Its a simple input that I want to make for char*. Why is this not working? It throws me an exception that I can't resolve..
#include "stdafx.h"
#include "stdio.h"
#include "stdlib.h"
char* GetCharSeq()
{
char *s = (char*)malloc(100);
scanf_s("%s", s);
return s;
}
int main()
{
char* charseq;
charseq = GetCharSeq();
return 0;
}
You have undefined behavior in your code. You have it because you provide to few arguments to the scanf_s
function.
For every string argument, you need to provide not only the destination string but also the size of the string. So change your call to
scanf_s("%s", s, 100);
modify your code
char* GetCharSeq()
{
char *s = (char*)malloc(100);
gets(s);
return s;
}
This will work.
