C Program to Find First and Last Digit of a Number
http://technotip.com/6766/c-program-t...
Write a C program to find first and last digit of the user input number, without using looping.
if num = 123;
count = log10(num); // count = 2;
first = num / pow(10, count); // first = 1;
last = num % 10; // last = 3;
Both pow() and log10() are built-in methods present in header file math.h So we include that library file at the beginning of our C program source code.
