Reverse a string in C language

how to reverse a string in C language ?

this is the code

#include<stdio.h>

int main()

{

    int a,A;

    char array[101],temp;

    scanf("%s",&array);

    a=0;

    while(a>=0)

    {

        if(array[a]=='\0')break;

        a++;

    }

    for(A=0;A<=a/2;A++)

    {

        temp=array[A];

        array[A]=array[a-A-1];

        array[a-A-1]=temp;

    }

    for(A=0;A<a;A++)

    {

       printf("%c",array[A]);

    }

    return 0;

}

or you can simply using function in strrev in string.h

#include<stdio.h>

#include<string.h>

  

int main()

{

   char array[101];

scanf("%s",&array);

   printf("After reversing string is =%s",strrev(str));

   return 0;

}

strrev is not recommended for use in competitive coding

that is all from me

thank you
