    EXPERIMENT
    OBJECTIVE:

    Write a C program to test whether a given identifier is valid or not

    RESOURCE:

    C++

    PROGRAM LOGIC:

    Read the given input string.


    Check the initial character of the string is numerical or any special character except ‘_’ then
    print it is not a valid identifier.
    Otherwise print it as valid identifier if remaining characters of string doesn't contains any
    special characters except ‘_’

    PROCEDURE:

    Go to run or press Ctrl+Atl+N run the program.

    PROGRAM:
    #include<stdio.h>
    #include<conio.h>
    #include<ctype.h>
    #include<iostream>
    using namespace std;
    int main()
    {
    char a[10];
    int flag,i=1;
    cout<<"\n Enter an Identifier:";
    gets(a);
    if(isalpha(a[0]))
    {
    flag=1;
    }
    else
    {
    cout<<"\n Not A valid identifier:";
    }
    while (a[i]!='\0')
    {
    if(!isdigit(a[i]) && !isalpha(a[i]))
    {
    flag=0;
    break;
    }
    i++;
    }
    if(flag==1)
    {
    cout<<"\nValid Identifier";
    }
    return 0;
    }
