Two types of sorting in c?

1. Selection sorting method

Require input 10 integers, sort output from largest to smallest

Input: 2 0 3 -4 8 9 5 1 7 6

Output: 9 8 7 6 5 3 2 1 0 -4

Code:

#include<stdio.h>

int main(int argc,const char*argv[]){

int num[10],i,j,k,l,temp;

// Use an array to save the input data

for(i=0;i<=9;i++)

{

scanf("%d",&num<i>);

}

/// Use two for nested loops for data size comparison for sorting

for(j=0;j<9;j++)

{

for(k=j+1;k<=9;k++)

{

if(num[j]<num[k])//num[j]<num[k]

{

temp=num[j];

num[j]= num[k];

num[k]=temp;

}

}

}

/// Use a for loop to output the sorted data from the array

for(l=0;l<=9;l++)

{

printf("%d",num[l]);

}

return 0;

}

2. Bubble Sort Method

Requires input of 10 integers, sort output from largest to smallest

Input: 2 0 3-4 8 9 5 1 7 6

Output: 9 8 7 6 5 3 2 1 0 -4

Code:

#include<stdio.h>

int main(int argc,const char*argv[]){

/// Use an array to store data

int num[10],i,j ,k,l,temp;

Use for to read data in one by one

for(i=0;i<=9;i++)

{

scanf("%d",&num<i>);

}

// Use two layers of for loops to compare the data for bubbling

for(j=0;j<9;j++)

{

for(k=0;k<9-j;k++)

{

if(num[k]<num [k+1])//num[k]<num[k+1]

{

temp=num[k];

num[k]=num[k+1];

num[k+1]=temp;

}

}

}

. p>// Use a for loop to output the sorted data from the array

for(l=0;l<=9;l++)

{

printf("%d",num[l]);

}

return 0;

}

Temp[k+1]=temp;

This is the first time I've used the for loop. strong>Extended information:

Return 0 means that the program exited normally. return is a C++ predefined statement that provides a way to terminate the execution of a function. When the return statement provides a value, that value becomes the return value of the function.

The return statement is used to end a loop, or to return the value of a function.

1. return 0, indicating that the program exits normally and returns to the main program to continue down the execution.

2, return 1, that the program is abnormal exit, return to the main function to deal with, continue to execute down. return 0 or return 1 on the program execution order has no effect, just that we are accustomed to the use of return (0) to exit the subroutine only.
