[c-prog] Try this Build-In Function

[Vishnu Kumar]

Hi,

The following build-in function (acceptNumber, acceptAlpha) are used to get the 
input from the user. The special in that function is it only accepts 
number/char.

#include <stdio.h>
#include <conio.h>

int main()
{
     int acceptNumber();
     char* accptAlpha();
     int number;
     printf("Enter the Number ");
     number = acceptNumber();
     printf("\n The Input Number is %d ", number);
}

int acceptNumber()
{
     char ch,number=0;
     do
     {
     ch = getch();
     if(ch >= '0' && ch <= '9')
     {
         number = (number * 10) + (ch - 48);
         putchar(ch);
     }
     }
     while(ch != 13);
     return number;
}

char* accptAlpha()
{
    char alpha[100],ch;
    int index = 0;
    do
    {
     ch = getch();
     if((ch >= 'a' && ch <='z') || (ch >='A' && ch <='Z'))
     {
         alpha[index++] = ch;
         putchar(ch);
     }
    }
    while(ch != 13);
    alpha[index] = '\0';
}
