Question

Here is my code

#include <stdio.h>

int main(void){

    int unsorted[] = {1,3,4,5,2};
    int i = 0;
    int j = 0;
    int temp = 0;
    for(i = 1; i <= 5; i++){
        temp = unsorted[i];
        j = i - 1;
        while(unsorted[j] > unsorted[i]){
                unsorted[i] = unsorted[j];
                unsorted[j] = temp;
            }

}
        for(i = 0; i < 5; i++){
        printf("%i", unsorted[i]);
    }
    return 0;
}

The output is 13425. It's entering the while loop enough times to move the 2(the last element) to its place, but for some reason it isn't.

La solution

Try like this:

#include <stdio.h>
int main(void){

    int unsorted[] = {1,3,4,5,2};
    int i = 0;
    int j = 0;
    int temp = 0;
    for(i = 1; i < 5; i++){
        j = i;
        while(j>0 && unsorted[j]<unsorted[j-1]){
                temp = unsorted[j];
                unsorted[j] = unsorted[j-1];
                unsorted[j-1] = temp;
                j--;
            }

}
    for(i = 0; i < 5; i++){
    printf("%d", unsorted[i]);
}
return 0;

}

        j = i - 1;
        while(unsorted[j] > unsorted[i]){
            // you need to place j-th element in (j+1)-th
            // position, but not in i-th position
            unsorted[i] = unsorted[j];
            unsorted[j] = temp; // you can do this one time after end of this cycle
            // You need to decrement j in this cycle until j >= 0
        }

    }
    for(i = 0; i < 5; i++){
        printf("%i", unsorted[i]);
    }
    return 0;
