write a program in c/c++ to print a new no. by adding one to each of its digit.?

Question

.if a five digit no. is input through the keyboard .write a program in c/c++ to print a new no. by adding one to each of its digit.e.g. 12391 then output must be 23402.

Answer 1

You MIGHT think the answer is as simple as adding 11111 to the number, but that would be incorrect, since 12391 + 11111 = 23502 (not 23402)...

Thus, we need to account for the "9" which (according to the specification) must yield a "0" result and not a "10" (i.e. "carry")...

So...
the code fragment for this would look something like this...

int i, digits[5], input=12391;
/* Extract the digits and add 1 to each & get single digit answer*/

for (i=4; i>=0; i--) {
digits[i] = (input%10 + 1) %10;
input/=10;
}

/* print the digits in order */
for (i=0; i<5; i++)
putchar (digits[i] + '0');

}

Answer 2

Since there are only 10 digits, easiest way is to create an array of that maps number 0 to 9, to its new value, then iterate through input and get the output from the defined mapping array.
