## C Program To Find Smallest Digit of a Number

Learn How To Find Smallest Digit of a Number in C Programming Language. This C Program To Search the Smallest Digit in an Integer makes use of **Division** and **Modulus** operators primarily. The Modulus operator is used to **extract** the digit at the end of a given number.

We have written two methods to Search for the Smallest Digit in a Number which includes a While Loop and a For Loop. Here, we have initialized the variable **small** with **10** as it is the highest value any digit in a number can be. So, whenever you fetch any digit, it can go upto 9 as its maximum value.
