since cursor positioning functions differ from compiler to compiler and environment to environment, only one possible solution is shown for borland C++ under a command-prompt environment.

#include
using namespace std;
void myclreol(int len =- 1);
int main()
{
int i;
gotoxy(1, 1);
for(i=0; i<24; i++)
cout << "abcdefghijklmnopqrstuvwxyz1234567890\n";otoxy(1, 2);
myclreol();
gotoxy(1, 4);
myclreol(20);
return 0;
}
//clear to end line unless len parameter is specified.
void myclreol(int len)
{
int y;
x = wherex(); // get x position
y = wherey() // get y position
if(len== -1) len = 80-x;
int i = x;
for(; i<=len; i++) cout << ' ';
gotoxy(x, y); //reset the cursor

In the C++ standard library is the function strtol(), which has this prototype:
long strtol|(const char*start, const **end, int base);
The function cnverts the numeric string pointed to by start into a long integer. The number base of the numeric string is specified by base. Upon return, end points to the character in the string immediately following the end of the number. The long integer equivalent of the numeric string is returned. base must be in the range 2 to 38. However, most commonly, base 10 is used.
Create a function called mystrtol() that works the same as strtol() except that base is given the default argument of 10. Demonstrate that your version works correctly.
