Question

this is quick sort program it is working for only some digits, can u help me please

#include<iostream>

using namespace std;
class K{

public:
void swap(int *i,int *j){
int temp;
temp=*i;
*i=*j;
*j=temp;

}
int partition(int a[],int low , int high){
int i=-1;
int pivot=high;
for(int j=low;j<high;j++){
if(a[j]<=a[pivot]){
i++;
swap(&a[i],&a[j]);
}
}
swap(&a[i+1],&a[high]);
return(i+1);

}
void quick(int a[],int start,int end) {
if(start<end){

int ip= partition(a,start,end);
quick(a,start,ip-1);
quick(a,ip+1,end);
}
}

};

main(){
int n,j;
cout<<"enter the range for quick sorting";
cin>>n;
int a[n];
for(j=0;j<=n-1;j++){
cout<<"enter element";
cin>>a[j];

}
K obj;
obj.quick(a,0,n-1);
cout<<"displaying sorted array";
for(j=0;j<=n-1;j++){
cout<<a[j];
}

}

Answer 1

Your code is too much complicated and uses very large computational power and when array is bigger than 5 elements the Stack memory completely get exhausted and program crash.

The data of the class must be inside of the class and utility functions are in the private area of the class.

I'll improve it just wait.

Where's from you learnt C++?
