C Smallest Number

Suppose, if one of your friend giving you two cards and asking you to return a card which contains smallest number among two cards, it's very easy for you to return, there is no big deal. Now, the same guy came upto you and asking you to write a c program to find and output the smallest number among two numbers and he restricted you by saying that "input will be given by him and not by you".

C Program - Smallest Number

It's time to write a c program to find the smallest number among two numbers.

#include <stdio.h>
int main()
int num1, num2;
printf("\nEnter the number 1 : ");
printf("\nEnter the number 2 : ");
printf("\nSmallest Number : \n%d ", num2>num1 ? num1:num2);
return 0;
Enter the number 1 : 5
Enter the number 2 : 10
Smallest number : 5


In the above program, condition operator checks whether num2 is greater than num1, if the condition true num1 is outputted else num2 is outputted.
