### Sorting Array Elements Using Bubble Sort in C Programming

In previous post we discussed about how to pass an array into function. In following simple program we will create a function which will accept an array as an input. We will pass an array as input to a function called bubblesort. That function will then sort the elements of the array in ascending order.

[js]

#include <stdio.h>

void bubbleSort(int arr[], int size); // function prototype

int main(void){

int arrayName[10] = {90,44,33,83,49,34,51,84,56,44}; // defined an array with 10 elements

//output each element of array
printf("Original values of the arraynn");
printf("Array indextttValuen");
for(int j=0; j<10; j++){
printf("%11dttt%4dn", j, arrayName[j]);
}

bubbleSort(arrayName, 10); // function call

//output each element of array
printf("nnValues of the array after passing to the bubbleSort functionnn");
printf("Array indextttValuen");
for(int j=0; j<10; j++){
printf("%11dttt%4dn", j, arrayName[j]);
}

return 0;
}

//function definition
void bubbleSort(int arr[], int size){
//BubbleSort algorithm will sort the array elements in ascending order. Outer loop is for passes and inner loop will do comparisons
for(int l=1; l<=size; l++){
for(int m=0; m<size-1; m++){
if(arr[m]>arr[m+1]){
int temp;
temp = arr[m];
arr[m] = arr[m+1];
arr[m+1] = temp;
}
}
}
}

[/js]

Output:
