Indexed sequential file organization. =In indexed sequential file organization, the records arestored in sequence according to a primary key and an index is created to allow random access of the file. This type of organization also allows the file to be accessed sequentially. Indexed sequential is the most commonlyused type of file organization. writer-k.k.b -montanna

Yes. The second clause (the condition) is evaluated before each iteration through a loop. It is possible that a for loop will not execute if its precondition is not met. For example, "for( int x = 5; x < 5; x++ )" will not iterate even once.

Readln discards all other values on the same line, but read does not.

int string_equal (char *p1,char *p2)

{

int status = 1;

while ((*p1 *p2) && status==1)

{

if (*p1++ != *p2++) status = 0;

}

return status;

}

//Reverse of the Number

#include<stdio.h>

#include<conio.h>

int main ()

{

int num,mod,rev=0;

printf("Enter a number:");

scanf("%d", &num);

while (num>0)

{

mod=num%10;

rev=(rev*10)+mod;

num=num/10;

}

printf("Reverse of the given number: %d", rev);

getchar();

return 0;

}

// alternative solution based on reversing the alphanumeric representation of

// the number:

void rev(int me) {

char alpha[32];

sprintf(alpha, "%d", me);

for (const char* cp = alpha + strlen(alpha) - 1; cp >= alpha; --cp) {

putchar(cp); }

}

The file(s) (data) which are accessed in a sequential or a orderly manner is called as a sequentially accessing a file.

nested if Statement

#include #include voidmain() { int a[10]; int i,sum=0; int *ptr; printf("Enter 10 elements:n"); for(i=0;i<10;i++) scanf("%d",&a[i]); ptr = a; /* a=&a[0] */ for(i=0;i<10;i++) { sum = sum + *ptr; //*p=content pointed by 'ptr' ptr++; } printf("The sum of array elements is %d",sum); }

A) #include makes the C/C++ compiler to physically copy the entire header file code into the 'Cor C++' programs, Thus the program size will increase unnecessarily and hence it takes more memory and memory processor time.
Where as import statement makes the JVM to go to Java Library, execute the code there and substitute the result into the Java program "Here no code is copied"...................................




During compilation an .obj file will be light weight in c where as heavy during execution, which is constrant to the .class file

Identifiers are a bit more generic in the context of programming.

If you mean, in terms of the C languages (C, C++, C#), the question is the reverse...keywords may NOT be used as identifiers.

For example, you cannot use keywords such as "int", "float", "double", etc. as the names of variables or objects.

FILE, struct stat and struct tm are some examples.

void main()

{

char str1[30];

char str2[30];

int len1,len2;

printf("Enter string1......:");

gets(str1);

printf("Enter string2......:");

gets(str2);

len1=strlen(str1);

len2=strlen(str2);

printf("%s length = %d",str1,len1);

printf("%s length = %d",str2,len2);

}

Depending on what you're looking at, you may not be able to. My suggestions would be to find the appropriate program used to edit the type of file you're looking at, or to try to find a decompiler for the programming language the file corresponds to.

a Linked List is a Linear collection of self refrential -class objects, called Nodes that's in General. but if you are using Java You can build it Like That.. http://www.cs.fiu.edu/~weiss/dsj3/code/weiss/nonstandard/LinkedList.java if you are using C++ this Link will be helpful http://richardbowles.tripod.com/cpp/linklist/linklist.htm it covers the ideas of a linked list that what i used (C++,Java) i don know what about C# maybe other contributors can help...

/* PROGRAM TO SORT ARRAY ELEMENTS USING BUBBLE SORT*/ #include #include void main() { int i,j,n,t,a[50]; clrscr(); printf("ENTER THE ARRAY SIZE:\n"); scanf("%d",&n); printf("ENTER THE ARRAY ELEMENTS:\n"); for(i=0;i

Syntax error can be found during compilation. Runtime error can be found only when you are trying to execute your program.

Syntax errors are those which are caused by incorrect usage of the programming language. All programming language compilers are designed to detect and report such errors done by the programmer

Runtime errors are those which are caused by incorrect usage of programming logic. for example a runtime divide method will throw a run time error if the divisor is '0' because numerically you cannot divide a number by 0

Array indices are zero-based because the first element is at offset zero from the start of the array. There is no such thing as a one-based array in C. Some other languages do allow you to specify the base of an array, but converting a non-zero-based index to a zero-based index adds a runtime overhead to the implementation.

• Well, I program in C++, and really isn't something you can't do. At least it is the most flexible programming language. If you want something flexible, take C. And I'll give you some more advice: Take C++. C has some really annoying things that C++ fixes. There really aren't limitations. And C and C++ are good. They're the ones you'd start out with, and the ones I'm continuing in, but if you really liked classes in C, you could try Java. It's really class - based.

The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. Following are the types of queue: Linear queue Circular queue Priority queue Double ended queue ( or deque )

-Single pass compiler

-Multi pass compiler

-Cross compiler

-Optimizing compiler
