Question : 1 Write a C Program to Find the Smallest Number among Three Numbers (integer values) using Nested IF-Else statement.
#include <stdio.h>
int main()
{
int n1, n2, n3;
scanf("%d %d %d", &n1, &n2, &n3);
if(n1<n2)
{
if(n1<n3)
printf("%d is the smallest number.", n1);
else
printf("%d is the smallest number.", n3);
}
else
{
if(n2<n3)
printf("%d is the smallest number.", n2);
else
printf("%d is the smallest number.", n3);
}
}

Question : 2 Write a program to find the factorial of a given number using while loop.
#include<stdio.h>
void main()
{
int n;
long int fact; /* n is the number whose factorial we have to find and fact is the factorial */
scanf("%d",&n);
fact = 1;
int i = 1;
while(i <= n)
{
fact = fact * i;
i++;
}
printf("The Factorial of %d is : %ld",n,fact);
}

Question : 3 Write a Program to find the sum of all even numbers from 1 to N where the value of N is taken as input. [For example when N is 10 then the sum is 2+4+6+8+10 = 30]
#include <stdio.h>
void main()
{
int N, sum=0;
scanf("%d", &N);
for(int i=2; i<=N; i++)
{
if(i%2==0)
sum = sum+i;
}
printf("Sum = %d", sum);
}

Question : 4 Write a C program to calculate the Sum of First and the Last Digit of a given Number. For example if the number is 1234 the result is 1+4 = 5.
#include <stdio.h>
int main()
{
int N, First_digit, Last_digit;
scanf("%d", &N);
Last_digit = N%10;
First_digit = N;
while(First_digit >=10)
{
First_digit = First_digit/10;
}
printf("Sum of First and Last digit = %d", First_digit + Last_digit);
return 0;
}
