C Programming

A keyword identifier is one whose meaning has already been declared to the C compiler and we can't use it as variable,because if we want to do so we are trying to establish a new meaning to the keywords which is not permitted.

There's a nice for Loop at the link below.

To write a C program to determine if something is odd or even you need to be a programmer. To write a program in C is complicate and only done by programmers.

hi,

it is basically start up program that is responsible for locating lower hard disk addresses where operating system is stored

Example: *(int *)main = 5;

C was developed by Dennis Ritchie at AT &T's Bell Laboratories of USA in 1972.

Simply print a new line before invoking any return statement within the main function:

#include<stdio.h>

int main(void) {

// ...

printf ("\n"); // print a new line to the stdout device

return 0; // end the program (0 typically indicates no error)

}

special character in c language are as follows~ ' ! @ # % ^ & * () _ - + = | \ {} [] : ; " <> , . ? /

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();

}
