        In case you have stored a string
        Ex: RAHUL
        This is called string variable. Here RAHUL is stored as 012345 and at the end of the string a Null character will be added. The compiler will automatically add the null character.

        R 0
        A 1
        H 2
        U 3
        L 4
        NULL 5

        What is the algorithm to reverse a string?

        We need to know the length of the string. To find the length of the string we use

        str len ();

        This functions find the length, which can be stored in a variable.

        Var = str len ();
        for (i = var-1; i>=0; i–)
        {
        print f (“%c”, str[i])

        ==========================================

        Follow the below program to Write a function to reverse a string without using concatenation

        # include < stdio.h>
        # include <conio.h>
        # include <string.h>
        main()
        {
        Char str(10);
        int len;
        printf(“enter a string”);
        scanf(“%s”, str);
        len=strlen (str);

        for (i=len-1; i>=0; i–)
        {

        printf(“%c”, str[i];
        }
        getch();
        }
