C PROGRAMS : FUNDAMENTALS
11. Program to input a number and find whether it is even or odd
#include<stdio.h>
#include<conio.h> // Linux user - Remove this

int main()
{
 // Declaring variale "n" to store input number
 int n,r;
 
 // Inputting number
 printf("Enter a number : ");
 scanf("%d", &n);
 
 // Checking if input number is ever or odd
 if(n%2==0)
 printf("Entered number is even");
 else
 printf("Entered number is odd");
 
 getch(); // Linux user - Remove this

 return 0;
}

12. Program to find biggest of four no by using ternary numbers
#include<stdio.h>
#include<conio.h> // Linux user - Remove this

int main()
{
 // Declaring variable a, b, c, d to store 4 numbers input by user
 int a,b,c,d;
 
 // Declaring variable big to store the biggest value
 int big;

 // Inputting number
 printf("Enter first number : ");
 scanf("%d",&a);
 printf("Enter second number : ");
 scanf("%d",&b);
 printf("Enter thirda number : ");
 scanf("%d",&c);
 printf("Enter fourth number : ");
 scanf("%d",&d);
 
 // Determining biggest number
 big=(a>b)?(a>c)?(a>d)?a:d:(c>d)?c:d:(b>c)?(b>d)?b:d:(c>d)?c:d;

 
 // Printing smallest number
 printf("Biggest of four number = %d",big);
 
 getch(); // Linux user - Remove this

 return 0;
}

13. Program to print smallest of four no by using ternary operators
#include<stdio.h>
#include<conio.h> // Linux user - Remove this

int main()
{
 // Declaring variable a, b, c, d to store 4 numbers input by user
 int a,b,c,d;
 
 // Declaring variable small to store the smallest value
 int small;

 // Inputting number
 printf("Enter first number : ");
 scanf("%d",&a);
 printf("Enter second number : ");
 scanf("%d",&b);
 printf("Enter thirda number : ");
 scanf("%d",&c);
 printf("Enter fourth number : ");
 scanf("%d",&d);
 
 // Determining smallest number
 small=(a<b)?(a<c)?(a<d)?a:d:(c<d)?c:d:(b<c)?(b<d)?b:d:(c<d)?c:d;
 
 // Printing smallest number
 printf("Smallest of four number = %d",small);
 
 getch(); // Linux user - Remove this

 return 0;
}

14. Program to accept a year and check the given year is leap or not by using ternary
#include<stdio.h>
#include<conio.h> // Linux user - Remove this


int main()
{
 // Declaring variable "y" to input year and "leap" to determine leap year
 int y,leap;
 
 // Inputting year
 printf("Enter any year : ");
 scanf("%d",&y);
 
 // Checking if leaf year or not
 leap=(y%400==0)?:(y%100!=0)?(y%4==0)?1:0:0;

 if(leap==1)
 printf("The given year is leap year");
 else
 printf("The given year is not leap year");

 getch(); // Linux user - Remove this

 return 0;
}
15. Program to find area of a triangle when there sides are given
# include <stdio.h>
# include <conio.h> // Linux user - Remove this


int main( )
 {
 // Declaring variable a, b, c = to store three sides of triangle
 int a,b,c;
 
 // Declaring variable s = mid value
 float s, area;

 // Inputing sides of triangle
 printf("Enter there sides of the triangle : ");
 scanf("%d%d%d",&a,&b,&c);
 
 // Checking if finding area is possible or not
 if((a+b)<c||(b+c)<a||(a+c)<b)
 printf("Finding area is not possible");
 
 // Calculating area
 else
 {
 s=(a+b+c)/2;
 area=sqrt(s*(s-a)*(s-b)*(s-c));
 }
 
 // Printing area
 printf("Area=%.2f",area);
 
 getch( ); // Linux user - Remove this

 return 0;
}
