Here, we will sort the elements of an array in descending order using a C program.
Example:
Input:
array = [45, 22, 100, 66, 37]
Output:
[100, 66, 45, 37, 22]
Method 1:
The for loops iterate the array of elements and then the if statement compares the first element of an array with other all elements, the second element of an array with other elements, and so on, to print the descending order of an array.
C
// C program to sort array elements in descending order #include <stdio.h> int main()
{ int a[5] = { 45, 22, 100, 66, 37 };
int n = 5, i, j, t = 0;
// iterates the array elements
for (i = 0; i < n; i++) {
// iterates the array elements from index 1
for (j = i + 1; j < n; j++) {
// comparing the array elements, to set array
// elements in descending order
if (a[i] < a[j]) {
t = a[i];
a[i] = a[j];
a[j] = t;
}
}
}
// printing the output
for (i = 0; i < n; i++) {
printf("%d ", a[i]);
}
return 0;
} |
Output
100 66 45 37 22
Method 2: Using functions
C
// C program to sort array elements in descending order // using functions #include <stdio.h> // defining the function int desc_order(int a[10], int n)
{ int i, j, t = 0;
// iterates the array elements
for (i = 0; i < n; i++) {
// iterates the array elements from index 1
for (j = i + 1; j < n; j++) {
// comparing the array elements, to set array
// elements in descending order
if (a[i] < a[j]) {
t = a[i];
a[i] = a[j];
a[j] = t;
}
}
}
// printing the output
for (i = 0; i < n; i++) {
printf("%d ", a[i]);
}
return 0;
} int main()
{ int arr[5] = { 45, 22, 100, 66, 37 };
int num = 5;
// calling the function
desc_order(arr, num);
} |
Output
100 66 45 37 22
