  1. Array Sort

  2. Sort Pass 1

  3. Sort Pass 2

  4. Sort Pass 3

  5. Sort Pass 4

  6. Bubble Sort - Iterations • 5 elements in array • 4 passes and 4, 3, 2, and 1 iterations • Total 10 • N elements in array • N-1 passes, and N-1, N-2, …, 2, 1 iterations

  7. Implementation - 1 • #include <stdio.h> • int main(void) { • inti, j; • int temp, a[5] = {5, 4, 3, 2, 1}; • for(i=0; i<4; i++) { • for(j=0; j<4-i; j++) { • if(a[j] > a[j+1]) { • temp = a[j]; • a[j] = a[j+1]; • a[j+1] = temp; • } • } • } • for(i=0; i<5; i++) printf("%d ", a[i]); • printf("\n"); • return(0); • }

  8. Implementation - 2 • #include <stdio.h> • void Xchange(int*a, int *b); • int main(void) { • inti, j; • int a[5] = {5, 4, 3, 2, 1}; • for(i=0; i<4; i++) { • for(j=0; j<4-i; j++) { • if(a[j] > a[j+1]) Xchange(&a[j], &a[j+1]); • } • } • for(i=0; i<5; i++) printf("%d ",a[i]); • printf("\n"); • return(0); • } • void Xchange(int *a, int *b) { • int temp; • temp = *a; • *a = *b; • *b = temp; • }

  9. Implementation - 3 • #include <stdio.h> • void Xchange(int*a, int *b); • void PrintArr(intn, int a[]); • int main(void) { • inti, j; • int a[5] = {5, 4, 3, 2, 1}; • for(i=0; i<4; i++) { • for(j=0; j<4-i; j++) • if(a[j] > a[j+1]) • Xchange(&a[j], &a[j+1]); • } • PrintArr(5, a); • return(0); • } • void Xchange(int*a, int *b) { • int temp; • temp = *a; • *a = *b; • *b = temp; • } • void PrintArr(intn, int a[]) { • inti; • for(i=0; i<n; i++) printf("%d ",a[i]); • printf("\n"); • }
