gets

[Mungovan]

Hi.
Basically I need to input a string of numbers into an array. The user will input a string of < 20 numbers on one line such as &quot;1263444545&quot;, and I want the program to save these as:

myArray[0] = 1;
myArray[1] = 2;
....
....

With the empty ones containing -1.

I think it uses the gets function. How can I implememnt thins?

Thanks for any help.

Something like this?

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main(void);

int main(void)
{
int myArray[20];
int a=0;
char InputNumbers[21];

/* Init myArray with all -1 */
printf(&quot;please enter string of numbers... &quot;
for (a=0;a < 20;a++){
myArray[a]=-1;
}

/* Get the numbers */
gets(InputNumbers);

/* Print numbers entered */
printf(&quot;Numbers entered %s\n&quot;,InputNumbers);

/* Populate the numbers entered in to myArray */
for (a = 0; a < strlen(InputNumbers); a++){
myArray[a] = InputNumbers[a] - '0';
}

/* Print the values in myArray */
for (a=0;a < 20; a++){
printf(&quot;myArray %d = %d\n&quot;,a,myArray[a]);
}
exit(0);

}

gets() is deprecated, and for good reason.
It does no bounds checking.
fgets() is what should be used.
