scanf() used for common variable do

[hughLg]

scanf() used for common variable does works. when variable like double and long double within the structure get from scanf(), undesireable result produces.

Could you post the scanf line and the struct definition ?

 

[hughLg]

sure.

#include <stdio.h>

typedef struct stock {
char id[5];
float num;
double num1;
long double num2;
} stock_t;

int
main()
{
stock_t var;
scanf(&quot;%f&quot;, &var.num);
/* following 2 cause unexpected result. */
scanf(&quot;%f&quot;, &var.num1);
scanf(&quot;%f&quot;, &var.num2);
return 0;
}

Its not because of scanf, but becuase you have used %f for double & long double.

Try:

   scanf("%lf", &var.num1);
   scanf("%llf", &var.num2);
