C Program to Manipulate String without Use of Manipulation Functions

#include <stdio.h>

#include <conio.h>

void main()

{

    char str[30]="Deepraj",copy[30],rev[30];

    int i,j;

    printf("The string is %s",str);

    /*C Program to Find the Length of String without strlen() */

    for(i=0;str[i]!='\0';i++);  /* i contains the length of string */
  printf("\nLength of the string is %d",i);

    /*C Program to Copy String without strcpy() */

    for(i=0;str[i]!='\0';i++)

    {

        copy[i]=str[i];

    }

    copy[i]='\0';

    printf("\nCopy of the string is %s",copy);

    /*C Program to Reverse the String without strrev() */

    for(i=0;str[i]!='\0';i++); /* i contains the length of string */

    i--;

    for(j=0;i>=0;j++,i--)

    {

        rev[j]=str[i];

    }

    rev[j]='\0';

    printf("\nReverse of the string is %s",rev);
