Title: give a group of arrays, arranged from large to small and from small to large.

subject ： Give a set of arrays , Arrange from large to small and from small to large .

Write first C The structure of language

#include <stdio.h>

int main()
{
    
    
    //C Basic structure of language 
    
    
    return 0;
}

First step ： First define a set of arrays

#include <stdio.h>

int main()
{
    
    
  int a[10];// there 10 Represents size ,
	int data;
    
    
    return 0;
}

The second step ： Get into C The cycle of language （ Complete code ）

#include <stdio.h>

int main()
{
    
    
    int a[10];// there 10 Represents size ,
	int data;

	for(data=0;data<=9;data++){
    
		a[data]=data*1;
	}
		printf(" Array initialization complete \n");
		
	
	for(data=0;data<=9;data++){
    
		printf(" In positive order address:%p,data:%d\n",&a[data],a[data]);// hold data Print out the address and value of 
	}
	
	printf("\n");
	
	// In reverse order 
	for(data=9;data>=0;data--){
    
		a[data]=data*1;
	}
	
	for(data=9;data>=0;data--){
    
		printf(" In reverse order address:%p,data:%d\n",&a[data],a[data]);
	}
	printf("done\n");
    
    
    return 0;
}
