Array Sort

Sort Pass 1

Sort Pass 2

Sort Pass 3

Sort Pass 4

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

Implementation - 1 #include int main(void) { int i, 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); }

Implementation - 2 #include void Xchange(int *a, int *b); int main(void) { int i, 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; }

Implementation - 3 #include void Xchange(int *a, int *b); void PrintArr(int n, int a[]); int main(void) { int i, 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(int n, int a[]) { int i; for(i=0; i<n; i++) printf("%d ",a[i]); printf("\n"); }
