Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

I need to convert this code from C to C++

int main()
{
char number[2000];
FILE *fptr;
if ((fptr = fopen("datafile1.txt","r")) == NULL)

}
if (fgets(number,2000,fptr) != NULL)
fclose(fptr);

char temp;
int i, j;
int n= strlen(number);
freqCount(number, n);
