Write code , Multiple characters move from both ends , Converging in the middle , The renderings are as follows ：

The code is as follows ：

#include<stdio.h>
#include<string.h>
#include<Windows.h>
int  main()
{
    
     char  arr1[]="welcome to bit!!!!!!";
     char  arr2[]="######################";
     int  left=0;
     int  right=strlen(arr1)-1;// Be careful strlen Header file is required, otherwise there will be a warning 
                                  // Use header file #include<strig.h>
    while(left<=right)
     {
    
     arr1[left]=arr2[left];
     arr2[right]=arr1[right];
      printf("%s\n",arr2);
      Sleep(1000);// rest 1000 millisecond （ sleep 1 second ）, Note that header files must be added #include<windows.h>
      system（"cla");// Clear the screen ;
     left++;
     right—-;   
   }  
   printf("%s\n",arr2);
   return 0;
}

strlen subtract 1 reason ： because strlen The length of the string is found , from 1 At the beginning , And the subscript is from 0 At the beginning , So subtract 1 To get the corresponding subscript ;

summary

Hopefully that helped , Remember to pay attention to the third company ！
