Hi Vighnesh,

Please explain the term data security.....


Thanks

Answer / priyanka

It gives the value stored at a particular address

Answer / rafiya

Variable is a name given to the memory location of the specified data type.
Pointers are the variables which are capable of storing another variable's address.

Answer / nibedita

Pointers will store the variable address and normal variable
will store the variable value. But if you will declare int *p;
int i=10; and you want to accsess the memory of i you have
to write p=&i; But i can access directly the memory adress
of variable through printf("%d",&i); Then wht is the
difference between pointer and normal variable?

Write an interactive c program that will encode or decode a line of text. To encode a line of text, proceed as follows: Convert each character, including blank spaces, to its ASCII equivalent. Generate a positive random integer. Add this integer to the ASCII equivalent of each character. The same random integer will be used for the entire line of text. Suppose that N1 represents the lowest permissible value in the ASCII code, and N2 represents the highest permissible value. If the number obtained in step 2 above exceeds N2, then subtract the largest possible multiple of N2 from this number, and add the remainder to N1. Hence the encoded number will always fall between N1 and N2, and will therefore always represent some ASCII character. Display the characters that correspond to the encoded ASCII values. The procedure is reversed when decoding a line of text. Be certain, however, that the same random number is used in decoding as was used in encoding.

What is wrong with this code such that it doesnt produce the input reversed? #include <stdio.h> #include <stdlib.h> #include <string.h> int main(void) { char Space = ' '; char LineOfText; float count; LineOfText = getchar(); while ((LineOfText = getchar()) != '/n'); { count = strlen(LineOfText) - 1; while (count >= 0) { putchar(LineOfText[count]); count--; } } getchar(); return 0; }
