    strings and numbers

    I have to questions and you might of guessed from the title there about strings and numbers.

    1.) Is there a way so a use can enter a sentance into my program instead of single words. (well want they will be entering is there address because its an address book)?

    2.)Also when I try to save a number with 11 places (a phone number eg. 01298452879) the compilers says its too big how would i be able to save this number into a variable.

    Thanks

    Use fgets and store it into a string. No need to store it as an integer. An int is a 32-bit value and your 11-digit number may exceed the maximum value of an int.
    Try not.
    Do or do not.
    There is no try.

    i don't understand

    Sorry but I don't think I understand that is it possible that you could explain it like you were talking to a 5 year old.

    Thank you

    Perhaps an example would help you see it:

    Code:
    #include <stdio.h>
    
    int main()
    {
       char input[20];
       printf("Enter some words: ");
       fgets(input, 20, stdin);
       printf("\nYou have entered: %s\n", input);
       return 0;
    }
    1) You can store multiple words using fgets. It'll stop when you press return.

    2) Don't store a phone number as a number. Store it as a string. Use the same fgets routine above to handle this.

    BTW, read up on fgets and you'll understand better what the function is doing.

    Hope that helps.
