I am taking an algorithm class and haven't coded in c in around 5 years and realized I have forgotten alot. I tried to use atoi, i know there is a better function but for what I'm using it for and my lack of knowledge now it is simpler, for a program that scans users input and prints out a string as an int until the user types stop. It compiles right but when I run it in putty there is a segmentation fault. Hopefully can steer me in the right direction to do this with atoi so that I can implement this in another program that pushes and pulls numbers in an array. I'm just trying to get the general idea on how atoi works so that I can implement it right in the other program. Thanks.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
main(){
int chartoint;
char * answer = NULL;
do
{
scanf(" %s", &answer);
chartoint = atoi(*answer);
printf("%d\n\n\n", chartoint);
}while ((strcmp("stop",answer)));
return 0;
}
