d", MatA[i][j]) ;

}

printf("\n") ;

}

Internal sorting

it means we are arranging the number within the array only which is in computer primary memory.

External sorting

it is the sorting of numbers from the external file by reading it from secondary memory.

That depends on how you look at it. The point of the JVM is to allow Java bytecode to be executed on any platform, regardless of what machine it was compiled on.

The actual implementation of the JVM, however, must be platform-specific.

A set which containing $and pi are the end blocks are the finite and without these are infinite

pointer is used when we want to retain the change in values between the function calls.

Similarly double pointer is used when we want to retain the change in pointers between the function calls. If you want to modify pointers than you need double pointer to retain the change.

That kind of loop is referred to as an Infinite Loop. It occurs when the exit conditions can never be met or when the programmer fails to supply an exit.

For example:

Do while (1>0)

(that will loop forever because 1 is always greater than 0)

for (int i = 0; i < myArray.length(); i++) System.out.println(myArray[i]);

#include<stdio.h>

#include<conio.h>

int main(void)

{

int a[100][100]={0}; /* initializing matrices to '0' */

int b[100][100]={0};

int c[100][100]={0}; /*matrix-c for multiplication*/

/*r1,c1 are rows and coloumns for matrix-a.r2,c2 for matrix-b.*/

int r1,c1,r2,c2;

int i,j,k;

clrscr();

printf("enter the no of ROWS and COLOUMNS for MATRIX-A\n");

scanf("%d %d",&r1,&c1);

printf("enter the no of ROWS and COLOUMNS for MATRIX-B\n");

scanf("%d %d",&r2,&c2);

if(c1==r2)

{

printf("matrix multiplication possible\n\nenter numbers in MATRIX-A\n");

/* to enter numbers in matrix-a*/

for(i=0;i<r1;i++)

for(j=0;j<c1;j++)

scanf("%d",&a[i][j]);

printf("enter numbers in MATRIX-B\n");

/* to enter numbers in matrix-b*/

for(i=0;i<r2;i++)

for(j=0;j<c2;j++)

scanf("%d",&b[i][j]);

/*for matrices multiplication*/

for(i=0;i<r1;i++)

for(j=0;j<c2;j++)

for(k=0;k<c1;k++)

*(*(c+i)+j)+=*(*(a+i)+j)*(*(*(b+k)+j));

printf("result of multiplication of matrices is \n");

/*to display as matrix format*/

for(i=0;j<r1;i++)

{

printf("\n");

for(j=0;j<c2;j++)

printf("%d\t",*(*(c+i)+j));

}

} //if

else

printf("MATRIX multiplication not Possible\n");

getch();

return 0;

}

The do while loop is useful for the special loops that they must circulate at least one time.

#include <iostream>

using namespace std;

int main()

{

int num,digit;

cout<<"Enter a #\n";

cin>>num;

cout<<"Invers is : ";

do

{

digit=num/10;

cout<<digit;

num/=10;

} while(num != 0);

return 0;

}

Quicksort in any programming language is an algorithm for sorting data sequences. It is typically implemented as follows (example demonstrates a quicksort of an array of type int). Note that a half-open range, [begin:end), includes the one-past-the-end of the range and is the conventional means of defining a range of contiguous array values. When begin==end, the range is deemed empty.

// forward declarations

void qsort (int* unsigned); // this is the function you will actually invoke

void qsort_rec (int*, int*); // recursive function

int* partition (int*, int*); // utility functions...

int* select_pivot (int*, int*);

void swap (int*, int*);

int count (int*, int*);

// sort a data sequence of length size

void qsort (int* data, unsigned size) {

qsort_rec (data, data + size);

}

// recursively sort the half-open range [begin:end)

void qsort_rec (int* begin, int* end) {

if (count (begin, end) < 2) return; // end point of recursion

int* pivot = partition (begin, end);

qsort_rec (begin, pivot);

qsort_rec (++pivot, end);

}

// divide the half-open range [begin:end) into two around a pivot value

int* partition (int* begin, int* end) {

if (count (begin, end) < 2) return begin;

int* pivot = select_pivot (begin, end);

swap (begin, pivot);

--end;

while (begin != end) {

while (*(begin) <= *pivot && begin != end) ++begin;

while (*pivot < *(end) && begin != end) --end;

if (begin!=end) swap (begin, end);

}

assert (begin==end); // sanity check!

swap (pivot, begin);

return begin;

}

// select the median of three from a half-open range [begin:end)

int* select_pivot (int* begin, int* end) {

int* mid = begin + (count (begin, end) / 2);

if (*end<*begin) swap (begin, end);

if (*mid<*begin) swap (begin, mid);

if (*end<*mid) swap (mid, end);

return end;

}

// swap the values referred to by p and q

void swap (int* p, int* q) {

if (!p !q) return; // sanity check!

int t = *p;

*p = *q;

*q = t;

}

// count the elements in the half-closed range [begin:end)

int count (int* begin, int* end) {

int cnt = 0;

int add;

if (begin>end) { // swap pointers if the range is reversed

int* t = begin;

begin = end;

end = t;

add = -1; // count will be negative

} else {

add = 1; // count will be positive

}

while (begin++!=end) cnt+=add;

return cnt;

}

A structured program is not OO, yet still exhibits low coupling and high cohesion.
