Question

I need to separate the integer and fraction part from decimal like 4.343.

Do we have any function in C/C++ which gives the position of the decimal point. After getting that I guess we can convert to numbers using atoi function.

Thanks!

Answer 1

If 4.343 is a string, have a look at strchr.

#include <string.h>

char src[] = "4.343";

char *p = strchr(src, ".");

Then you can use atoi as follow.

#include <stdlib.h>

if (p != NULL)
{
  *p = '\0';
  res = atoi(src);
}
