C Programming

You don't say whether you mean physical memory or virtual memory. Regardless, there is no portable method given that memory management is system-specific. However, the system should provide some means of giving you the information you need. The following example works on Windows and Linux:

#ifdef WIN32 #include <windows.h>

unsigned long long getTotalSystemMemory()

{

MEMORYSTATUSEX status;

status.dwLength = sizeof(status);

GlobalMemoryStatusEx(&status);

return status.ullTotalPhys;

}

#else // UNIX...

#include <unistd.h>

unsigned long long getTotalSystemMemory()

{

long pages = sysconf(_SC_PHYS_PAGES);

long page_size = sysconf(_SC_PAGE_SIZE);

return pages * page_size;

}

#endif

For example we have a class :

public class Test()

{

public void print()

{

System.out.println("Hello");

}

}

So, if you want to create array from Test type. You can try something like this :

Test[]myTestArray=new Test[2];

myTestArray[0]=new Test();

myTestArray[1]=new Test();

I hope it will help.

1. draw terminal symbol
2. draw I/O symbol (parallelogram) to get array elements in a variable (e)
3. draw process symbol (rectangle) to define array. e.g ary(e)
4. draw decision box to check number of iterations (i<=e)
5. if condition is true then take input in array (ary(i))
6. take variable to sum each element of array:(s=s+ary(i))
7. go to step 4
8. if given condition in step 4 becomes false then print variable a, containing sum
9. end up the flowchart

Switch case can be flowcharted using a diamond for each case, with a right branch for true and a down branch for false. The false branch simply connects to the next case. The true branch connects to the statement that should be executed for that case. Where multiple cases result in the same statement, the true branches should converge upon that statement. The execution path from the statement(s) should converge with the final false branch of the switch case.

In this case, your switch case might be as as follows:

print %letter%

switch lowercase (%letter%)

{

case 'a':

case 'e':

case 'i':

case 'o':

case 'u':

print line " is vowel"

break;

default:

print line " is not vowel"

}

Thus you will have a column of diamonds for each case with false branches linking downwards from one diamond to the next. The statement for case 'a', 'e', 'i', 'o' and 'u' is the same, so their true branches (extending to the right) will converge upon the 'print line " is vowel"' statement which must be placed to the right of the case diamonds. The default case's true branch leads to the 'print line " is not vowel"' statement. Both these statements will then converge with the false branch from the default case, marking the end of the switch case.

Note that, logically, there is no false branch from a default case, thus this link may be omitted. However, all links from all statements must still converge below the default case.

Identifiers or symbols are the names you supply for variables,type,function and labels.Identifiers names must differ in spelling and case from any keyword.you cannot use keyword as an identifier.you can create an identifier by specifying it in the declaration of a variable,type or function.

It usually means "circa" meaning around or approximately.

In languages that use a C-style syntax (e.g., C, C++ and Java) all code is written using expressions. Expressions may be combined to produce more complex expressions, however an expression or group of expressions only becomes a statement when terminated by a semi-colon. A group of statements enclosed by braces {} is known as a compound statement or code block.

void main()

{

int arr[4][4];

int i,j,a,b,f;

printf("\nInput numbers to 4*4 matrix");

for(i=0;i<4;i++)

{

for(j=0;j<4;j++)

{

printf("\nKey in the [%d][%d]) value",i+1,j+1);

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

}

}

for(i=0;i<4;i++)

{

for(j=0,f=0;j<4;j++)

{

if(i!=j&&f==0)

continue;

a=arr[i][j];

b=arr[j][i];

arr[i][j]=b;

arr[j][i]=a;

f=1;

}

}

for(i=0;i<4;i++)

{

for(j=0;j<4;j++)

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

printf("\n");

}

}

A binary number system has two states '0' '1' for a long word in bits it can be as follows 101010101010101010101011 intimidating RIGHT? it can be represented in groups of 3 bits in octal 10/010/101/010/101/010/101/011= 22525253 digital or in group of 4 bits as 10/1010/1010/1010/1010/1010 = 2AAAAA

111 =7 octal 1111=f F in hexadecimal numbers 1000 =8 1010 =10 or A

There are only two methods: pass by value and pass by reference. The function itself determines how arguments are passed into the function, as defined by the function signature. If the function accepts a reference, then the argument is passed by reference, otherwise it is passed by value. Pointers are always passed by value but behave like references. The only real difference is that pointer values may be NULL but references can never be NULL.

This is not a C++ question. It is an operating system question. Different operating systems have different ways of making programs run on startup. Most of them have several different ways to accomplish this. In MS Windows, one way is to place a shortcut for the program in the "{percent}userprofile{percent}\Start Menu\Programs\Startup" shell folder.
