Program does not printf after spaces.

**team23** · 09-18-2010

This program is suppose to be able to display the full address when inputed.
It can only display what is entered before the user hits the space bar.
For example:
When the program ask for the address i'll enter:
254 Marios Castle Lala Land 93884

And only 245 will be displayed.

Here is the code:

PHP Code:




//Write program to display name, address, email address, and with a border.



#include <stdio.h>

void main(void)

{

    char name[50];

    char address[50];

    char email_address[50];



    printf("\nPlease type your name:\n");

    scanf("%s", &name);

    printf("%s \n", name);

    

    printf("\nPlease enter your address:\n:");

    scanf("%s", &address);

    printf("%s \n", address);

    

    printf("\nPlease enter your email address:\n:");

    scanf("%s", &email_address);

    printf("%s\n", email_address);

    

}

The problem lies with your input method: it would be easier to read correctly if you used something like fgets instead of scanf, since %s causes the read to stop at whitespace.

Incidentally, you should not be taking of address of name, address and email_address when using them with scanf. Those arrays would be converted to pointers to the first characters.

Use this.

Code:

#include <stdio.h>

int main(void) {
    char name[50];
    char address[50];
    char email_address[50];
    
    printf("\nPlease type your name:\n");
    fgets(name, sizeof(name), stdin);
    printf("%s \n", name);
    
    printf("\nPlease enter your address:\n:");
    fgets(address, sizeof(address), stdin);
    printf("%s \n", address);
    
    printf("\nPlease enter your email address:\n:");
    fgets(email_address, sizeof(email_address), stdin);
    printf("%s\n", email_address);
}

scanf stops reading input when it reads a space. fgets doesn't.

Nice syntax coloring, by the way.

also gets(address); is used when working with strings, and is white space friendly, but is very dangerous!
