Bubble Sort?

[Anonymous]

This does not appear to sort random numbers.
// The Bubble Sort!

#include<iostream>
#include<cstdlib>

using namespace std;

int main()      {

int nums[10];
int a, b, t;
int size;

size = 10;//number of elements to sort.

//give array some random initial values
for(t=0; t<size; t++) nums[t] = rand();
//display original array
cout<<"Original array is: ";
for(t=0; t<size; t++) cout<< nums[t] << ' ' ;
cout<<'\n';

//this is the bubble sort
for(a=1; a<size; a++)
for(b=size-1; b>=a; b--)   {

if(nums[b-1] > nums[b])  { //if out of order

//exchange elements
t = nums[b-1];
nums[b-1] = nums[b];
nums[b]=t;

        }
       
        }
        //this is the end of the bubble sort
       
        //display sorted array
        cout<<"Sorted Array is:"  ;
       
        for( t=0; t= size; t++)  cout << nums[t] <<' ' ;
       
      int get();
       
        return 0;
       
        }

This line has an error in your logic, can you see it.  Hint, it involves the middle of the for statement:

for( t=0; t= size; t++) cout << nums[t] <<' ' ;

You typo'ed into an infinite loop, it should read:

for( t=0; t< size; t++) cout << nums[t] <<' ' ;

It seems to work fine once this is fixed.  I put a pause in to my version:

#include<iostream>
#include<cstdlib>
#include<stdlib.h>

using namespace std;

int main() {

int nums[10];
int a, b, t;
int size;

size = 10;//number of elements to sort.

//give array some random initial values
for(t=0; t<size; t++) nums[t] = rand();
//display original array
cout<<"Original array is: ";
for(t=0; t<size; t++) cout<< nums[t] << ' ' ;
cout<<'\n';

//this is the bubble sort
for(a=1; a<size; a++)
for(b=size-1; b>=a; b--) {

if(nums[b-1] > nums[b]) { //if out of order

//exchange elements
t = nums[b-1];
nums[b-1] = nums[b];
nums[b]=t;

}

}
//this is the end of the bubble sort

//display sorted array
cout<<"Sorted Array is:" ;

for( t=0; t< size; t++) cout << nums[t] <<' ' ;

int get();
system("pause");
return 0;

}
