C program to sort an array in descending order
Problem
Sort the given array in descending or ascending order based on the code that has been written.
Solution
An array is a group of related data items which share’s a common name. A particular value in an array is identified with the help of its "index number".
Declaring array
The syntax for declaring an array is as follows −
datatype array_name [size];
For example,
float marks [50]
It declares ‘marks’ to be an array containing 50 float elements.
int number[10]
It declares the ‘number’ as an array to contain a maximum of 10 integer constants.
Each element is identified by using an "array index".
Accessing array elements is easy by using the array index.
Program
Following is the C program to sort an array in descending order −
#include <stdio.h>
void main (){
int num[20];
int i, j, a, n;
printf("enter number of elements in an array
");
scanf("%d", &n);
printf("Enter the elements
");
for (i = 0; i < n; ++i)
scanf("%d", &num[i]);
for (i = 0; i < n; ++i){
for (j = i + 1; j < n; ++j){
if (num[i] < num[j]){
a = num[i];
num[i] = num[j];
num[j] = a;
}
}
}
printf("The numbers in descending order is:
");
for (i = 0; i < n; ++i){
printf("%d
", num[i]);
}
}Output
When the above program is executed, it produces the following result −
enter number of elements in an array 4 Enter the elements 11 34 67 89 The numbers in descending order is: 89 67 34 11
