        one syntax error
        for(i=0;a[i]!=’’;++i)

        this should be like this

        for(int i = 0; a[i] != ‘\0’; ++i)

    Try this…(for geany IDE)
    ===================

    #include
    using namespace std;

    int main( )
    {
    char str[80];
    int flag=0;
    cout << "Enter a string: ";
    cin.getline(str,80);

    int words = 0;

    for(int i = 0; str[i] != '\0'; i++)
    {
    if ((str[i] == ' '||str[i]==',')&&flag==0)
    {
    flag=1;
    words++;
    }
    else if(str[i]!=' '&&str[i]!=',')
    flag=0 ;
    }

    cout << "The number of words = " << words+1 << endl;

    return 0;
    }
