C Program for finding Second Largest Number in the given array of elements

Program

#include<stdio.h>
#include<conio.h>
void main()
{
int a[100],i,j,temp,n;
        clrscr( );//clear the screen contents
printf("\nEnter size of the Array:");
scanf("%d",&n);
printf("\nEnter elements to Array:");
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}
for(i=0;i<n;i++)// Sorting logic begins
{
for(j=0;j<n-i-1;j++)
{
if(a[j]>a[j+1])
{
temp=a[j];
a[j]=a[j+1];
a[j+1]=temp;
}
}
}//ends
printf("Second largest: %d",a[n-2]);
getch();
}


Input/Output:

Enter size of the Array: 5

Enter elements to Array:5
4
8
2
1
Second largest: 5

Program:

#include<stdio.h>  //header file
#include<conio.h>  //header file
int odd(int); // funtion proto type
void main( )
{ //main function begins
          int n;
          printf("\nEnter a Number:");
          scanf("%d",&n);
          if(odd(n))
          {
                printf("\n Given Number is ODD");
           }
           else
           {
                printf("\n Given Number is EVEN");
            }
}//main function ends
int odd(int n)
{
           if(n&1)
           {
                      return 1;
            }
            else
            {
                       return 0;
             }
}

Input/Output:
