The output should contain the 10 numbers from the range
1-1000 which should pick randomly, ie ,for each time we run
the code we should get different outputs.

randomize();
printf("Ten random numbers from 0 to 1000\n\n");
for(i=0; i<10; i++)
printf("%d\n", rand() % 100);

Answer / kap
it is not the correct answer because the range they asked 0-
1000 so need to to %1000. :-)

Answer / nischal e rao
The best way to solve this problem would be to create a hash
function and apply the current time to as the argument to
the hash function. the hash function should be designed to
return a number between 1 to 1000.

Answer / sharan
if the randomize(); doesn't work
replace it with srand ((unsigned) time (NULL));

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.
