C Programming

well , in a rather simple way

an expression is a combination of of literals , variables , operators , functions calls which produces a particular value to be used in any other context

while a statement is an instruction to the computer telling it what to do for instance assigning an expression value to a variable , cause it produces an instructions tells the computer to assign a value to something.

to be more accurate , you can tell if A is a statement or an expression accurately by looking at the context which is been used in

Answer If it weren't for computer languages where would we be today. Can you imagine writing a program as simply as writing a sentence instead of using computer language, it would be impossible. CD/delete means one thing, CD:/change direction and if the double dots aren't there the computer won't recognise the command. That's why so many people especially Computer Programmers spend years in Schools learning computer language so that the every day joe can't do their jobs.

Use a looping structure. The first step initialises a loop control variable, n, to zero. You then begin the loop by processing the nth element from the array (the process may be a simple print statement). You then increment n. Finally, you test the value of n; if it is less than 10 you start a new iteration of the loop, otherwise you proceed to the end of the flowchart.

#include<stdio.h>

#include<conio.h>

void main()

{

float f1,*Ptr1,*Ptr2;

ptr1 = &fl;

ptr2 = (&fl+1);

printf("%u",(char *)ptr2-(char *)ptr1);

getch();

}

void main() { int a,b; clrscr(); printf("\n\n\t\tenter any two nos..."); scanf("%d%d",&a,&b); a=a+b; b=a-b; a=a-b; printf("\n\n\t\tvalue of a=",a); printf("\n\n\t\tvalue of b=",b); getch(); }

A language that allows you to combine high-level programming with low-level programming. C and C++ are generally regarded as being mid-level languages.

C language eveloped by Dennis Ritchie at the Bell Telephone Laboratories.

Variable-declaration is:

extern int x;

extern double y;

extern char a;

Variable-definition is:

int x;

static double y;

auto char a;

Variable-definition with initialization is:

int x = 1;

static double y= 2.3;

auto char a = 'w';

int i = 2;

while (i <= 1000) {

printf ("%d\n", i);

i++;

}

The while loop is good for scenarios where you don't know how many times a block or statement should repeat, but you want to continue looping as long as some condition is true. A while statement looks like this:

while (expression) {

// do stuff

}

In this case, as in all loops, the expression (test) must evaluate to a boolean result. The body of the while loop will only execute if the expression (sometimes called the "condition") results in a value of true. Once inside the loop, the loop body will repeat until the condition is no longer met because it evaluates to false.

Any variables used in the expression of a while loop must be declared before the expression is evaluated. In other words, you can't say

while (int x = 2) { } // This is not legal

The key point to remember about a while loop is that it might not run at all. If the test expression is false the first time the while expression is checked, the loop body will be skipped and the program will begin executing at the first statement after the while loop. Look at the following example:

int x = 8;

while (x > 8) {

System.out.println("in the loop");

x = 10;

}

System.out.println("past the loop");

Running this code produces

past the loop

Because the expression (x > 8) evaluates to false, none of the code within the while loop ever executes.

//program to find the age of given date of birth

#include <dos.h>

#include <stdio.h>

int main(void)

{

struct date d;

int bd,bm,by,day,m,y,cd,cm,cy;

clrscr();

getdate(&d);

printf("\t**********WELCOME TO AGE FINDER PLACE************\n");

printf("\t*************************************************\n\n");

cd=d.da_day;

cm=d.da_mon;

cy=d.da_year;

printf("Enter the birthe date : ");

scanf("d%d",&bd,&bm,&by);

{

if(cd<bd)

{

cm=cm-1;

cd=cd+30;

day=cd-bd;

}else

day=d.da_day-bd;

}

{

if(cm<bm)

{

cy=cy-1;

cm=cm+12;

m=cm-bm;

}else

m=d.da_mon-bm;

}

y=cy-by;

printf("your age is:-\n");

printf("year=%d\tmonth=%d\tday=%d\n",y,m,day);

getch();

}

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.
