Source code of simple merge sort implementation using array in ascending order in c programming language

#include
#define MAX 50

void mergeSort(int arr[],int low,int mid,int high);
void partition(int arr[],int low,int high);

int main(){

int merge[MAX],i,n;

printf(“Enter the total number of elements: “);
scanf(“%d”,&n);

printf(“Enter the elements which to be sort: “);
for(i=0;i<n;i++){
scanf("%d",&merge[i]);
}

partition(merge,0,n-1);

printf("After merge sorting elements are: ");
for(i=0;i<n;i++){
printf("%d ",merge[i]);
}

return 0;
}

void partition(int arr[],int low,int high){

int mid;

if(low<high){
mid=(low+high)/2;
partition(arr,low,mid);
partition(arr,mid+1,high);
mergeSort(arr,low,mid,high);
}
}

void mergeSort(int arr[],int low,int mid,int high){

int i,m,k,l,temp[MAX];

l=low;
i=low;
m=mid+1;

while((l<=mid)&&(m<=high)){

if(arr[l]mid){
for(k=m;k<=high;k++){
temp[i]=arr[k];
i++;
}
}
else{
for(k=l;k<=mid;k++){
temp[i]=arr[k];
i++;
}
}

for(k=low;k<=high;k++){
arr[k]=temp[k];
}
}

Sample output:

Enter the total number of elements: 5
Enter the elements which to be sort: 2 5 0 9 1
After merge sorting elements are: 0 1 2 5 9
