Question

C: Help with bubble sort. So I've made my array and when I print it it looks fine, but after I run my bubble sort algorithm and try to print it nothing is displayed. Code is as follows:

Answer 1

#include <stdio.h>

int main (void){

int arrayLength = 5;
int array[5] = {4,2,44,1,211};
int i;
int n = 0;
int goal;
int swap;
//start

while (arrayLength != 0){
goal = array[n];
while (n <= arrayLength -1){
if (goal < array[n]){
swap = array[n];
array[n] = goal;
goal = swap;
}
n++;

}
arrayLength--;
}

//print
for (i = 0; i < arrayLength; i++ )
{
printf("%d", array[i]);
}
}

Answer 2

Shouldn't n be zeroed for each iteration of the outer while loop?

Commenting this code will help you double check the logic of the code.
