C ++ review the nine Bubble sorting method

Objective: To learn the Bubble Sorting Algorithm experiment content: implement the Bubble Sorting Algorithm and define it as a function. The parameter is a pointer variable pointing to an array.

# Include <iostream> using namespace STD; void bubble_sort (int * P, int num); // sort void output_array (int *, INT ); // output the sorted array int main () {int A [20] = }; int B [15] = {, 73}; bubble_sort (A, 20 ); // sort the elements output_array (A, 20) in a in descending order using the bubble method; // output the sorted array bubble_sort (B, 15 ); // sort the elements output_array (B, 15) in B in descending order using the bubble method; // output the sorted array return 0 ;} // The following custom function void bubble_sort (int * P, int num) {int I, j, T; // I, j is the control variable, T is the intermediate variable for (j = 0; j <= num-1; j ++) {for (I = 0; I <num-1-j; I ++) {If (* (p + I + 1)> * (p + I) // if the next number is greater than the previous one, the switching position {T = * (p + I ); * (p + I) = * (p + I + 1); * (p + I + 1) = T ;}}} void output_array (int * P, int num) {int I; for (I = 0; I <num; I ++) {cout <* (p + I) <"";} cout <Endl ;}
Running result:
Experience Accumulation: Bubble Sorting is very impressive, and it is always time to move a bigger or smaller one forward,
I think that, in my life, I keep putting the problems solved at the end, and putting new and important problems at the front.
When you solve the problem, the path you walk will be displayed at your feet !!!
