C Descending Order
What is descending order?
Mathematically, when certain sets of numbers are arranged from largest number to the smallest number then they are said to be descending order
Sounding as a programmer, descending order can only be performed in array data type, because array is the only place where you can store certain sets of data in a consecutive memory location for future use.
C Prgram - Descending Order
Let us code descending order in C program and have some fun
#include <stdio.h>
int main()
{
int i, j, n, a[30], temp = 0;
printf("\nEnter a number : ");
scanf("%d", &n);
printf("\nEnter %d numbers to sort ");
for(i = 0;i < n;i++)
scanf("%d", &a[i]);
for(i = 0;i < n-1;i++)
{
for(j = i;j < n;j++)
{
if(a[i] < a[j])
{
temp = a[i];
a[i] = a[j];
a[j] = temp;
}
}
}
printf("\n----Descending Order---- ");
for(i = 0;i < n;i++)
printf("%d ", a[i]);
return 0;
}
Enter a number : 5 Enter Numbers to sort : 27 24 29 22 26 ----Descending Order---- 29 27 26 24 22
Note:
First of all, we ask our user to enter a limit, then we use an array to get the user entered input. Now we have an array of all user entered number. Now it's time to arrange all user entered input in an descending order. For that we use 2 things.
- 2 for loops
- temperary variable called temp
First for loop is used to hold the first value in a[] array whereas second for loop is used to scan the numbers in a[] from 1st element to last element. If the number in a[i] is lesser than a[j] then swapping is done by using our temperary variable temp. This kind of swapping of two numbers in an array is said to be bubble sort algorithm.
