    In ‘\0’ condition the program is not terminating,,its counting ‘\0’ also and giving the result

    in calculating the length of the string do ‘\0’ also counts????

  4. instead of char *str you must put char str[ ]

    is it ok to replace get with scanf?

    • Chetan Singh Sengar says:

      Ya it is Ok but you can mostly use the gets because of it is easy way to scan a string 😀

  6. “clrscr();” what is this?
    is this true?

    • Subhajit Bhattacharjee says:

      clrscr(); ::is a function which is mainly used for clear the output screen..if you dont write it in your program then the output screen also show your previous output…

    Word Count Program

    #include
    #include
    void main(){
    char *str;
    int count = 0,i;
    int WordCount=1;
    clrscr();
    printf(“\nEnter the String: “);
    gets(str);
    for(i=0;str[i]!=’\0′;i++){
    count++;
    if(str[i]==’ ‘)
    WordCount++;

    }
    printf(“\nThe length of the string is %d.”,count);
    Printf(“WordCount is:%d”,WordCount);
    getch();
    }

    Output : Enter The String: Hi Hello Everybody
    lenth of the string is :19
    WordCount is: 3

    kindly give me a program in string function that could tell if the word is a palindrome.. 🙂

      char *st,*ptr;
      int i;
      clrscr();
      printf(“enter the string to scan : “);
      gets(st);
      strcpy(ptr,st);
      strrev(st);
      i=strcmp(ptr,st);
      if(i==0)
      printf(“Entered string is palindrome…”);
      printf(“Entered string is not palindrome…”);
      getch();
      }

  11. clrscr();
    is clear the screen before all of the items be printed off or display

    char *str;
    int len,i;
    clrscr();
    printf(“\nEnter the String: “);

    len=i;
    }
    printf(“\nThe length of the string is %d.”,len);
    getch();
    }

    will this one work fine???

  13. no it will print (n-1) characters ,becoz u taking ‘i’ value initiate with ‘0’ so it will display of length (length-1)

  14. Abin Rimal says:

    Instead why can’t we use sizeof() function,
    like
    #include
    #include
    #include
    void main()
    {
    char str[]=”this is the string time”;
    cout<<sizeof(str);
    }

  15. DIPU ANAND PATEL says:

    write a c program to sort a list of string according to the length of the string in descending order using a two dimensional array. The program will continue accepting string until and unless “END” is typed.The program should have two functions i.e main and another reorder(to arrange the list of string). you cannot use any predefined string functions such as strcmp or strcpy or even strlen.

    Sir is that possible that we can make a program which print itself in the function ? :/ :/

  17. Chetan Singh Sengar says:

    Sir i can’t understand the Malloc() & Calloc() is there anyone who tells me abot them with example in a easy way ? :/ :/
