The ASCII Character Set or ASCII Chart

ASCII stands for American Standard Code for Information Interchange. ASCII is a 7 bit alphanumeric code used in computers. Each character is assigned with a positive integer (in between 0 and 127). This is the most popular coding system. The following is the ASCII chart of characters and corresponding integer value.

How to Hard Reset Nokia E63

This post will teach you how to hard reset Nokia E63, symbian smartphone. The same method can be

applied to hard reset similar E series phones, some other symbian phones and even some of the new Java phones from Nokia. Hard resetting is complete cleansing of phone memory and the firmware will repaired/reinstalled.

So when you hard reset your phone, it will result in loss of data including your contacts in phone memory and whatever you have stored in phone memory. To avoid loss of any important data, your can back up your data onto your memory card. There is an option provided in the phone to backup all the phone memory to memory card. To know how to backup your data, watch this video: http://www.youtube.com/watch?v=yPpqwhU4ErM

To hard reset your phone, Follow these instructions:

Nokia 603 Symbian

Nokia 603 is a symbian Belle full touch smartphone. Hard resetting may solve most of the problems with its software. I have reset one to solve a problem with the phone software and the problem was successfully solved. The problem was that when a link in any messages or notes are clicked, an error was shown and the web browser cannot be loaded. This was solved by hard resetting the phone using the three button combination.

C and C++ Programs for String Sorting

Here i am writing programs in c and c++ languages to sort a given number of strings. Sorting is carried out based on the ASCII values of the letters in the strings. The string comparing function strcmp() is used in the program. These programs sort a given set of strings in ascending order.To change it into descending order just replace > with < in comparison line. The comparison line in the code is marked by comment.

C Program:

#include<stdio.h>
#include<string.h>
#include<conio.h>
void main()
{

C Program for Subtraction Without Using Minus Sign

The following is a program to subtract a number from another without using minus symbol. Instead of doing a normal subtract operation, the two's complement of the subtrahend is added to the minuend. (In 3-4, 3 is minuend and 4 is subtrahend.) In other words, the 1's complement and 1 is added to minuend.

#include<stdio.h>
void main()
{
int a,b,sum;
printf("Enter any two integers: ");

scanf("%d%d",&a,&b);
sum = a + ~b + 1;
printf("Difference of two integers: %d",sum);
}

C and C++ Programs to Find Sum of Digits of a Given Number

The following are C and C++ programs to find sum of digits of any given integer.

C Program

#include<stdio.h>
#include<conio.h>
void main()
{

C and C++ Program for Swapping Two Numbers Without Third Variable

This post contains C and C ++ programs for swapping two given numbers without using any temporary variable. Only the two variables are required, not a third.

C Program

#include<stdio.h>
void main()
{

C and C++ swapping numbers

The following are C and C++ programs to swap the values of two variables using a third variable.

C Program:

#include<stdio.h>
void main()
{
int x,y,temp;
printf("Enter the value of xand y\n");
scanf("%d%d", &x, &y);
printf("Before Swapping\n x= %d\n y = %d\n",x,y);
temp = x;
x= y;
y = temp;
printf("After Swapping\n x= %d\ny= %d\n",x,y);
}

2 Different C and C++ Programs to Check Whether a Given String is Palindrome or Not

Here i am writing two different programs to check whether a given string (text) us palindrome or not. There are C and C++ programs for this.

C Programs:

(i) Using string functions:

#include<stdio.h>
#include<string.h>
#include<conio.h>
void main()
{
char a[100],b[100];
printf("Enter the string to check if palindrome or not\n");
gets(a);
strcpy(b,a);
strrev(b);
if(strcmp(a,b)==0)
printf("\nEntered string is palindrome");
else
printf("\nEntered string is not palindrome");
getch();
}

(ii) Comparing Character by Character

#include<string.h>
#include<stdio.h>
#include<conio.h>
void main()
{
int len,i;
char a[100];
printf("Enter the string to check whether it is palindrome or not\n");
gets(a);
len=strlen(a);
for(i=0;i<len/2;i++)
{
if(a[i]!=a[len-i-1])
break;
}

if(i==len/2)
printf("\nEntered string is palindrome");
else
printf("\nEntered string is not palindrome");
getch();
}

C++ Programs:

(i) Using String functions:
